Efficient location management of mobile node in wireless mobile ad-hoc network

Abstract

A mobile ad hoc network (MANET) consists of a group of mobile nodes (MNs) that communicate with each other without the presence of infrastructure. The wireless mobile hosts communicate in a multihop fashion. In multi-hop wireless ad-hoc networks, designing energy-efficient routing protocols is critical since nodes have very limited energy, computing power and communication capabilities. For such protocols to scale to larger ad-hoc networks, localized algorithms need to be proposed that completely depend on local information. Hence, here introduce a protocol to handle multihop situations known as Energy Efficient Location Based Routing Protocol for MANETs (EELBR) that is based on Location Aided Routing. EELBR makes significant reduction in the energy consumption of the mobile nodes batteries by limiting the area of discovering a new route to a smaller zone. Thus, control packets overhead are significantly reduced. Developing a method to adaptively use one of the forwarding methods of the position-based routing protocol based on the surrounding environments, and dividing the network into a number of areas that varies dynamically based on the node mobility pattern. Then, show through analysis and implementation that it outperforms most of other protocols currently used in practice under various networks.
