无线Mesh网络是由移动节点自组形成的多跳网络架构,非常适合煤矿地面工作区的无线覆盖,但在Mesh中的新移动节点接入网络时,需要对节点的身份进行认证,目前尚未有可靠的安全认证方案。在对无线Mesh的认证机制802.1x进行分析的基础上提出该机制的缺陷,并提供了一种新的基于PANA认证的解决方案。使用安全、可靠的无线网络进行煤矿井下监控和调度,对于改善煤矿的安全生产管理有着重要的现实意义。
Wireless Mesh Network is a multi-hop network architecture formed by mobile nodes. It is very suitable for wireless coverage of coal mine ground work area. However, when a new mobile node in Mesh accesses the network, it needs to authenticate the identity of the node. At present, Reliable safety certification program. Based on the analysis of the 802.1x authentication mechanism of Wireless Mesh, this paper proposes the defect of this mechanism and provides a new solution based on PANA authentication. The use of safe and reliable wireless network for coal mine monitoring and dispatching has important practical significance for improving the safe production management in coal mines.
