摘要/Abstract

摘要： 提出了一种基于被动分簇算法的能源有效无线传感网络模型。该模型采用被动分簇策略，即仅当网络中有数据通信要求时才在网络中建立分簇网络拓扑，而且网络拓扑的建立与维护都在本地完成，不需要单独的控制命令以节省能量开销。分簇策略簇首选举采用“先声明者胜”的选举机制，网关节点选择依据网络健壮性和能源有效性之间平衡的原则来确定。详细地描述了网络模型的建立和维护过程，并在NS2上仿真了该模型用于定向扩散路由协议时的能源有效性。实验结果表明，使用该模型后的定向扩散路由比没有采用前具有更好的能源有效性。而且在节点大规模增加时，仍然具有良好的性能。

Abstract: An energy-efficiency WSN（Wireless Sensor Network）is presented.The model based on passive clustering strategy creates its network topology only when there are data-requests in WSN.The creation and maintenance of the topology are both local-happen and need no extra control commands，which results in energy saving.In this clustering strategy，the selection of cluster head takes a mechanism named “first declaration wins” and the gateway node is selected according to the rule that makes trade-offs between the network robust and the energy-efficiency.The creation and maintenance of the clustered network are described in detail in this paper.We also simulate the model in NS2，the results show that directed diffusion routing which adopted the model is more energy-efficient than which don’t adopt it and has a good performance even when the number of nodes increased in large scale.
