摘要:
在无线传感器网络的多跳网络模型中,越靠近基站的簇头,其转发任务越频繁,从而造成耗能更多.提出一种区域间能量均衡的无线传感器网络分簇算法EBCP,靠近基站的簇头数目增加,簇的范围减小.仿真表明其有效地解决了"热区"问题.同时引入在簇内选取多个候选簇头的机制来保证簇成员更换的频率的降低,有效地均衡与基站距离较近的簇头节点因过多转发任务带来的能量损失,从而延长了网络生命周期.
摘要(英文):
In model of multi- hop wireless sensor networks, if a cluster head is more close to the base station, it will have much more transmitting tasks, therefore a head more close by the station will consume much more energy. This paper proposed an energy-balanced Clustering Protocol in Different Zones for wireless sensor networks. In clusters closed by the base station and distributed in a small range,there are more cluster heads to be produced closer to the base station. Simulation results show that EBCP efficiently solve the "hot spot" problem. M...
