Object Location in Cluster Based Mobile Ad Hoc Networks

Abstract

Object location Services (OLS) in MANET is a challenging issue due to limitation of the applications of MANET such as bandwidth, mobility, battery power, memory etc.., For more significance and efficient results we have worked out on the clustering architecture for location services in MANET. We brief in this paper about location services in MANET. Due to frequent mobility of the mobile hosts the physical topology of the network continuously changes as result frequent link breaks of existing paths. The absence of any centralized, dedicated servers to maintain the location information of the mobile hosts in Mobile ad-hoc networks is a challenging issue. Therefore location management becomes an important issue. Location management refers to updating and searching the “whereabouts” of mobile nodes in a network. The proposed algorithm for object location in MANET using clustering has shown effective and better results when comparing with the very well known location protocol that is GLS (Grid Location Services). The algorithm also registers and updates the location information of mobile nodes as well as searches their current location in ClusterHead tables. The simulation results show that lesser overhead cost of object location and better throughput are achieved when using the clustering methodologies by implementing a mechanism to track the location of other Mobile nodes (MN) in the network topology.
