Energy Efficient Trustworthy Target Tracking Scheme (3TS) based on Clustering and Task Cycle Scheduling for Wireless Sensor Networks

Abstract

– One of the notable uses of Wireless Sensor Networks (WSN) is target detection and tracking. The primary objectives of a target tracking system are to improve target tracking precision and network longevity. This paper presents a Trustworthy Target Tracking Scheme (3TS) for WSN. The entire network region is divided into several grids of equal size, with each grid functioning as a cluster. All the grids include the same number of nodes. A Cluster Head (CH) node is selected for each grid based on the level of trust. The CH node determines the minimum number of active nodes per grid and regulates node activity. Together with the active nodes, the CH node identifies and tracks the target. In addition, the CH node informs the surrounding clusters that the target may cross. This concept enhances the accuracy of detection. Utilizing task cycle scheduling and a clustering approach, this work significantly increases the network's lifespan. The performance of the suggested work is justified in terms of detection accuracy, energy consumption, and network lifetime. The experimental findings demonstrate the effectiveness of the proposed method.
