Constructing a Cluster-Based Multi-hop Tree for Object Tracking in Wireless Sensor Networks

Abstract

Object tracking is an important application in wireless sensor networks. To get the accurate location of a given object timely, designing an efficient routing protocol and incorporating it with the location response is the key. While limits of wireless sensor networks propose challenge for the routing of object tracking. This paper constructs a cluster-based routing tree, which makes balance between tracking quality and energy consumption. It can provide reliable data transmission, meanwhile makes guarantee of energy savings. Finally, we validate the protocol using TOSSIM. Comparing with existing methods, our method obtains better performance in term of tracking quality and energy savings.
