SE-GPSR: Secured and Enhanced Greedy Perimeter Stateless Routing Protocol for Vehicular Ad hoc Networks

Abstract

In Intelligent Transport Systems (ITS), Vehicular Ad-hoc Networks (VANET) play an essential role in improving road safety and traffic efficiency. Nevertheless, due to its special characteristics like high mobility, large size of the network and dynamic topology make routing of data in the vehicular ad hoc network more challenging. The problem in these networks is to determine the routing protocol best suited to this environment, and then secure it to provide optimal and secure routing for the data. Recently, position-based routing protocol has been developed by researchers to be a very interesting routing technique for communication between vehicles. In this paper, we propose an secured and enhanced version of the Greedy Perimeter Stateless Routing (GPSR) protocol. This protocol consists of two modules: (i) To implement an improvement of GPSR routing protocol which minimizes transfer delays and control messages. (ii) To deal with security issues, we have proposed a solution that combines between an improved Diffie-Hellman algorithm for reliable key exchange and the hash function based Message Authentication Code (MAC) for the verification of the authentication and integrity of GPSR packet. The proposed solution was checked by the security protocol verification tool, Automated Validation of Internet Security Protocols and Applications (AVISPA), which indicated that it is a very secure level. Simulation results showed that our proposed compared to the original GPSR offers better performances.

NAV2V: Navigation Assisted V2V Routing Protocol for Urban Areas

“…These protocols must be flexible to the peculiarities and resources of VANET, where vehicles can face many obstacles, such as crossings, buildings, traffic lights, trees, resulting in insufficient channel quality and connectivity. Therefore, it is necessary to use an efficient and reliable routing protocol to have an effective communication without losing data [12]. Various systems are involved through this modern notion of VANETs, for example, areas of traffic management, routing, handover, signal propagation, autonomous vehicles, etc.…”

“…A stable and improved variant of the Greedy Perimeter Stateless Routing (GPSR) protocol is introduced by the overlay. This protocol consists of two modules that incorporate an upgrade that minimises transmission delays and message control in the GPSR routing protocol [12].…”

“…This has become a hot spot for testing, and the Greedy Perimeter Stateless Routing Protocol (GPSR), is the most promising routing protocol category using this method. It uses a traditional routing technique based on a location that uses information from nearby vehicles to determine which neighbouring node to receive the data would be chosen [12].…”

Privacy Preservation Authentication Model for a Secure Infrastructure over Vehicular Communications

“…In these networks, vehicles are equipped with wireless short and medium range communication. Actually, the vehicles can communicate with each other with two methods, either Vehicle to Vehicle (V2V) or Vehicle to Infrastructure (V2I) where vehicle communicates with the equipment next to the road named Road Side Unit (RSU) [3]. VANET are used to meet the communication needs applied to transport networks to improve driving and road safety for road users.…”

WA-GPSR: Weight-Aware GPSR-Based Routing Protocol for VANET

“…The classification of the routing protocols is according to two types: routing based on topology and geographic routing. The literature attests that geographical routing tends to be the most forceful and attractive one [4] [5]. Researchers in [6] attests that Geo-Networking has many merits and features, such as high scalability, good performance when velocity of vehcles is high and various information can be included in the status information like geographic location, time stamp, speed and exchange it via location based service.…”
