A Survey of Enhanced Routing Protocols for Manets

Abstract

Mobile Ad Hoc Networks (MANETs) form a class of dynamic multi-hop networks consisting of a set of mobile nodes that intercommunicate on shared wireless channels. MANETs are self-organizing and self-configuring multi-hop wireless networks, where the network structure changes dynamically due to the node mobility. There exists no fixed topology due to the mobility of nodes, interference, multipath propagation and path loss. Hence efficient dynamic routing protocols are required for these networks to function properly. Many routing protocols have been developed to accomplish this task. In this paper we survey various new routing protocols that have been developed as extensions or advanced versions of previously existing routing protocols for MANETs such as DSR, AODV, OLSR etc.
