An Improved OLSR Protocol for Reducing the Routing Overhead in MANETs

Padmavathi.K, Thivaharan.S

Manets consists of collection of nodes which can move freely. The communication in manet is done via a wireless media. Due to high mobility in manets, there exist frequent link breakages which lead to frequent path failures and route discoveries. Due to demanding real timjnie multimedia applications, quality of services (qos) support in such infrastructure less networks have become essential. Qos routing in mobile ad-hoc networks is challenging due to rapid change in network topology. The purpose of this paper is to provide a better quality of the package delivery rate and the throughput, that is in need of powerful routing protocol standards, which can guarantee delivering of the packages to destinations, and the throughput on a network. We focus on the inaccuracy of state information, more specifically the residual energy level of nodes that is collected by the control messages of olsr. Inaccurate information affects the efficiency of olsr protocol. We study some parameters of olsr that forces the inaccuracies in the energy level information of neighboring nodes and show the comparison between ideal and realistic version of olsr. Our study concluded that tuning of olsr improves the residual energy information of nodes and simulation results demonstrated a significant improvement in the criteria of package delivery rate and throughput.
