Performance analysis of Geocast based location aided routing using Cache agent in VANET

Abstract

Vehicular Ad hoc Networks (VANET) is a self-organizing communication network which built over mobilized vehicle. Finding and maintaining the route for sending any information is a challenging task. In this paper a hybrid routing protocols called Cache Agent based Location aided routing using distance and direction (CALAR-DD), Cache Agent based Location aided routing using direction (D-CALAR) and Fuzzy assisted Location Aided Routing using Cache (FLAR-C) were analyzed in term of performance. D-CALAR, CALAR-DD and FLAR-C protocols were fusion of Geocasting approach and Location Aided routing protocol. The D-CALAR, CALAR-DD and FLAR-C where deployed and implemented for City environment. This paper implements D-CALAR, CALAR-DD and FLAR-C for highway as well as city vehicular environment. An experimental study is carried out with 200 nodes and evaluated with performance metrics. Average hop count, packet delivery ratio, average delay, re-transmission ratio, throughput and packet lost ratio are used to evaluate D-CALAR, CALAR-DD and FLAR-C routing protocols performance analysis in VANET.
