Designing a Header Compression mechanism for efficient use of IP tunneling in wireless networks
2010 7th IEEE Consumer Communications and Networking Conference, CCNC 2010, 2010Co-Authors: Priyanka Rawat, Jean-marie BonninAbstract:The IP tunneling mechanisms are used in various contexts such as network security, IP transition, and mobility support. However, these tunneling mechanisms induce a large Header overhead that leads to performance deterioration on wireless links which have scarce resources. Header Compression methods can be used on tunnel Headers to reduce the protocol Header overheads, independently of the payload type. Though, several Header Compression methods exist, the Header Compression profiles defined by them are not adapted to the characteristics of IP tunneling. In view of this, we design a novel tunneling Header Compression protocol (TuCP) for efficient use of IP tunneling mechanisms in wireless networks. The TuCP protocol behavior is analyzed by studying the implementation parameters and their configuration. Several experiments are conducted to measure the performance of TuCP. The experiment results are used to configure TuCP for enabling a better Compression of IPv6 flows and managing packet reordering problem in IP tunnels.

Robust Header Compression over long delay links
2008Co-Authors: Priyanka Rawat, Jean-marie Bonnin, Laurent Toutain, Yanghee ChoiAbstract:The enormous growth in the use of the IP-based multimedia and other applications has increased the need to use the available communication technologies including satellite and radio links efficiently. These wireless links generally induce high bit error rates and long delays. Moreover, the deployment of IP protocols over these links leads to significant Header overhead. IP tunneling mechanisms, widely used in the network security, IPv4-to-IPv6 transition, and mobile networks also have long delay characteristics. This paper studies the behavior of one of the most commonly used Robust Header Compression (ROHC) mechanism over such long delay links and tunnels. We show the impact of long delay, high bit error rate, and packet reordering on ROHC performance. Some of the experiments have been conducted over L2TP tunnel between France and Korea. The results show that ROHC Compression can be used over long delay links to reduce Header overheads with certain limitations. The results presented in this paper will provide the basis for further designing Header Compression schemes specifically suited for links and tunnels with long delays.

unidirectional robust Header Compression for reliable low latency mesh networks
International Conference on Communications, 2019Co-Authors: Mate Tomoskozi, Frank H P Fitzek, Daniel E Lucani, Peter EklerAbstract:Next generation use-cases of mesh networks, such as connected vehicles and industrial devices, require low latency transmissions while fulfilling high reliability constraints. However, they also suffer from an increased protocol encapsulation overhead when handling a large number of messages with small payloads. A solution to this problem is to employ Header Compression algorithms in order to reduce the size of the individual protocol Headers. Unfortunately, the current state-of-the-art Header Compression schemes cannot be readily applied to network topologies that contain a combination of multiple-hops and paths, as the Compression only works favourably on a peer-to-peer, single-hop basis. With the unique combination of network coding and Header Compression one can always utilise unidirectional Compression with maximum gain. In this paper we introduce and evaluate, for the first time, an integrated network coded Header Compression solution, which we call unidirectional Robust Header Compression (uRoHC). We show that one can – proportionally to the logical payload size – double the payload delivery efficiency compared to standard IPv4 and that we achieve results 10–15 % better than that of RoHCv2 for streams containing 33 bytes of payload.

