a new routing algorithm for vehicular ad-hoc networks based on glowworm swarm optimization algorithm

Vehicular ad hoc networks (vanets) are a particular type of mobile ad hoc networks (manets) in which the vehicles are considered as nodes. due to the rapid topology change and frequent disconnection in these networks, it is difficult to design an efficient routing protocol for routing data among vehicles. in this work, a new routing protocol is provided based on the glowworm swarm optimization algorithm. by using the glowworm algorithm, the proposed protocol detects the optimal route between three-way and intersections. then the packets are delivered based on the selected routes. the proposed algorithm assigns a value to each route from a source to the destination using the glowworm swarm optimization algorithm, which is a distributed heuristic algorithm. then a route with a higher value is selected to send messages from the source to the destination. the simulation results show that the proposed algorithm has a better performance than the similar algorithms.
