BMRRP- Block Mesh Reliable Routing Protocol for Vehicular Ad hoc Networks

Abstract

Vehicular Ad hoc networks (VANETs) are special kind of wireless adhoc networks that aim to establish communication between vehiclesand road side units. In order establish path between source and destination the intermediate nodes are used that carry data packets .However existing approaches choose nodes based on velocity, position and direction of vehicles, Due to the dynamic nature of the vanets, thenode links will not remain constant which affects reliability of network .Our proposed Block Mesh Look-up approach focuses on finding nodes with maximum stability which in turn used as co-operative nodes to improve transmission reliability, packet delivery ratioand to reduce end to end delay. Simulation and experimental results shows that block lookup approach improves the performance in terms of end-to-end delay and throughput.
