摘要
在LEACH协议中,由于汇聚节点基站与簇首节点是单跳性传送数据,并且簇首节点的轮换具有随机性,使得能量消耗增加,出现了网络生命周期延长的问题,于是提出了基于LEACH能量高效的多跳多路径路由协议EMHMP。相比于原始的LEACH路由协议,本文提出的EMHMP算法中能量高的节点被选为簇首;节点的剩余能量、最小跳数和数据包大小决定了EMHMP算法中继节点的选取和最佳传输路径的选取。在备用路由表中选择数据传输路径;进而使得网络生命周期最大化。能量阈值的设计规则为剩余能量高的节点在簇首轮换时不需要进行轮换。Matlab仿真实验表明,与LEACH协议相比基站接受的数据总量提升了4.9倍,生命周期延长了约55%。
In the LEACH protocol,since the aggregation node base station and the cluster head node are single-hop transmission data;and the rotation of the cluster head node is random;the energy consumption is increased;the problem of the network life cycle is slowed down;and the energy efficiency based on LEACH is proposed.The multi-hop multipath routing algorithm EMHMP is compared to the original LEACH routing protocol.First,the node with high energy is selected as the cluster head;the selection of the relay node of the EMHMP algorithm and the selection of the optimal transmission path are determined by the remaining energy of the node,the minimum hop count and the packet size.The network life cycle is maximized by the selection of the data transmission path in the alternate routing table.The design rule of the energy life threshold is that the node simulation point with high residual energy does not need to perform the cluster head rotation when the cluster head rotation occurs.MATLAB simulation experiments show that compared with the LEACH protocol,the total amount of data received by the base station is increased by 4.9 times and the life cycle is extended by about 55%.
