REDUCING DROPPED PACKETS OVERHEAD OF LINK STATE AWARE GEOGRAPHIC OPPORTUNISTIC ROUTING PROTOCOL FOR VANETS
Keywords:VANET, LSGO, Geographic opportunistic routing
Vehicular Adhoc Networks (VANETs) are subpart of Mobile Adhoc Network. VANETs are self-organized
wireless networks, which are infrastructure less. Due to the high mobility of VANETs and increase the speed of vehicles,
the connectivity between vehicles become poor which result in an increase the dropped packets overhead of LSGO
routing protocol. LSGO routing protocol is a combination of link state information and geographic location of nodes.
LSGO aim to improve the data transmission reliability in high dynamic environment. In this paper, we present the
method to reduce the overhead when nodes move out of range. During link failure, source node stop the packet
transmission by RERR message send by intermediate node and find another routing path from routing table and again
start transmission on new routing path.
