摘要:
由于传感器节点电池电量有限，因此在无线传感器网络中如何节能是一个关键问题。对经典的LEACH（Low Energy Adaptive Clustering Hierarchy）协议做出改进：提出了一种新型的簇首选择机制。算法通过综合考虑候选节点的剩余能量、地理位置等参数来优化簇首的选择，从而有效地降低了低能量与位置不佳的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，新型的簇首选择机制能够有效平衡节点的能量消耗分布，延长节点与网络的寿命
Abstract:
Due to the special character of the wireless sensor network and the energy constraint of the sensor node, the energy- efficient is key question which should solved in the wireless sensor network. Introduces a new strategy of duster- heads election. The remaining energy and the position of the sensor node were taken as the parameter to optimize the process of cluster- head selection. Then it avoids choosing nodes with lower residual energy and had position as duster - heads and then provide the energy load＇s proportionality of sensor node. The simulation results show that the new strategy of cluster - heads election achieves great advance in sensor and network＇ s lifetime
