无线网状网络路由协议在矿山应急通信中的应用研究

无线网状网络(Wireless Mesh Network,WMN)在矿山应急通信系统中的稳定拓扑结构以及高容量高速率的性能给路由协议的设计提出了新的要求，为了得出更适用于矿山应急的WMN路由协议，分类阐述了主动路由协议、按需式路由协议和混合式路由协议三类路由协议，并且从多方面介绍了AODV、AOMDV和HWMP三种常见路由协议的性能并分类综述了常见的改进措施，对于网络利用率问题，借助能量消耗的平衡策略进行改进，对于路由开销大的问题，从优化节点间的移动机制降低节点能耗方面改进，对于链路干扰的问题，从分配节点任务队列和预防网络热点两方面进行改进，结果表明AODV路由协议相较于其他协议更有优越性，最后，从Mesh网络管理和改进链路故障、数据机密性等路由问题展望未来的研究方向。

Advances of wireless Mesh routing protocol in mine emergency communication

The stable topology and high-capacity and high-speed performance of Wireless Mesh Network (WMN) in mine emergency communication system put forward new requirements for the design of routing protocols. In order to get a WMN routing protocol more suitable for mine emergency, three types of routing protocols, active routing protocol, on-demand routing protocol and hybrid routing protocol, were classified and elaborated. Furthermore, the performance of AODV, AOMDV and HWMP were introduced and the common improvement measures were reviewed from various aspects. For the issue of network utilization, the balance strategy of energy consumption was employed to improve the performance. For the issue of high routing overhead, the movement mechanism between nodes were optimized to reduce energy consumption. For the issue of link interference, assignment of node task queues and prevention of network hotspots were used to improve the link interference. The results show that the AODV routing protocol has more advantages than other protocols. At last, the future research directions were prospected from the aspects of Mesh network management and improvement of link failure, data confidentiality and other routing issues.
