ABSTRACT

Energy-efficient MANET routing protocol OSLR is widely used for routing in ad hoc networks. Residual energy of nodes play a vital role in route discovery in MANET. To support energy-efficient routing, accurate state information about energy levels of nodes should be available. But due to bandwidth constraints, communication costs, high loss rate and the dynamic topology of MANET, collecting and maintaining up-to-date state information is a very complex task. 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 effect 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 does not really improve the residual energy information of nodes. And finally try to suggest some techniques to reduce inaccuracies.
