能量有效的无线传感器网络数据收集协议

针对无线传感器能量有限问题，提出能量有效及均衡的数据收集协议(EEBDGP)。利用移动Sink(MS)进行实时数据收集，采用主动重定位MS靠近数据流量大的邻居区域的方法，缩短大流量数据的传输路径，降低传感器节点能量消耗。在数据流量相对均匀而MS的数据转发节点能量低于阈值时，MS移向能量最大的邻居节点，使传感器节点能量消耗达到均衡。实验结果表明，EEBDGP能量有效且能量均衡，并能延长网络生命期。

Energy Efficient Data Gathering Protocol for Wireless Sensor Networks

Aiming at energy limited problem of wireless sensor networks,this paper proposes an Energy Efficient and Balanced Data Gathering Protocol(EEBDGP).The protocol uses the Mobile Sink(MS) to collect data,it progressively relocates the MS closer to the regions that produce higher data rates and reduces transmission path of large data flow,enabling energy savings.When the data flow is even among the neighbors and the energy of MS's forward node is less than a threshold,MS moves to the adjacent node with the large...
