Abstract

Recent advances in micro electro mechanical systems (MEMS) and wireless communication technologies are responsible for the emergence of Wireless Sensor Network (WSN) that deploys thousands of low-cost sensors integrating sensing, processing and communication capabilities. It motivated the use of mobile sensor node in WSNs for many surveillance applications including mission-critical target tracking. One of the most attractive areas is exploited to be the mobile target tracking. Typical examples include establishing survivable military surveillance systems, environmental and industrial monitoring, personnel and wildlife monitoring systems requiring tracking schemes, capable of deducing kinematic characteristics such as position, velocity, and acceleration of single or multiple targets(J. Janssen, et al, 2008) of interest (T.He, et al, 2006). For the above observations, the possible existence of targets can be inductively described as the Fig.1 shows for simplicity.
