    摘要:

    针对长距离带状无线传感器网络的能耗不均、易出现“热区”等问题,本文提出一种适合长距离带状无线传感器网络拓扑结构的能量高效的路由协议ERPLDB。ERPLDB协议通过网络能耗模型中的能量消耗公式计算出各个簇的网络节点平均能耗, 并使各个簇内的网络节点平均能耗近似相等来进行非均匀分簇,使越靠近Sink节点的簇规模越小,从而有更多的能量转发远程簇传输过来的数据,尽量减少“热区”问题的出现。仿真结果表明,本文提出的ERPLDB协议能均衡长距离带状网络的能量消耗、有效延长网络的生命周期。

    Abstract:

    To solve the problems of uneven energy consumption, prone to "hot zone" etc. in long distance band-type wireless sensor network, a energy-efficient routing protocol for long distance band-type network ( ERPLDB ) is presented in this paper. In ERPLDB, average energy consumption of each cluster in the network is calculated according to the energy consumption formula of the network energy consumption model. And the network is uneven clustered by equaling average energy consumption of each cluster. Then more close to the sink node, smaller the scale of the cluster. So the cluster more close to the sink node can save more energy to forward data coming from the more distance cluster. And the "hot zone" problem is solved effectively. Simulation results show that ERPLDB can balance the long distance band-type network energy consumption, effectively extending the life of network.