Header Compression in Opportunistic Routing
2018Co-Authors: Mate Toemoeskoezi, Frank H P Fitzek, Ievgenii Tsokalo, Sreekrishna Pandi, Peter EklerAbstract:Next generation use-cases of wireless mesh networks, especially the Massive Machine Type Communications and IoT applications require the capability to handle a large number of connections while maintaining a low-energy usage. In such cases, the transmissions between source and destination can employ multiple paths. The throughput in a scenario like this can be maximised with application of Opportunistic Routing (OpR). In high density networks, the OpR uses the diversity of the broadcast channel to increase the achievable data rates in comparison to traditional routing solutions. However, the Header size of the routing messages increases when the density grows. The reduction of this overhead could potentially improve the overall throughput and decrease the battery usage of network heavy applications via diminished wireless interface activity. Normally, Header Compression is employed to minimise the overhead of IP-based cellular traffic between two connected peers. This paper presents for the first time the application of Header Compression concepts to an opportunistic routing protocol. We use a packet erasure channel simulator to employ these Header Compression techniques on the routing messages based on real world mesh network traces. We thereby decrease the size of the routing messages in these simulated topologies and find that they can reduce the size of transmission heavy Header elements by at least 50 % and can be even as high as 85 % under certain conditions. This increases the potential of opportunistic routing in very large mesh networks, as the reduction in feedback message sizes would increase the maximum achievable data rates exponentially.

Performance Evaluation of Network Header Compression Schemes for UDP, RTP and TCP
Periodica Polytechnica Electrical Engineering and Computer Science, 2016Co-Authors: Mate Tomoskozi, Patrick Seeling, Peter Ekler, Frank H P FitzekAbstract:Modern cellular networks utilising the Long–Term Evolution (LTE) set of standards face an ever–increasing demand for mobile data from connected devices. Header Compression is employed to minimise the overhead for IP–based cellular network traffic. In this paper, we evaluate the three Header Compression implementations used by such networks with respect to their potential throughput increase and complexity for different mobile service scenarios. We compare RTP, UDP and TCP profile Compressions regarding their Compression gain and complexity. Specifically, we consider Header Compression as defined by (i) IP Header Compression (RFC 2507), (ii) Robust Header Compression version 1 (RFC 3095), and (iii) the recently updated Robust Header Compression version 2 (RFC 5225) with TCP/IP profile (RFC 6846). This paper presents the performance evaluation of these Header Compression schemes for UDP, RTP and TCP, for both IPv4 and IPv6 streams in error–free and error–prone scenarios. A comparison between the Robust Header Compression methods and IP Header Compression is also provided. Our results show that all implementations have great potential for saving bandwidth in IP–based wireless networks, even under varying channel conditions. We also present for the first time an analysis of certain RTP Header fields which, depending on the transmission characteristics, could have high impact on the overall Compression gain.

design and evaluation of ip Header Compression for cellular controlled p2p networks
International Conference on Communications, 2007Co-Authors: Tatiana Kozlova Madsen, Frank H P Fitzek, Qi Zhang, M. KatzAbstract:In this paper we advocate to exploit terminal cooperation to stabilize IP communication using Header Compression. The terminal cooperation is based on direct communication between terminals using short range communication and simultaneously being connected to the cellular service access point. The short range link is than used to provide first aid information to heal the decompressor state of the neighboring node in case of a packet loss on the cellular link. IP Header Compression schemes are used to increase the spectral and power efficiency loosing robustness of the communication compared to the uncompressed version. By introducing the terminal cooperation supporting Header Compression the robustness is increased. Within this article we will show that Header Compression should be applied to reduce the energy consumption of the terminals and moreover the Header Compression should be supported by cooperation to increase the robustness in terms of a decreased packet loss rate.

Performance Analysis of Header Compression Schemes in Heterogeneous Wireless Multi–Hop Networks
Wireless Personal Communications, 2006Co-Authors: Patrick Seeling, Martin Reisslein, Tatiana Kozlova Madsen, Frank H P FitzekAbstract:Wireless multi–hop networks are becoming more popular and the demand for multimedia services in these networks rises with the number of their implementations. Header Compression schemes that compress the IP/UDP/RTP Headers to save bandwidth for multimedia streams were typically evaluated only for individual links, not taking into account the savings that can be achieved using Header Compression over a complete path. In this paper, we evaluate the performance of three categories of Header Compression schemes: ( i ) delta coding, ( ii ) framed delta coding, and ( iii ) framed referential coding. We evaluate the performance for these schemes on reliable and unreliable links. We then extend our evaluations to several links constituting a path. As nodes in multi–hop ad-hoc and mesh networks may differ with respect to their capabilities, we assume in our evaluation that (forwarding) nodes may not be able or choose not to perform Header Compression. We find that the framed referential Header Compression scheme is the most suitable scheme in case that no or long-delay feedback channels exist. We additionally compare the packet drop savings due to Header Compression and the combined savings of Compression and drops. We again find that the framed referential coding scheme exhibits good performance that can lead to significant Header Compression and packet drop savings for reasonable bit error rates.

