| 摘 要： | 针对在无线传感器网络中节点能量有限的特点,提出一种基于簇的能量高效数据收集协议CEDGP(Cluster-based Energy-efficient Data Gathering Protocol).该协议首先利用相关性对网络分簇;然后利用改进的最近邻居算法构建簇内的数据收集链路;最后将收集到的数据通过多跳方式传送至基站。仿真表明该协议比传统的基于簇的协议具有更好的能量效率和更长的网络生存期。

| Abstract: | Based on the strict energy limitations in wireless sensor networks,a cluster-based,energy-efficient data gathering protocol（CEDGP） was presented.Firstly,CEDGP divided nodes in the network into clusters by the correlation.Secondly,a chain was formed in each cluster by an improved nearest neighbor algorithm.Finally,the multi-hop scheme was used to transmit the gathered data from clusterhead to the base station.The simulation results show that CEDGP can outperform PEGASIS and LEACH in terms of network lifetime and energy consumption. |
