Improved OLSR Protocol for VANET

Abstract

VANET is now rapidly growing and the hot emerging research area but still it faces lots of grate challenges
on quality of service due to high mobility and limited transporting distance. The demand of multimedia data like video
streaming, listing a song, and web surfing is increasing day by day by people in the road so due to high mobility and
limited contact time between vehicles, It very challenging task in VANET to support the multimedia data and provide
quality of service for multimedia data. The performance of VANET is partly operated by the routing protocol which
determines how packets are forward from node to node. However, the rapid network topology change and the effects of
signal attenuation means that established paths do not stay valid for long and the recomputation of the path affects the
application traffic performance. Due to the rapid topological changes and provide better quality of service in VANET, we
prompted our research on reactive routing protocol OLSR. The main aim for this research to check the performance and
quality of service of Optimized Link State Routing protocol (OLSR) using bandwidth based MPR selection. OLSR is a
link state and a table driven proactive protocol which preferred owing to its multipoint relaying (MPR) feature. All the
simulation will be performed in NS2, SUMO and MOVE.
