Comparative Analysis of Routing in MANET

Abstract

Open Shortest Path First (OSPF) is a popular link state routing protocol widely used in Internet infrastructure. OSPF implements several timers to limit the protocol overhead. a link state routing protocol is a popular interior gateway protocol (IGP) in the internet. Modern routing domains need to maintain a very high level of service availability. Hence, OSPF needs to achieve fast conversance to topology changes. Also, the ever-growing size routing domains, and possible presence of wireless mobile ar-hoc components, requires a highly scalable operation on part of OSPF to avoid routing instability. Optimized link– state routing protocol (OLSR) one of the prominent routing protocols for Mobile Ad Hoc Networks (MANET). It is a pro-active protocol where nodes periodically exchanges topology information in order to establish a route to any destination in the network. In this paper we present a comparative analysis between OSPF & OLSR protocol.
