摘要: 該文提出了一種新的移動Ad hoc網(wǎng)絡(luò)QoS路由算法：模糊邏輯QoS動態(tài)源路由算法。算法從模糊理論的思想出發(fā)，將業(yè)務(wù)的多個(gè)QoS參數(shù)進(jìn)行綜合評判產(chǎn)生一類以語言變量描述的請求，在修改動態(tài)源路由協(xié)議為多徑路由算法的基礎(chǔ)之上，對比各條路徑綜合模糊路由狀態(tài)，選擇出最適合業(yè)務(wù)請求的路徑。仿真顯示算法在支持QoS的同時(shí)對移動Ad hoc網(wǎng)絡(luò)因拓?fù)鋭討B(tài)變化而引起的信息不精確性有很好的適應(yīng)度。

Abstract: A new QoS routing algorithm for mobile Ad hoc networks, Fuzzy Logic QoS Dynamic Source Routing (FLQDSR), is proposed in this paper. The idea of FLQDSR starts from the fuzzy theory. It integrates the multiple QoS parameters of traffic into one request that is represented by Language variable through integrated fuzzy judgment. Based on the multiple paths routing algorithm which is modified the Dynamic Source Routing (DSR), FLQDSR compares the integrated QoS fuzzy value of each path and selects the most appropriate one according to the fuzzy rules. Simulation results show that FLQDSR can tolerate the imprecise information which is caused by the dynamic network topology well while supporting QoS function. -