Tunneling Header Compression (TuCP) for Tunneling over IP
2009Co-Authors: Ana Minaburo, Priyanka Rawat, Bonnin J-m, Eun PaikAbstract:The IP tunneling mechanisms have important applications in network solutions and are widely used in numerous contexts such as security (VPN), IPv4 to IPv6 transition, and mobility support (MobileIP and NEMO). However, these tunneling mechanisms induce a large overhead resulting from adding several protocol Headers in each packet. This overhead deteriorates performance on wireless links which are scarce in resources. Header Compression methods are often used on connection oriented communication (e.g., UMTS networks) to reduce the overhead on the wireless part. These Header Compression methods can be used on tunnel Headers to reduce the protocol Header overheads, independent of the payload type. Although, several Header Compression methods exist, the Header Compression profiles defined by them are not adapted to the characteristics of IP tunneling. This document specifies a tunneling Header Compression protocol for IP tunneling mechanisms.

Low‐loss TCP/IP Header Compression for wireless networks
Wireless Networks, 1997Co-Authors: Mikael Degermark, Mathias Engan, Björn Nordgren, Stephen PinkAbstract:Wireless is becoming a popular way to connect mobile computers to the Internet and other networks. The bandwidth of wireless links will probably always be limited due to properties of the physical medium and regulatory limits on the use of frequencies for radio communication. Therefore, it is necessary for network protocols to utilize the available bandwidth efficiently. Headers of IP packets are growing and the bandwidth required for transmitting Headers is increasing. With the coming of IPv6 the address size increases from 4 to 16 bytes and the basic IP Header increases from 20 to 40 bytes. Moreover, most mobility schemes tunnel packets addressed to mobile hosts by adding an extra IP Header or extra routing information, typically increasing the size of TCP/IPv4 Headers to 60 bytes and TCP/IPv6 Headers to 100 bytes. In this paper, we provide new Header Compression schemes for UDP/IP and TCP/IP protocols. We show how to reduce the size of UDP/IP Headers by an order of magnitude, down to four to five bytes. Our method works over simplex links, lossy links, multi‐access links, and supports multicast communication. We also show how to generalize the most commonly used method for Header Compression for TCP/IPv4, developed by Jacobson, to IPv6 and multiple IP Headers. The resulting scheme unfortunately reduces TCP throughput over lossy links due to unfavorable interaction with TCP's congestion control mechanisms. However, by adding two simple mechanisms the potential gain from Header Compression can be realized over lossy wireless networks as well as point‐to‐point modem links.

A Linux Kernel Implementation of MANET IP Header Compression
2014 IEEE Military Communications Conference, 2014Co-Authors: Bownan Cheng, Tak Wong, Brian HungAbstract:The desire for both industry and U.S. Department of Defense (DoD) to converge on an all-IP infrastructure, fueled by the increased usage of mobile applications on smart phones and VoIP applications have driven research in maximizing bandwidth efficiency amidst a shrinking allocation of radio frequency (RF) spectrum. One method of providing increased bandwidth efficiency (especially with the desire to move to IPv6), is the use of IP Header Compression schemes like MANET IP Header Compression (MIPHC) to compress IP Headers into small identifiers before sending packets to the link layer. MIPHC was designed as a shared-state IP Header Compression protocol and yields less Compression than other protocols like RObust Header Compression (ROHC), but requires no state exchange. One key aspect of evaluating the applicability of MIPHC in military networks is a high fidelity implementation. In this paper, we present a Linux kernel implementation of MIPHC which includes a performance evaluation of the implementation in an emulated MANET network.

