【 摘 要 】

The recent advancements in the field of wireless communication have enabled some wireless networks tobecome of highly dynamic in nature, like Vehicular Ad hoc Networks (VANETs). This emergence of specialisednetworks involves high relative node velocity and high active node density. Such complexities demand moreefficient and intelligent routing techniques. Anefficient routing algorithmfinds thebest possible route withminimum overhead, updatesiton availability of a better one and then maintainsroutein case of link breakages.Many routing protocols focus on finding and maintaining efficient routes, whereas very less emphasis is put onroute update. We have evaluated some existing route updating techniques, which are based on periodic, eventtriggered or flow based routing information sharing schemes. The evaluation shows that current routing metricsharing schemes do not perform well under varying network scenarios. Subsequently, a model is proposed foradaptive route update of dynamic networks. From theoretical analysis and simulation, the results show that theproposed adaptive route update approach is applicable to a number of routing strategies. The proposedadaptive strategy for routing information sharing is not restricted to any specific routing approach and canenhance the efficiency of routing protocols in varying network conditions.
