An adaptive hello interval for AODV through ANFIS to improve the performance of MANETs

Abstract

Mobile Ad Hoc Network is an easily deployable wireless network without any need of centralized infrastructure. The change of position by wireless devicesleadstolinkfailuresandroutefailures.The mobile nodes sent hello messages at regular intervals to update the status of their neighbors. Increasing the number of periodical notifications such as hello messages will give an idea about the topology and at the same moment consumes more network resources. Reducing these periodic notifications results in discovering the neighbors at veryslowrate.Thereforetherateofhellomessages has most significant role while considering the performance of MANETs. Routing Protocols such as AODV in MANETs performs the operation basing on static hello interval. In this paper an adaptive hello interval approach is proposed based on a soft computing technique “Adaptive Neuro Fuzzy Inference system” for in MANETs. The result states that the proposed solution yields a great improvement over the traditional protocol “AODV”.
