【摘要】 提出一种能量自适应的簇首选择机制.算法通过综合考虑候选节点的剩余能量级、通信能量损耗等参数来优化簇首的选择,从而有效地避免了低能量节点被选为簇首的可能性,进一步保证网络内节点能量负载的均衡性.仿真结果表明,改进的簇首选择机制能够很好地均衡网络能量损耗分布,有效延长近30%的网络生存时间.*更多还原

【Abstract】 This paper proposes an energy-adaptive clusterhead selection algorithm,in which additional parameters including the remaining energy level of candidates and their energy cost for transmission are synthetically considered to optimize the process of cluster-head selection.The main idea of our algorithm is to avoid choosing nodes with lower residual energy as cluster-heads,thus to ensure balanced energy-usage among the nodes in the network. Preli-minary simulation results show that our protocol greatly improves the performance and efficiently prolongs the network(lifetime) by about 30%.更多还原
