Fuzzy Logic-Based Multi-Hop Directional Location Routing in Vehicular Ad-hoc Network

A vehicular ad-hoc network (VANET) is an autonomous system of mobile vehicles created on-demand where vehicles can send or receive data packets over wireless links. In VANET, vehicles have limited communication range R and can communicate directly with neighbor vehicles. Vehicles are equipped with the short communication range dedicated communicative device, global positioning system and other computing devices. Links among vehicles break frequently due to the highly movable nature and limited communication range which turns into data delivery failure. To overcome data delivery failure in multi-hop routing, a novel routing model namely fuzzy logic-based multi-hop directional location routing (FLMDLR) in the vehicular ad-hoc networks has been developed. Using the concept of fuzzy logic, FLMDLR selects remarkable next-hops which help to establish a stable route from the source S to destination node D. Research work done in this paper has shown fuzzy logic applications are more useful to deliver data packets from node S to D. FLMDLR has simulated through network simulator-2 to evaluate performance in term of the link duration, next- hop distance, average number of next-hops, and one hop delay. Through simulated result has shown the proposed model FLMDLR perform better as compared to existing directional-location aided routing (D-LAR) and location aided routing (LAR) protocols.
