【摘要】：為了能有效地利用節(jié)點能量的異構(gòu)性,降低網(wǎng)絡(luò)能耗、延長網(wǎng)絡(luò)穩(wěn)定周期,提出了一種同時考慮節(jié)點剩余能量和節(jié)點至基站距離的多級能量異構(gòu)無線傳感器網(wǎng)絡(luò)的分簇路由算法.在節(jié)點簇間綜合考慮簇頭剩余能量及其與基站的通信能耗,以選擇合適的下一跳路由節(jié)點.仿真結(jié)果表明,該算法可以有效地均衡網(wǎng)絡(luò)能量消耗,延長網(wǎng)絡(luò)穩(wěn)定周期.該路由算法在維持節(jié)點存活個數(shù)、降低網(wǎng)絡(luò)能量消耗及增加網(wǎng)絡(luò)數(shù)據(jù)傳輸吞吐量等指標方面優(yōu)于幾種常見傳感器網(wǎng)絡(luò)路由算法,表明在綜合考慮能量和距離等因素后能夠獲得比單一考慮能量或者距離的算法更優(yōu)的運行結(jié)果.
[Abstract]:In order to effectively utilize the heterogeneity of node energy, reduce network energy consumption and prolong network stability period, A clustering routing algorithm for heterogeneous wireless sensor networks with multi-level energy considering both the residual energy and the distance from the node to the base station is proposed. The residual energy of the cluster head and its communication energy consumption with the base station are considered in order to select the appropriate next-hop routing node. Simulation results show that the proposed algorithm can effectively balance network energy consumption and prolong the network stability period. This routing algorithm is superior to several common sensor network routing algorithms in maintaining the number of nodes surviving, reducing network energy consumption and increasing the throughput of network data transmission. It is shown that when energy and distance are taken into account, better results can be obtained than the single algorithm considering energy or distance.
