Investigation and analysis of AODV routing protocol for minimizing end to end delay and improving packets delivery ratio based on clustered fuzzy reputation mechanism in mobile Ad Hoc networks

Abstract

Wireless networks are increasingly becoming popular and have enabled communication between mobile devices using standard network protocols In ad hoc networks nodes communicate directly with each other without any special access point equipment Because of its infrastructure less feature ad hoc wireless networks can be used when the mobile devices are on the move even in places where access points are not feasible In an ad hoc network connectivity is achieved in the form of a multihop graph between the newlinenodes The QoS of the network depends on the terminal position coverage pattern and transmission power and interference level Unlike wired networks the topology may change continuously and hence the QoS parameters also change dynamically As the topology is dynamic planning the configuration of MANET is challenging and difficult The network should be capable to reconfigure itself based on the dynamic nature of the terminals and based on application it is running along with the protocols used AODV has been found to be highly efficient in medium sized networks with moderate mobility Though the network characteristics make it more susceptible to attack and lower the performance This research investigates performance of AODV routing and proposes improvements newline newline
