【摘要】：近年來(lái)，Ad-Hoc網(wǎng)絡(luò)普遍應(yīng)用于交通運(yùn)輸、抗震救災(zāi)、醫(yī)療保健、環(huán)境監(jiān)測(cè)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(luò)通信量，單信道Ad-Hoc網(wǎng)絡(luò)由于受限于系統(tǒng)吞吐量和網(wǎng)絡(luò)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(luò)環(huán)境允許相鄰節(jié)點(diǎn)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(wú)線自組織網(wǎng)絡(luò)能夠顯著提高網(wǎng)絡(luò)吞吐量。因此，對(duì)適合多信道Ad-Hoc網(wǎng)絡(luò)環(huán)境路由協(xié)議的研究是至關(guān)重要的，也是提高網(wǎng)絡(luò)容量的關(guān)鍵因素，這對(duì)促進(jìn)無(wú)線自組織網(wǎng)絡(luò)的廣泛應(yīng)用具有重大的現(xiàn)實(shí)意義。 本文在基于Ad-Hoc網(wǎng)絡(luò)典型單信道路由協(xié)議NS-2仿真比較的基礎(chǔ)上，搭建多信道多接口路由協(xié)議仿真平臺(tái)，并對(duì)典型多信道路由策略方案進(jìn)行仿真分析，充分利用鏈路資源、網(wǎng)絡(luò)資源、用戶資源構(gòu)建Ad-Hoc網(wǎng)絡(luò)多信道路由策略，在此基礎(chǔ)上提出了適合多信道多接口無(wú)線Ad-Hoc網(wǎng)絡(luò)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(tái)上對(duì)其分別進(jìn)行不同場(chǎng)景的仿真分析，達(dá)到適應(yīng)網(wǎng)絡(luò)環(huán)境、提高網(wǎng)絡(luò)容量、優(yōu)化端到端路由性能的目標(biāo)。 首先，對(duì)Ad-Hoc網(wǎng)絡(luò)及其路由協(xié)議進(jìn)行全面的認(rèn)識(shí)，分析介紹NS-2網(wǎng)絡(luò)仿真流程及用于評(píng)價(jià)AODV、DSDV、DSR路由協(xié)議性能的評(píng)價(jià)指標(biāo)，然后對(duì)這三種典型單信道Ad-Hoc網(wǎng)絡(luò)路由協(xié)議仿真比較，分析出適合Ad-Hoc網(wǎng)絡(luò)的路由協(xié)議，構(gòu)建路由優(yōu)化目標(biāo)。 其次，構(gòu)建Ad-Hoc網(wǎng)絡(luò)多信道多接口仿真平臺(tái)，并在該仿真平臺(tái)上，對(duì)典型多信道路由策略M-AOMDV進(jìn)行仿真分析。同時(shí)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(wú)線Ad-Hoc網(wǎng)絡(luò)的MIMCS方案，為適合Ad-Hoc網(wǎng)絡(luò)多信道多接口路由協(xié)議的設(shè)計(jì)奠定了基礎(chǔ)。 最后，本文提出了適合多信道多接口無(wú)線Ad-Hoc網(wǎng)絡(luò)環(huán)境的綜合路徑度量策略SPM，，將其結(jié)合MIMCS方案一同應(yīng)用到AOMDV協(xié)議中便形成了適合多信道多接口無(wú)線Ad-Hoc網(wǎng)絡(luò)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(jià)CSC四個(gè)因素，通過(guò)將SM-AOMDV協(xié)議與典型多信道路由協(xié)議M-AOMDV仿真對(duì)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.
