  • 摘要: 該文旨在為拓撲動態(tài)變化的無線自組織網(wǎng)絡(luò)設(shè)計一種穩(wěn)定性路由機制。首先建模分析了動態(tài)變化網(wǎng)絡(luò)中節(jié)點間通信路徑存在的條件，以及數(shù)據(jù)包在該路徑上可靠傳輸?shù)臈l件，基于以上分析提出了保證路徑有效的關(guān)鍵指標：鏈路持續(xù)時間、擁塞可能性因子。接下來提出基于節(jié)點當前運動情況計算鏈路持續(xù)時間，以及基于緩沖區(qū)隊列長度與隊列長度變化率計算節(jié)點擁塞可能性因子的算法。結(jié)合鏈路持續(xù)時間與節(jié)點擁塞可能性等信息，該文提出了一種面向路徑可靠性及穩(wěn)定性綜合指標的按需路由機制(ODRP-DR)，并利用NS2仿真平臺對該機制性能進行分析，仿真結(jié)果表明，在網(wǎng)絡(luò)拓撲結(jié)構(gòu)動態(tài)變化的情況下能有效減小數(shù)據(jù)包丟包概率，路由重建次數(shù)。
    Abstract: A high stability routing mechanism for the dynamic wireless Ad-hoc network is designed. Firstly, the condition of link existing between the dynamic nodes and the condition that packets can successfully transport across the link are analyzed. Based on the above analysis, two key indicators of link duration and congestion probability factor, which guarantee the effectiveness of the link are proposed. Secondly, the method to calculate the link duration based on the current movement states of those nodes, and the method to calculate the congestion probability factor based on the queue length of the buffer are put forward. Then, combining the link duration and the congestion probability factor, an On-Demand Routing Protocol based on link Duration and Reliability (ODRP-DR) is proposed. Finally, simulations are conducted to evaluate the effectiveness of the routing mechanism in NS2. The results show that the proposed routing mechanism can effectively reduce the probability of packet loss and routing reconstruction.
