【摘要】 为延长无线传感器网络(WSN)的寿命,在传统的典型分簇算法LEACH和EADEEG的基础上进行改进,提出了一种新的基于分簇结构的数据收集协议—IDCP(Improued Data Collectiou Protocot,IDCP),在簇首形成阶段和数据转发传递阶段分别提出了新的簇首形成算法和簇内数据转发算法.在簇首形成阶段,引入对节点可靠度指标的考量;在数据转发传递阶段,所有簇内普通节点对需要转发的信息首先进行判断分析,再决定是否进行信息传递.仿真实验结果表明:与传统协议相比较,改进算法在簇首选择和数据转发上都具有更好的网络处理能力和更高的效率,有效延长了网络生存周期.更多还原

【Abstract】 In order to extend the lifetime of WSN,based on the studying of the traditional typical clustering algorithms of LEACH and EADEEG,a novel data collection protocol named IDCP is proposed by making improvement,and new clustering topology formation algorithm and new data forwarding algorithm are proposed during clustering formation and data forwarding stage.In setting stage,the introduction of the reliability index of the node is proposed.In data forwarding stage,all forwarded information is analyzed by all common nodes in clusters and the information is analyzed according to the expected value.If the analysis result is less than the expected value,information will not be transmitted,otherwise information will be transmitted.Experiments and results analysis show that,the improved algorithm considers the effects on node energy and sense reliability factor properly,it is better than the traditional algorithms in cluster head selection and data forwarding and its network processing ability and performance are both better.更多还原
