Abstract
Vehicular Ad-hoc Network inheritance ability/feature of information communication in a moving vehicle, makes it suitable to manage traffic, efficiently handle emergency situation, information sharing, and many more. VANET still has immense potential unknown areas and challenges makes it important research topic. One of the key challenges is finding a short and stable route in a short period under uncertain conditions; this is due to the high mobility of vehicle and rapid topology change. As an answer to this challenge, we propose Fuzzy Bacterial Foraging Optimization Zone Based Routing (FBFOZBR) protocol. This protocol uses three techniques. To increase stability, we used Zone Based Routing (ZBR). To find the short route in short period, we used Bacterial Foraging Optimization (BFO). To handle uncertain conditions of VANET, we used fuzzy logic. Simulation carried on FBFOZBR protocol and route performance results compared with state-of-art routing protocol PFQAODV. In the first case, we fixed the node velocity and route performance studied at the different transmission rate. In the second case, we fixed the transmission rate and route performance studied at different node velocity. Simulation showed that under uncertain conditions, the discovered route by FBFOZBR is short and stable, compared to route discovered by PFQAODV. FBFOZBR improves the performance of VANET.
