Target counting algorithm via local signal recovery in sensor networks

Abstract

In view of the deficiencies of existing targets counting algorithms in sensor networks,a local signal recovery based target counting algorithm(LSR)was proposed.LSR firstly searched for the possible local area where targets may exist,and then established a local signal recover model according to signal attenuation characteristic and nodes' distribu-tion.Finally,LSR sought the best target distribution estimation in each possible local area through the established model and obtained the target counting result by summarizing the estimations.Simulation results demonstrate that LSR pos-sesses good merits in counting precision,noise tolerance and energy consumption.
