Abstract: The target search problems in the wireless sensor networks are analyzed and a comparison of several existing search strategy is given.It is very important to focus on the optimal search theory in search of targets.In this paper,a novel local search optimal model is proposed.The basic detection function in the new model is improved.The parameters are an important supplement and improvement based on the actual sensor networks for large-scale in detection function.Compared with the previous search technology,new search optimal model proves its advantage in large-scale wireless sensor networks.

Key words: optimal search theory, optimal local search, wireless sensor networks

摘要: 深入分析无线传感器网络中的目标搜索问题,比较了现有的几种搜索策略,重点关注最优搜索理论在无线传感器网络目标搜索中的应用。针对大规模传感器网络,提出了局部最优搜索改进模型,新模型在基本探测函数基础上,针对大规模传感器网络实际,对参数进行了重要补充与完善,使得改进后最优搜索模型在与改进前的最后搜索比较中显示出较明显的优势。
