【摘要】：近年来无线传感器网络(Wireless Sensor Network, WSN)发展迅速,其具有结构灵活、部署方便、自组织等特点,适用于煤矿井下等恶劣环境。无线传感器网络中节点数目庞大且电池充电及更换非常不便,因此节点能耗问题是网络重点解决的问题之一。路由协议是无线传感器网络技术研究的核心技术之一。设计有效的路由协议,充分利用节点能量、均衡节点能耗,从而延长WSN的生命周期是非常必要的。本文首先对无线传感器网络及路由协议进行分析,综合煤矿井下无线传感器网络特点,分析了井下无线传感器网络路由协议的设计目标及选择分簇路由协议的优势。但分簇路由虽然节省了通信能量,却存在能耗不均等问题,负责簇内管理及通信的簇首及需要转发数据而负担过重的汇聚节点附近的节点能量消耗过快,直接造成节点死亡率的升高、网络寿命的缩减。基于面向自治的计算(Autonomy-Oriented Computing,AOC)提出一种阈值响应的煤矿井下Agent分簇路由协议TRMAC.该协议中WSN网络被转化为AOC系统,网络中传感器节点由一些自治的Agent(智能体)管理,所有行为和操作均自治,每个个体达到自身目标后,系统随之达到目标。协议通过设定能量阈值来均衡能耗,避免节点因能耗过大而过早失效。从而延长网络生命周期。最后对TRMAC算法进行仿真,并与经典路由协议LEACH算法进行比较分析。
[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.
