A Novel Routing Protocol for Target Tracking in Wireless Sensor Networks

Wireless sensor networks (WSNs) are large scale integration consists of hundreds or thousands or more number of sensor nodes. They are tiny, low cost, low weight, and limited battery, primary storage, processing power. They have wireless capabilities to monitor physical or environmental conditions. This paper compared the performance analysis of some existing routing protocols for target tracking application with proposed hierarchical binary tree structure to store the routing information. The sensed information is stored in controlled way at multiple sensor nodes (e.g. node, parent node and grandparent node) which deployed using complete binary tree data structure. This reduces traffic implosion and geographical overlapping. Simulation result showed improved network lifetime by 20%, target detection probability by 25%, and reduces error rate by 20%, energy efficiency, fault tolerance, and routing efficiency. We have evaluated our proposed algorithm using NS2.
