A Network Coding-Aware Directional Broadcast Routing Scheme for VANET

Abstract

Abstract. Recent technological advancements in wireless communications are fundamentally changing the manner by which devices communicates with one another. Modern wireless devices build networks on their own and aid each other in passing information to any device in the network. The aim of this research is to design and develop a robust routing protocol using network coding technique for Vehicular ad hoc networks (VANET). The purpose of the protocol is to disseminate vehicular traffic to the vehicles approaching the problem area, rather than those leaving the problem area. The designed protocol during the research will be more robust, reliable, and efficient with topology change. In this research, network coding and geographical routing models will be used to develop network coding based VANET routing protocol for alerting vehicles approaching the accident area and emergency message dissemination. The network coding model assumed will serve to increase throughput, in this sense reducing packet loss which will provide a robust broadcast routing protocol.

QoS‐aware broadcasting in VANETs based on fuzzy logic and enhanced kinetic multipoint relay

“…We denote normalized number of nodes (NnN j ), the number of j's neighbors with [t from , t to ] ⊂ [T from , T to ]. Then, the expression of CKD becomes as in (2).…”

“…On the other hand, the fast expansion in wireless communication technologies has led to the development of vehicular networks related services accessible by such networks. Actually, VANET provides a wide variety of services mainly classified into three categories: safety, traffic management, and infotainment services . However, many challenges meeting the vehicular networks advances are a close consequence of special features that characterize this kind of networks such as high speed, dynamic topology, and frequent link breakage.…”
