多传感器分配是传感器网应用过程中的一个关键问题，文章对多种方法进行了分析比较，指出了各种方法的优缺点及适用场合，值得借鉴-Sensor deployment is a fundamental issue in sensor

networks. Studies on the deployment problem are concentrated

on deploying sensors to cover assigned areas or set ofpoints

efficiently. In this paper, we discuss the sensor deployment

problem in the conte-xt of target tracking. Firstly, we propose a

sensor deployment optimization strategy based on Target

Involved Virtual Force Algorithm (TIVFA). The TIVFA

algorithm can dynamically adjust sensor networks configuration

according to terrains, intelligence and those detected

maneuvering targets in order to improve coverage and detection

probability. Secondly, we present an improved sensor-ranking

algorithm as well as a sensor protecting strategy with targets

importance sequence in consideration. The 7TVFA algorithm,

together with the sensor protecting strategy, can produce an

efficient and robust sensor network. Experiment results

sufficiently demonstrate the effectiveness of the proposed

approach.
