Target Tracking in Wireless Sensor Network

Abstract

With increasing advancement and popularity of wireless sensor networks, their applications in different areas are becoming more and more sophisticated. As wireless sensor networks and its components are distributed in nature, easy to configure, flexible to deploy and less costly, they are considered feasible to collect, process and store data from different terrains. Amongst multiple applications of wireless sensor networks, tracking a particular object is one of the most important ones. While tracking an object, its geographical location is determined and then constantly monitored. Every sensor in the wireless sensor network participates in sensing the position of the object being tracked, and shares this information with other components of the network. In recent years much work has been done regarding target tracking in wireless sensor networks and many algorithms have been proposed to perform the task most efficiently and optimally. In this thesis a simple approach is used to track a target which significantly improves the accuracy and other network performance parameters by minimizing the communication overhead.
