Rate of convergence for the `square root formula' in the Internet transmission control protocol
Advances in Applied Probability, 2006Co-Authors: Teunis J. OttAbstract:The 'square root formula' in the Internet transmission control protocol (TCP) states that if the probability p of packet loss becomes small and there is independence between packets, then the stationary distribution of the congestion window W is such that the distribution of W√p is almost independent of p and is completely characterizable. This paper gives an elementary proof of the convergence of the stationary distributions for a much wider class of processes that includes classical TCP as well as T. Kelly's 'scalable TCP'. This paper also gives stochastic dominance results that translate to a rate of convergence.

Implementation and evaluation of scalable Vehicle-to-Vehicle transmission control protocol
2010 IEEE Vehicular Networking Conference VNC 2010, 2010Co-Authors: Ching-ling Huang, Hariharan Krishnan, Raja Sengupta, Yaser Pourmohammadi FallahAbstract:Vehicle-to-Vehicle (V2V) communications play a critical role in enabling important cooperative safety applications. V2V safety communications rely on broadcast of self-state information (e.g., position, speed, and heading) by each vehicle, which allows a vehicle to track its neighboring vehicles in real-time. One of the most pressing challenges in this research is to maintain an acceptable tracking accuracy of neighboring vehicles while avoiding congestion in the shared communication channel. In this paper we describe the evaluation of a transmission control protocol that adapts the message rate and transmission power for V2V safety communications. This protocol has been implemented on V2V test vehicles with wireless radios and integrated with existing active safety applications. The testing and evaluation results show that proposed communication design works well in practice, its performance matches the observation from previous simulations and shows great promise for a large-scale deployment of V2V cooperative safety systems.

A packet-reordering solution to wireless losses in transmission control protocol
Wireless Networks, 2013Co-Authors: Ka-cheong Leung, C Lai, Daiqin YangAbstract:The wireless medium may cause substantial packet losses, rendering transmission control protocol (TCP) inefficient. We propose a cross-layer solution by combining link-layer retransmission techniques and a solution for TCP packet reordering. It is costly to conduct link-layer retransmission with the constraint of orderly packet delivery. We require the link layer to provide reliable packet delivery, but without orderly delivery guarantee, thus transforming the problem of high packet error rates to the problem of packet reordering. The latter is dealt with by enhancing TCP with a solution for packet reordering. We justify our design by analyzing both general scenarios and the case of IEEE 802.11n. Our simulation results demonstrate that the proposed method is effective in improving TCP connection goodput in wireless networks.

an overview of packet reordering in transmission control protocol tcp problems solutions and challenges
IEEE Transactions on Parallel and Distributed Systems, 2007Co-Authors: Ka-cheong Leung, Daiqin YangAbstract:transmission control protocol (TCP) is the most popular transport layer protocol for the Internet. Due to various reasons, such as multipath routing, route fluttering, and retransmissions, packets belonging to the same flow may arrive out of order at a destination. Such packet reordering violates the design principles of some traffic control mechanisms in TCP and, thus, poses performance problems. In this paper, we provide a comprehensive and in-depth survey on recent research on packet reordering in TCP. The causes and problems for packet reordering are discussed. Various representative algorithms are examined and compared by computer simulations. The ported program codes and simulation scripts are available for download. Some open questions are discussed to stimulate further research in this area

transmission control protocol (TCP) in wireless networks: issues, approaches, and challenges
IEEE Communications Surveys & Tutorials, 2006Co-Authors: Ka-cheong LeungAbstract:The transmission control protocol (TCP) is the most popular transport layer protocol for the Internet. Due to the characteristics specific to wireless networks, such as signal fading and mobility, packets may be lost due to con- gestive and noncongestive losses. Substantial noncongestive losses violate the design principles of some traffic control mechanisms in TCP and thus pose performance problems. In this article we provide a comprehensive and in-depth survey on recent research in TCP for wireless communications. The taxonomy and characteristics of wireless networks, and problems for TCP in wireless communications are introduced. Various representative algorithms which preserve the end-to-end semantics are examined. Some open ques- tions are discussed in order to stimulate further research in this area.

A load based transmission control protocol for wireless sensor networks
International Journal of Information Technology, 2018Co-Authors: Neelam Sharma, Karan Singh, Babita SinghAbstract:Wireless sensor network (WSN) is a hot area of research which is useful in countless applications in various fields of engineering and technology. In WSN wireless nodes are dispersed in a well confined area, and most of the times are static once they are deployed. These nodes are battery operated and their energy goes down as they transmit beacon or informative packets. In past many routing protocols are proposed which tries to minimize the energy dissipation by using various approaches. Till date in proposed protocols information is transmitted in each round, however in many applications such frequent information/update is not desirable, therefore to restrict transfer of packets in each round in this paper a load based transmission control protocol is proposed, where by varying the load, transfer of packets can be controlled, and this mechanism reduces the dissipation of energy and thus improves, stability period, network lifetime and throughput. The performance evaluation of the proposed scheme is done using MATLAB software and keys features of proposed protocol are highlighted.
