【摘要】：針對(duì)未來航空集群網(wǎng)絡(luò)中節(jié)點(diǎn)間通信可靠性保障問題,提出一種基于移動(dòng)預(yù)測的鏈路可靠性估計(jì)路由選擇策略。首先,使用基于地理位置的移動(dòng)預(yù)測方法對(duì)鄰居節(jié)點(diǎn)的位置進(jìn)行準(zhǔn)確預(yù)測。其次,根據(jù)預(yù)測結(jié)果對(duì)當(dāng)前節(jié)點(diǎn)的通信范圍進(jìn)行分區(qū),對(duì)不同鄰居節(jié)點(diǎn)所在區(qū)域的鏈路可靠性分別估計(jì)得到相應(yīng)的可靠性估計(jì)函數(shù)值。根據(jù)得到的可靠性函數(shù)值使用概率選擇模型并結(jié)合跳數(shù)因子進(jìn)行路由選擇。最后,以優(yōu)化鏈路狀態(tài)路由協(xié)議(Optimized Link State Routing protocol,OLSR)為基礎(chǔ)對(duì)路由選擇策略細(xì)節(jié)進(jìn)行描述,并仿真驗(yàn)證了提出的路由選擇策略的有效性。實(shí)驗(yàn)結(jié)果表明,該策略在適用于航空集群網(wǎng)絡(luò)的基礎(chǔ)上,能有效提高網(wǎng)絡(luò)中節(jié)點(diǎn)間通信的可靠性。
[Abstract]:Aiming at the reliability guarantee problem of communication between nodes in future aviation cluster networks, a route selection strategy for link reliability estimation based on mobile prediction is proposed. Firstly, the location of neighbor nodes is accurately predicted by using geographical location based mobile prediction method. Secondly, according to the prediction results, the communication range of the current node is partitioned, and the link reliability of different neighbor nodes is estimated respectively to obtain the corresponding reliability estimation function. The probabilistic selection model is used according to the reliability function value and the hop factor is used to select the route. Finally, based on the optimized Link State routing protocol OLSR, the details of the routing strategy are described, and the effectiveness of the proposed routing strategy is verified by simulation. The experimental results show that the proposed strategy can effectively improve the reliability of communication between nodes on the basis of being suitable for the aviation cluster network.
