ENHANCED ROUTE SELECTION APPROACH OF GPSR USING MULTIPATH FORWARDING IN VANET
Main Article Content
Abstract
The Vehicular Ad-Hoc Network is infrastructure less network in which vehicles are connected without wires. Routing in Vehicular Ad-hoc Network is challenging nowadays due to increased no of a vehicle, the high mobility of nodes, dynamically changing topology and highly partitioned network, so the challenges on the roads are also increased like roads are full, the safety problem, speed etc. GPSR is a position based algorithm. GPSR uses source node and destination node’s position to forward packets. This protocol uses Greedy Forwarding and Perimeter Forwarding strategies for packet forwarding from source to destination. The proposed system uses the modify beacon packet strategy which includes source node and destination node parameters to route packet. All nodes are initially selected as forwarding node which is a letter on reduced to final routing path after acknowledgment. The proposed system improves the parameters like Packet Delivery Ratio and maintains a number of hop counts.
