Then a binary awareness model based on stochastic sensor placement and a stochastic multi-objective PSO arithmetic based on binary system which is applied on awareness model have been present. The simulation results indicated that stochastic multi-objective PSO arithmetic is able to optimize the nodes coverage fleetly and efficiently. On the premise of the acquisition of a same network coverage and nodes utilization ratio, stochastic multi-objective PSO arithmetic is more rapid than genetic algorithm in convergence.This thesis has also introduced a rising technology of wireless sensornetwork--ZigBee technology. After researching and analyzing the ZigBee protocol,this thesis has described the design of the PHY and MAC layers in detail. Then the paper has chosen a ZigBee's hardware scheme CC2430/CC2431 which is offered by Texas Instruments Company to design a mine tunnel localization system based on ZigBee network. At last, the thesis has experimented a simple indoor wireless localization test utilizing ZigBee's hardware platform. And the theoretical feasibility of ZigBee technology in the application of real-time wireless localization through the short distance of a mine tunnel is validated.
