Securing Wireless Sensor Network

Abstract

it is required to maintain privacy of critical information when it is sent over the channel. Wireless sensor network can be used in military application for detecting intrusion,enemy tracking and protection of force tracking. Wireless sensor network is made of distributed sensor nodes which are connected to each other. Nodes have limited resources for computation,transmission and other activities. But this network is vulnerable to various kinds of security threats like eavesdropping,node compromisa- tion,node capturing,man in middle attack. To ensure security of critical information over communication channel , messages must be encrypted. This scheme will use the inherent parameter of a wireless sensor network This will improve performance in terms of resource consumption for resource constrained network.
