【摘要】：針對(duì)GAF算法的不足,提出一種基于相交圓結(jié)構(gòu)的改進(jìn)GAF算法。采用相交圓結(jié)構(gòu)模型進(jìn)行單元格劃分,增大每個(gè)單元格的面積及節(jié)點(diǎn)單跳覆蓋范圍,在相交圓的重疊區(qū)域中進(jìn)行中轉(zhuǎn)節(jié)點(diǎn)的選擇,實(shí)現(xiàn)簇頭間的多跳路由;在簇頭選擇階段,根據(jù)節(jié)點(diǎn)吞吐率等條件定義的簇頭選擇函數(shù)來選擇簇頭。仿真結(jié)果表明,改進(jìn)GAF算法能有效節(jié)約能耗,延長網(wǎng)絡(luò)生存期。
[Abstract]:An improved GAF algorithm based on intersecting circular structure is proposed to solve the shortcoming of GAF algorithm. The intersecting circular structure model is used to divide the cells to increase the area of each cell and the coverage range of single hop node. In the overlapping region of intersecting circle, the transfer nodes are selected to realize the multi-hop routing between cluster heads, and the cluster heads are selected according to the cluster head selection function defined according to the node throughput and other conditions in the cluster head selection stage. The simulation results show that, The improved GAF algorithm can effectively save energy and prolong the network lifetime.
