【摘要】：无线传感网络中低功耗自适应聚类分簇(LEACH)路由算法等概率选取簇首节点,容易导致整个网络节点能量损耗出现极端化,减少网络生存时间。为此,提出一种针对簇首节点选取和分簇的改进LEACH算法。该算法把整个网络区域分为四个扇形区域,在每个区域内独立进行分簇路由;然后基站根据节点剩余能量和与基站的距离进行簇首节点选择,节点根据簇首节点和基站接收信号强度选择路由方式,以均衡网络能量消耗。仿真结果表明,改进LEACH算法的网络寿命是原有LEACH算法的150%,数据吞吐量提升了3倍。
[Abstract]:In wireless sensor networks, low power adaptive clustering (Leach) routing algorithm can select cluster head nodes, which will lead to the energy loss of the whole network and reduce the lifetime of the network. Therefore, an improved Leach algorithm for cluster head node selection and clustering is proposed. The algorithm divides the whole network area into four sectorial regions and performs cluster routing independently in each region. Then the base station selects the cluster head node according to the residual energy of the node and the distance from the base station. In order to equalize network energy consumption, nodes select routing methods according to the received signal strength of cluster head node and base station. The simulation results show that the network lifetime of the improved Leach algorithm is 150 times that of the original Leach algorithm, and the data throughput is increased three times.
