摘要:

在无线传感器网络中引入移动数据收集器(MDC)可以缓解传统静态网络能耗不均衡与能量空洞等问题。为使MDC对网络的节能效果达到最佳,通过算法设计使节点在远离或靠近sink的不同方向上拥有移动概率,在网络节点密度不同的地方建立大小各异的数据收集树平衡网络能耗,数据收集前调整收集器的位置,以减少数据传输能耗。给出MDC运动策略,并与DSDV路由协议相结合,提出带有移动数据收集器的路由协议MDSDV。实验结果表明,MDSDV能够提高网络的数据传输成功率,延长网络的生存期。

Abstract:

The introduction of Mobile Data Collector(MDC) in Wireless Sensor Network(WSN) can alleviate energy imbalances and “energy holes” problems in traditional static networks.In order to optimize the energy saving effect of MDC on the network,this paper designs algorithm to allow nodes having a probability of movement in different directions away from or near the sink,and establish data collection trees of different sizes at different network node densities to balance network energy consumption and adjust the location of collectors before data collection to reduce data transmission energy consumption.The MDC motion strategy is given and combined with the DSDV routing protocol,the routing protocol MDSDV with mobile data collector is proposed.Experimental results show that MDSDV can improve the data transmission success rate of the network and prolong the lifetime of the network.

Key words: Wireless Sensor Network(WSN), Mobile Data Collector(MDC), data collection, motion strategy, energy holes
