【摘要】：無線傳感網(wǎng)絡(luò)中低功耗自適應(yīng)聚類分簇(LEACH)路由算法等概率選取簇首節(jié)點,容易導(dǎo)致整個網(wǎng)絡(luò)節(jié)點能量損耗出現(xiàn)極端化,減少網(wǎng)絡(luò)生存時間。為此,提出一種針對簇首節(jié)點選取和分簇的改進(jìn)LEACH算法。該算法把整個網(wǎng)絡(luò)區(qū)域分為四個扇形區(qū)域,在每個區(qū)域內(nèi)獨立進(jìn)行分簇路由;然后基站根據(jù)節(jié)點剩余能量和與基站的距離進(jìn)行簇首節(jié)點選擇,節(jié)點根據(jù)簇首節(jié)點和基站接收信號強度選擇路由方式,以均衡網(wǎng)絡(luò)能量消耗。仿真結(jié)果表明,改進(jìn)LEACH算法的網(wǎng)絡(luò)壽命是原有LEACH算法的150%,數(shù)據(jù)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.
