| 摘 要： | 无线传感器网络是由能够感知环境信息和能够进行无线通信的传感器节点构成的网络,广泛应用在环境监测、目标跟踪等方面.无线传感器网络中,汇聚节点(Sink)的位置选取关系到整个网络的性能和生命期,并与节点的部署情况、网络的拓扑结构紧密关联.本文对汇聚节点位置对于无线传感器网络性能和生命期的影响进行了分析之后,以全网能耗、平均-最大端到端延迟为权衡指标,设计了汇聚节点选举协议.仿真表明,运行该协议的网络能够以较小的代价,迅速地选举出具备最优权衡指标的Sink,同时网络还体现出优秀的自组织组网能力.

| Abstract: | Wireless sensor networks(WSN) consist of a lot of sensor nodes,which can sense the environment and communicate using wireless link.It is widely used in environment observation and object tracking.In WSN,the position of sink node is related to the per-formance and life-time of the network,and is tightly bond up with the deployment and topology of it.How the position of sink effect the performance and life-time of WSN is analyzed.In addition,a sink election protocol is proposed to improve the total energy consumed index and network life-time index.The simulation illustrates that,WSN running the protocol can rapidly vote a sink which has the best mixed index at low cost.And it also has a perfect ability of self-organizing. |
