A Secure Node Management Distributed Services Model for RSU Supported VANET

Vehicular Ad hoc Network (VANETs) is a sub class network of Mobile Ad hoc Network (MANETs). It has similar behavior as MANETs but different in mobility of nodes and their nodes speed. The mobility of nodes in VANETs organized in fixed pattern and speed of nodes is very high. Basically here VANETs vehicles can communicate to other vehicles directly or via intermediate fixed architectures. Most of time on highway or rural area the density of vehicles varies a lot and if any vehicle wants communicate with other vehicle directly may faces many problems. To overcome these problems the intermediate infrastructure needs to pay a very important role. In this thesis we analysis the performance of different placement strategies called DSR, AODV protocols which are traditional ones used to provide infrastructure based relays which is called as RSU (Radio Station Unit) with mobile vehicle nodes, which has been implemented using our proposed algorithm called Secure Node Management (SNM) to find that the case when RSUs are placed at both side of road with increasing mobile vehicle nodes has better performance in comparison to other. The simulation is done by using NS2 Simulator.
