【摘要】：近年來，Ad-Hoc網(wǎng)絡普遍應用于交通運輸、抗震救災、醫(yī)療保健、環(huán)境監(jiān)測等方面，已逐步滲入到人們的日常生活中。因此人們需要更高的Ad-Hoc網(wǎng)絡通信量，單信道Ad-Hoc網(wǎng)絡由于受限于系統(tǒng)吞吐量和網(wǎng)絡帶寬，已很難滿足較大通信吞吐量的要求。然而，由于多信道網(wǎng)絡環(huán)境允許相鄰節(jié)點在多條路徑上同步通信，且能夠避免信道沖突，所以多信道無線自組織網(wǎng)絡能夠顯著提高網(wǎng)絡吞吐量。因此，對適合多信道Ad-Hoc網(wǎng)絡環(huán)境路由協(xié)議的研究是至關重要的，也是提高網(wǎng)絡容量的關鍵因素，這對促進無線自組織網(wǎng)絡的廣泛應用具有重大的現(xiàn)實意義。 本文在基于Ad-Hoc網(wǎng)絡典型單信道路由協(xié)議NS-2仿真比較的基礎上，搭建多信道多接口路由協(xié)議仿真平臺，并對典型多信道路由策略方案進行仿真分析，充分利用鏈路資源、網(wǎng)絡資源、用戶資源構(gòu)建Ad-Hoc網(wǎng)絡多信道路由策略，在此基礎上提出了適合多信道多接口無線Ad-Hoc網(wǎng)絡環(huán)境的綜合路徑度量策略SPM和SM-AOMDV協(xié)議，并在多信道多接口仿真平臺上對其分別進行不同場景的仿真分析，達到適應網(wǎng)絡環(huán)境、提高網(wǎng)絡容量、優(yōu)化端到端路由性能的目標。 首先，對Ad-Hoc網(wǎng)絡及其路由協(xié)議進行全面的認識，分析介紹NS-2網(wǎng)絡仿真流程及用于評價AODV、DSDV、DSR路由協(xié)議性能的評價指標，然后對這三種典型單信道Ad-Hoc網(wǎng)絡路由協(xié)議仿真比較，分析出適合Ad-Hoc網(wǎng)絡的路由協(xié)議，構(gòu)建路由優(yōu)化目標。 其次，構(gòu)建Ad-Hoc網(wǎng)絡多信道多接口仿真平臺，并在該仿真平臺上，對典型多信道路由策略M-AOMDV進行仿真分析。同時分析比較現(xiàn)有的多信道多接口解決方案，著重介紹適合無線Ad-Hoc網(wǎng)絡的MIMCS方案，為適合Ad-Hoc網(wǎng)絡多信道多接口路由協(xié)議的設計奠定了基礎。 最后，本文提出了適合多信道多接口無線Ad-Hoc網(wǎng)絡環(huán)境的綜合路徑度量策略SPM，，將其結(jié)合MIMCS方案一同應用到AOMDV協(xié)議中便形成了適合多信道多接口無線Ad-Hoc網(wǎng)絡環(huán)境的SM-AOMDV協(xié)議。該策略在AOMDV協(xié)議中綜合考慮了跳數(shù)、鏈路干擾、同一路徑不同鏈路間的信道干擾CIC以及信道切換代價CSC四個因素，通過將SM-AOMDV協(xié)議與典型多信道路由協(xié)議M-AOMDV仿真對比，證明了SM-AOMDV協(xié)議和SPM策略的優(yōu)越性。
[Abstract]:In recent years, Ad-Hoc networks have been widely used in transportation, earthquake relief, medical care, environmental monitoring and other aspects, which have gradually penetrated into people's daily life. Therefore, people need higher traffic in Ad-Hoc networks. Because of the limitation of system throughput and network bandwidth, single-channel Ad-Hoc networks are difficult to meet the requirements of larger communication throughput. However multi-channel wireless ad hoc networks can significantly improve network throughput because adjacent nodes are allowed to communicate synchronously over multiple paths and channel conflicts can be avoided in a multi-channel network environment. Therefore, the research of routing protocols suitable for multi-channel Ad-Hoc network environment is very important and the key factor to improve the network capacity. It is of great practical significance to promote the wide application of wireless ad hoc networks. Based on the simulation and comparison of typical single channel routing protocol (NS-2) in Ad-Hoc network, the simulation platform of multi-channel and multi-interface routing protocol is built in this paper, and the typical multi-channel routing strategy scheme is simulated and analyzed to make full use of link resources. Network resources and user resources are used to construct multi-channel routing strategy for Ad-Hoc network. Based on this, a comprehensive path measurement strategy, SPM and SM-AOMDV protocol, is proposed for multi-channel and multi-interface wireless Ad-Hoc network environment. In order to adapt to the network environment, improve the network capacity and optimize the end-to-end routing performance, the simulation analysis of different scenarios is carried out on the multi-channel and multi-interface simulation platform. First of all, the paper makes a comprehensive understanding of Ad-Hoc network and its routing protocols, analyzes and introduces the simulation flow of NS-2 network and the evaluation indexes used to evaluate the performance of NS-2 network routing protocols, and then compares these three typical single-channel Ad-Hoc routing protocols by simulation. The routing protocol suitable for Ad-Hoc network is analyzed and the route optimization target is constructed. Secondly, the multi-channel and multi-interface simulation platform of Ad-Hoc network is constructed, and the typical multi-channel routing policy M-AOMDV is simulated and analyzed on the platform. At the same time, the existing multi-channel and multi-interface solutions are analyzed and compared, and the MIMCS scheme suitable for wireless Ad-Hoc network is introduced emphatically, which lays a foundation for the design of multi-channel and multi-interface routing protocol suitable for Ad-Hoc network. Finally, this paper proposes a comprehensive path measurement strategy for multi-channel and multi-interface wireless Ad-Hoc network environment, which is combined with MIMCS scheme to form a SM-AOMDV protocol suitable for multi-channel and multi-interface wireless Ad-Hoc network environment. The strategy takes into account four factors in AOMDV protocol, such as hop number, link interference, channel interference CIC between different links of the same path, and channel switching cost CSC. By comparing SM-AOMDV protocol with M-AOMDV, a typical multi-channel routing protocol is simulated and compared. The superiority of SM-AOMDV protocol and SPM strategy is proved.
