Optimized Link State Routing - A Review

Abstract— The security provisioning for routing in Mobile ah-hoc Networks (MANET) is a significant challenge to address. Various protocols have focused to maximize network lifetime by managing topology information in efficient manner. An Optimized Link State Routing Protocol known as OLSR is presented in literature which is adaptive to the energy consumption resulting in longevity of lifetime of the network without compromising the performances like throughput, endto- end delay or overhead. OLSR experiences less delay to find a route due to its proactive nature with the expense ofresources. This paper reviews research carried out on the extensions of the OLSR protocols to scale well with dense network as well to handle security threats as MANET is more vulnerable to various kinds of attacks.
