一种能量有效的分布式传感器管理算法
Energy efficient distributed sensor management algorithm
摘要
Abstract
Considering the limitation of energy in wireless sensor networks(WSN),a distributed sensor management algorithm is proposed for multi-target tracking with high accuracy and efficient energy conservation.The predicted coordinate of the target and information gain are used to establish the optimization model.The method introduces the auction theory and adjusts the price of the sensor resources, and once the balance of the market is reached,the target-sensor assignment problem is solved.In order to shorten the decision-making time and save the energy consumption,the carrier sense multiple access(CSMA) mechanism is introduced and the decision-making can be completed with local information and a few iterations.The convergence and effectiveness of the algorithm are proved,and simulation results show that the algorithm can effectively deal with multi-target tracking problem,guarantee the tracking performance and save the energy to prolong the network lifetime.So the proposed algorithm has a strong adaptability for the energy constrained WSN.关键词
