A Research of Sensors Complementary for the RFID Wireless Network based on the Variable Coverage Radius

In order to solve the problems of sensors complementary, algorithm sensors complementary for the RFID wireless network is proposed in this paper. Based upon the fundamental definitions about the probabilistic events and the data generated by the particle filtering algorithm, the paper considers the factors of the number of locations covered and the probability the object appears. In view of the definition of the covering variability and the cover ratio, 5kinds of RFID sensors covering radius are considered. Finally, the experiment is carried out in order to improve the algorithm’s availability and effectiveness.
