【摘要】：近年來無線傳感器網(wǎng)絡(luò)(Wireless Sensor Network, WSN)發(fā)展迅速,其具有結(jié)構(gòu)靈活、部署方便、自組織等特點(diǎn),適用于煤礦井下等惡劣環(huán)境。無線傳感器網(wǎng)絡(luò)中節(jié)點(diǎn)數(shù)目龐大且電池充電及更換非常不便,因此節(jié)點(diǎn)能耗問題是網(wǎng)絡(luò)重點(diǎn)解決的問題之一。路由協(xié)議是無線傳感器網(wǎng)絡(luò)技術(shù)研究的核心技術(shù)之一。設(shè)計(jì)有效的路由協(xié)議,充分利用節(jié)點(diǎn)能量、均衡節(jié)點(diǎn)能耗,從而延長WSN的生命周期是非常必要的。本文首先對無線傳感器網(wǎng)絡(luò)及路由協(xié)議進(jìn)行分析,綜合煤礦井下無線傳感器網(wǎng)絡(luò)特點(diǎn),分析了井下無線傳感器網(wǎng)絡(luò)路由協(xié)議的設(shè)計(jì)目標(biāo)及選擇分簇路由協(xié)議的優(yōu)勢。但分簇路由雖然節(jié)省了通信能量,卻存在能耗不均等問題,負(fù)責(zé)簇內(nèi)管理及通信的簇首及需要轉(zhuǎn)發(fā)數(shù)據(jù)而負(fù)擔(dān)過重的匯聚節(jié)點(diǎn)附近的節(jié)點(diǎn)能量消耗過快,直接造成節(jié)點(diǎn)死亡率的升高、網(wǎng)絡(luò)壽命的縮減�；诿嫦蜃灾蔚挠�(jì)算(Autonomy-Oriented Computing,AOC)提出一種閾值響應(yīng)的煤礦井下Agent分簇路由協(xié)議TRMAC.該協(xié)議中WSN網(wǎng)絡(luò)被轉(zhuǎn)化為AOC系統(tǒng),網(wǎng)絡(luò)中傳感器節(jié)點(diǎn)由一些自治的Agent(智能體)管理,所有行為和操作均自治,每個(gè)個(gè)體達(dá)到自身目標(biāo)后,系統(tǒng)隨之達(dá)到目標(biāo)。協(xié)議通過設(shè)定能量閾值來均衡能耗,避免節(jié)點(diǎn)因能耗過大而過早失效。從而延長網(wǎng)絡(luò)生命周期。最后對TRMAC算法進(jìn)行仿真,并與經(jīng)典路由協(xié)議LEACH算法進(jìn)行比較分析。
[Abstract]:In recent years, wireless sensor network (WSN) wireless Sensor Network, WSN) has developed rapidly. It has the characteristics of flexible structure, convenient deployment, self-organization and so on. It is suitable for coal mine and other harsh environment. The number of nodes in wireless sensor networks is huge and the battery charging and replacement is very inconvenient, so the problem of node energy consumption is one of the most important problems to be solved in wireless sensor networks. Routing protocol is one of the core technologies of wireless sensor networks. It is necessary to design an effective routing protocol to make full use of node energy and to balance node energy consumption so as to prolong the life cycle of WSN. Firstly, this paper analyzes the wireless sensor network and its routing protocol, synthesizes the characteristics of underground coal mine wireless sensor network, analyzes the design goal of the underground wireless sensor network routing protocol and the advantages of selecting cluster routing protocol. However, although cluster routing saves communication energy, it has the problem of unequal energy consumption. The cluster head, which is responsible for the management and communication within the cluster, and the nodes near the convergence node, which need to transmit data and need to forward data, consume too much energy. It directly causes the increase of node mortality and the reduction of network life. Based on Autonomy-Oriented Computing (AOC), a Agent clustering routing protocol for underground coal mine is proposed. In this protocol, the WSN network is transformed into a AOC system. The sensor nodes in the network are managed by some autonomous agents. All behaviors and operations are autonomous. After each individual reaches its goal, the system achieves the goal. The protocol equalizes energy consumption by setting energy threshold to avoid node failure due to excessive energy consumption. Thus prolongs the network life cycle. Finally, the TRMAC algorithm is simulated and compared with the classical routing protocol LEACH algorithm.