a comparison of ip Header Compression schemes in manets
International Performance Computing and Communications Conference, 2013Co-Authors: Bownan Cheng, Scott Moore, Brian Hung, James Wheeler, Prasanna SukumarAbstract:The desire to increase bandwidth efficiency in an all-IP infrastructure in the presence of reduced spectrum and increasing demand for connectivity has led to several developments in IP Header Compression techniques. In recent years, there have been several IP Header Compression schemes developed in industry specifically for wireless networks including RObust Header Compression (ROHC) and IP Header Compression (RFC 2507). ROHC and IPHC (RFC 2507) have been adopted by several commercial cellular networks and military networks as one of the techniques for implementing IP Header Compression. In addition to ROHC and IPHC which were designed primarily for one-hop wireless networks, MANET IP Header Compression (MIPHC) was defined to help bridge the gap to multi-hop MANETs. To evaluate the effectiveness of IP Header Compression schemes on multi-hop MANETs and other networks, we implement simulation models of ROHC, IPHC, and MIPHC and evaluate their performance under various conditions in a mobile ad hoc network. The results show that although ROHC was designed specifically for one-hop cellular networks and context is required to be maintained per hop per IP flow, its performance is fairly good in multi-hop MANETs.

manet ip Header Compression
Military Communications Conference, 2013Co-Authors: Bownan Cheng, John Zuena, Jim Wheeler, Scott Moore, Brian HungAbstract:The desire for DoD communications systems to converge on an all-IP infrastructure, fueled by the increased usage of net-centric IP applications at the tactical edge have pushed research in maximizing bandwidth efficiency amidst a shrinking allocation of RF spectrum. One method of providing increased bandwidth efficiency (especially with the desire to move to IPv6), is the use of IP Header Compression (IPHC) techniques such as IP Header Compression (RFC2507), RObust Header Compression (ROHC-RFC5225), and others, to compress Headers. Although widely used in one-hop cellular networks, many IPHC schemes today are stateful in that they build hop-by-hop Compression state per flow. Maintaining this per-hop state per flow, however, becomes increasingly difficult in MANET environments where next-hop information is constantly changing. In this paper, we propose a shared-state/stateless IP Header Compression scheme tailored to MANET environments called MANET IP Header Compression (MIPHC). We show that although MIPHC does not achieve the same load reduction as ROHC for single-hop wireless networks, there are gains in MANET environments due to lack of need to build Compression context on a hop-by-hop basis. MIPHC can also be combined with other protocols to compress higher layer Headers.

internet protocol Header Compression technology and its applicability on the tactical edge
IEEE Communications Magazine, 2013Co-Authors: Bownan Cheng, James Wheeler, Brian HungAbstract:The increased usage of net-centric IP applications at the tactical edge has pushed DoD communications systems to maximize bandwidth efficiency amid a limited availability of RF spectrum. One method of increasing bandwidth efficiency (especially with the desire to move to IPv6), is the use of IP Header Compression (IPHC) to compress Headers from the network layer and above into small identifiers before sending to the link layer. Although widely used in cell phone technology, the tactical edge provides some unique challenges to traditional IPHC techniques including highly dynamic links and link conditions due to potential jamming threats and difficult environments, multi-hop scenarios due to lack of infrastructure, and a highly diverse set of radio systems lacking interoperability. In this article, we examine two common IP Header Compression schemes, Robust Header Compression (RFC 5225) and IP Header Compression (RFC 2507) and one experimental scheme, MANET IP Header Compression, and identify their current use and applicability in the tactical edge. Furthermore, we identify some challenges in implementing Header Compression schemes in emerging systems.
