基于LEACH协议的研究与改进

LEACH Agreement-based on Research and Improvement

无线传感器网络中如何节能是一个关键问题。对经典的LEACH协议做研究与改进,并提出了一种新型的动态网络转换机制。该算法通过综合考虑候选节点的地理位置、剩余能量等参数来进行网络协议的选择,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,新型的动态网络协议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。

As wireless sensor nodes limited battery power,energy saving is a key issue in wireless sensor networks.This paper focuses on the research and improvement of the classical LEACH（Low Energy Adaptive Clustering Hierarchy） agreement,and a new type of dynamic network mechanisms.By considering comprehensively the selection of network protocols of node location,residual energy,and other parameters,The method reduces effectively the possibility of low energy and poor positioning being selected the first cluster node,further ensuring balance of network nodes energy load.The simulative results show that the new type of dynamic network protocol mechanisms can effectively balance the energy consumption of nodes,and extend the life span of nodes and networks.
