| 摘 要： | 为了提高传感器节点的能量利用效率,延长系统的生命周期,针对LEACH协议在簇首选择策略上存在的不足,提出了一种新型的簇首选择机制LEACH-TE.该算法在重新计算最优簇首数的基础上,通过综合考虑节点的剩余能量和网络的平均能量等因素来优化簇首的选择.仿真实验结果表明,改进后的协议在延长网络生存时间、降低网络能耗和提高基站接收的数据量3个方面均表现出较好的性能.

| Abstract: | To improve the energy efficiency of sensor nodes,and prolong life cycle of the system,according to the deficiency of cluster heads selection strategy in LEACH protocol,a novel selection mechanism is proposed by taking into account factors like the residual energy of nodes and the average energy of the network in algorithm to optimize cluster heads selection on the basis of recomputing the optimal number of cluster heads.Simulation results show that the improved protocol has desirable performance in prolonging network lifetime,reducing energy consumption and improving data reception of the base station. |
