GEOGRAPHICAL ROUTING PROTOCOLS FOR MOBILE AD HOC NETWORKS - A SURVEY ON THEIR PERFORMANCE ANALYSIS

R Suma, B G Premasudha

Abstract: Mobile Ad Hoc network is an autonomous system of mobile nodes connected by wireless links forming a temporary network without the aid of any centralized administration or infrastructure. Each node operates not only as an end system but also as a router to forward packets. The nodes are free to move themselves into a network. These networks have no fixed topology due to the high degree of node mobility. To accommodate the changing topology, special routing protocols are needed. The goal of the routing protocol is to have an efficient route establishment between a pair of nodes, so that messages can be delivered in a timely manner. Mobile Ad Hoc routing protocols are divided into Flat routing, Hierarchical routing, Geographical routing, Power aware routing and Multicast routing. It is difficult to determine which protocols may perform well under a number of different network scenarios. This paper provides an overview of geographical routing protocols proposed in the literature and performance comparison of geographical routing protocols.

Keywords: Mobile Ad Hoc Network, Geographical Routing protocols.
