A network coding based multicast routing in mobile AD-HOC wireless networks

Abstract

Nowadays, network coding is an emerging approach used to increase network throughput. However, in mobile ad-hoc wireless networks, due to dynamic network topology, it is difficult to make coding decision at intermediate nodes. In this paper, we discuss how to increase coding opportunities and the challenges of network coding in mobile ad-hoc wireless networks. From those issues, we propose a Network Coding based Multicast Routing, called NCMR, in mobile ad-hoc wireless networks. NCMR is especially well-suited for providing reliable, high speed multimedia applications. In our study, the performance of our proposed NCMR is evaluated in terms of packet delivery ratio, end-toend delay, network congestion via different scenarios by using OPNET. © Springer-Verlag Berlin Heidelberg 2014.
