Target tracking solution for multi-sensor data fusion in wireless sensor networks

Abstract

Wireless sensor networks are often composed of many sensor nodes, they are powered by batteries with limited capacity. The sensor nodes are randomly scattered within in the ranger monitoring and send – receiver data using radio waves. Many research projects had demonstrated the consumption of battery power by the data transceiver occupy large compared to the calculation on the sensor node. In this paper, we propose energy saving solutions of nodes in a cluster by only choosing some nodes in the cluster to track the target and transmit this data to cluster head nodes. We based on the location of the sensor nodes in the cluster compare with the location of target and cluster head nodes to perform this selection. The effectiveness of the proposed solutions will be evaluated based on the number of sensor nodes are selected considering the number of nodes in the cluster, this  is the base for the effectiveness of energy saving as well as the cluster nodes.
