摘　　要：在传感器网络中,对节点感应性能的衡量指标存在无明确分类和定义难以统一的问题。为解决这种感应模型设计、选择的合理性问题,从瞬时和长时两个方面对已有的各种感应模型进行分类分析,并提出一种新的瞬时感应性能模型——面向认知过程的感应模型;通过比较各种模型,得出其间的关联关系和应用特性,为进行网络拓扑和覆盖控制研究奠定基础;最后通过仿真验证了分析结论。In wireless sensor network,there are two problems,namely the indecisive classification and the disunity definition, in the measurement of sensing ability. In order to solve the problem that how to design and choose the sensing model,this paper analyzed all kinds of existing models from two aspects such as instantaneity and accumulation. And presented a novel instantaneity model： the discerning sensor model. By the comparison among models,presented their relations and the applied characters. These works lay the foundation for the study about topology and coverage control. Finally,the simulations validated the conclusion.
