Abstract

Routing in Vehicular Ad hoc Networks is a challenging as the nodes keep on moving at higher speeds. This results in the topology of the network changing at faster rates. If any link made by two connecting vehicles has any one of the vehicle moving at relative faster speed as compared to predecessor vehicle, then link breakage is inevitable. This link breakage will not let the packets reach the destination node properly resulting in loss of information (throughput) as well as packet delivery ratio. This paper defines routing scheme that takes into account higher throughput and lesser end-to-end delay of the links between the nodes that constitute the path from source to destination vehicle. The performance of the network was analyzed based on three parameters namely packet delivery ratio, throughput and routing overhead in the network. These parameters have shown to outperform the existing Ant Colony Optimization technique used for routing.
