Comparison between node sensing models and relative works in wireless sensor networks
传感器网络中节点感应模型与相关工作的比较*

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.
