OPTIMIZING COST AND THROUHPUT EFFICIENCY WITH SECURITY IN WIRELESS AD HOC NETWORKS USING LEACH

Wireless ad hoc network (WANET) is a decentralized type of the wireless network. There are various challenges that are faced in the ad hoc environment. Wireless ad hoc networking is the enabling technology for paramount civilian and military applications requiring easy and quick (and often unmanned and cheap) network deployments. The security of communication in ad hoc wireless network is very important especially in military applications. The wireless nature of communication and any lack of network security infrastructure raise several security problems. Asymptotic notations solve the problem of large wireless networks. The main objective of the system is performance degradation of the secure network. In this paper mainly considering, order to reduce delay and increase throughput. The network performance can be calculated by using probability (p<1). Here we implemented LEACH algorithm for an efficient energy saving and thus increases the life time of wireless network. The simulation results show the presented algorithm is more efficient energy saving and fewer packets are damaged; thus provides secure wireless network. (c) 2012 Published by Elsevier Ltd.
