摘要
提出一种能量高效的数据收集和数据融合协议(CEDGAP),它基于分簇路由机制,在网络分簇形成之后加入了簇内节点度的控制机制,网络中将会产生一定数量的休眠节点和休眠区域,在数据传输阶段,这些休眠节点不发送数据,它们与处于同一休眠区域的节点在不同轮次间交替被唤醒并往簇头发送数据.文章分析了CEDGAP的影响因素以及协议的时间复杂度.NS-2仿真结果显示,与LEACH相比,CEDGAP提高了网络能耗负载均衡性能,延长了网络生命期.
Proposed a novel cluster-based energy-efficient data gathering and aggregation protocol（CEDGAP）.It is based on clustering routing mechanism;we employ the node degree control mechanism in each cluster after forming the all clusters.There are certain number of dormant nodes and dormant areas will be produced in the network,during data transmission phase,there dormant nodes do not send any data.Within the same dormant area,these nodes take turns to be woken up between different rounds and send data to the own cluster head.The influence factors of CEDGAP are analyzed,and we give the time complexity of CEDGAP.The NS-2 simulation results show that compared with LEACH,CEDGAP improves the energy consumption load balancing of the network and prolongs the network lifetime.
