SCHC: Generic Framework for Static Context Header Compression and Fragmentation
2020Co-Authors: Ana Minaburo, Laurent Toutain, Carles Gomez, Dominique Barthel, Juan Carlos ZunigaAbstract:This document defines the Static Context Header Compression (SCHC) framework, which provides both a header compression mechanism and an optional fragmentation mechanism. SCHC has been designed for Low Power Wide Area Networks (LPWAN). SCHC compression is based on a common Static Context stored both in the LPWAN device and in the network infrastructure side. This document defines a generic header compression mechanism and its application to compress IPv6/UDP headers. This document also specifies an optional fragmentation and reassembly mechanism. It can be used to support the IPv6 MTU requirement over the LPWAN technologies. Fragmentation is needed for IPv6 datagrams that, after SCHC compression or when such compression was not possible, still exceed the layer-2 maximum payload size. The SCHC header compression and fragmentation mechanisms are independent of the specific LPWAN technology over which they are used. This document defines generic functionalities and offers flexibility with regard to parameter settings and mechanism choices. This document standardizes the exchange over the LPWAN between two SCHC entities. Settings and choices specific to a technology or a product are expected to be grouped into profiles, which are specified in other documents. Data models for the Context and profiles are out of scope.

IPv6 over LPWANs: Connecting Low Power Wide Area Networks to the Internet (of Things)
IEEE Wireless Communications, 2020Co-Authors: Carles Gomez, Laurent Toutain, Ana Minaburo, Dominique Barthel, Juan Carlos ZunigaAbstract:LPWANs have recently emerged as a promising solution for enabling industrial IoT applications. To fully exploit their potential, LPWANs need to be connected to the Internet. However, the severe capacity constraints of LPWAN technologies challenge IPv6 support, and even 6LoWPAN-based adaptations are not sufficient. In this paper, we present Static Context Header Compression and Fragmentation (SCHC), an ultralightweight IPv6 adaptation layer designed for LPWANs, which is being standardized by the IETF.

SCHC-Based Solution for Roaming in LoRaWAN
Advances on Broad-Band Wireless Computing Communication and Applications, 2020Co-Authors: Wael Ayoub, Mohamad Mroue, Abed Ellatif Samhat, Fabienne Nouvel, Jean-christophe PrévotetAbstract:To take advantage of IPv6 stack in IoT technologies, an efficient header compression scheme is required. Since 2004, many IPv6 header compression schemes have been proposed and some of them have been standardized by the IETF. In [ 9 ], Static Context Header Compression (SCHC) mechanism has been designed for Low Power Wide Area Networks (LPWAN). SCHC compression is based on a common Static Context stored in both the IoT device and the network side. This Static Context defines the compression and decompression rules of the headers. The SCHC framework is compatible with LoRaWAN v1.0 [ 2 ] but not with LoRaWAN v1.1 that supports roaming of devices during mobility between different LoRaWAN operators. During roaming, the header values of the protocol stack change and are no longer Static. In this paper, we propose a solution based on SCHC to support roaming of devices during mobility between different LoRaWAN operators. We define a server to manage the Context between operators. In addition, the LoRaWAN frame route and the communication scheme are updated. A testbed has been setup to show the time differences between current LoRaWAN network and our proposal. The results shows that our proposal improves the communication process and decreases the time delay to handle the transmitted messages “uplink” before the registration.

Mobility Management With Session Continuity During Handover in LPWAN
IEEE internet of things journal, 2020Co-Authors: Wael Ayoub, Mohamad Mroue, Abed Ellatif Samhat, Fabienne Nouvel, Jean-christophe PrévotetAbstract:In this article, we consider the mobility of an end device (ED) in low-power wide-area networks (LPWANs) and we focus on the continuity of the ED session with the application server when this ED is moving from the coverage of one operator to that of another one. One of the methods to achieve the continuity of the session after roaming is the use of an IPv6-based scheme. As LPWAN is characterized by a fixed message rate and very small bandwidth as well as asymmetric communication, an efficient header compression scheme is required. Recently, the Internet Engineering Task Force LPWAN working group has proposed a Static Context header compression (SCHC) to compress IPv6 into LPWAN through a rule-based mechanism. In this article, we first extend the SCHC scheme to support session continuity and the new scheme is called mobile SCHC (MSCHC). MSCHC consists of several Contexts, instead of the Static Context for SCHC and we also improve the use of the memory by dividing the rules into layers. Then, we investigate the mobility of the ED to show how the continuity of the session can be achieved while transmitting and receiving data when the ED is roaming between different operators. The proposed solution is based on the use of light mobile IPv6 messages compressed with MSCHC. Finally, the proposed mechanism is implemented in the popular LoRaWAN technology, evaluated and compared with the existing solutions provided by the LoRaWAN v1.1 standard.
