| 摘 要： | 在无线传感器网络中,传感器节点往往采用多跳的方式进行数据传输,造成了基站sink周围节点能量消耗过快,易形成能量空洞问题。针对这个问题,提出了一种改变中继节点能量的能耗均衡策略,即将中继节点的能量加大为原传感器节点能量的数倍,同时减少中继节点的数量。理论分析和仿真结果表明,这种方法有效地解决了能量空洞问题。考虑到成本和数据冗余问题,在中继节点数为理想数目的3/5时,网络能耗没有太大的提高,即放置少量的中继节点也能达到能耗均衡的目的。

| Abstract: | In wireless sensor networks,sensor nodes use multipoint-to-point to transmit data. The closer to the sink,the quicker they will consume its battery,which forms the energy hole problem. To this problem,an energy consumption balance strategy,changing relay-node energy,is proposed,that is increasing energy of relay-nodes,and decreasing the number of relay-nodes. Theory analysis and simulation results indicate that this method can solve energy hole problem effectively. Moreover,for the cost of nodes and data re... |
