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.
This paper proposes an energy efficient data collection and data fusion protocol (CEDGAP) which is based on the clustering routing mechanism and adds the control mechanism of degree of nodes in the cluster after the formation of network clustering. There will be a certain number of sleepy nodes in the network and In the data transfer phase, these sleeping nodes do not send data and they are woken up alternately with different nodes in the same sleeping area and send data to the cluster head. The paper analyzes the influencing factors of CEDGAP and the time complexity of the protocol Degree.NS-2 simulation results show that compared with LEACH, CEDGAP improves network load balancing performance and prolongs network lifetime.
