摘要
针对传统煤矿无线传感网络因采用固定路由协议、不能根据网络状况改变路由而无法保证突发事故情况下通信可靠性的问题,基于软件定义网络体系及煤矿无线传感网络簇形拓扑结构特点,通过在煤矿无线传感网络簇内增加网关节点,设计了一种矿用软件定义簇形无线传感网络架构。在该网络架构中,每一个域内的网关节点采集传感节点数据并进行域内或域间通信,控制器管理域内的流量、路由和安全,可根据网络状况改变路由,适用于煤矿安全监测领域。
For no guarantee of communication reliability of traditional coal mine wireless sensor network under accident condition because static route protocol cannot change route according to network states,an architecture of software defined cluster wireless sensor network of coal mine was designed by adding gateway nodes in cluster of coal mine wireless sensor network based on software defined network system and characteristic of the cluster topology.In the architecture,the gateway nodes in each domain collect data of sensor nodes for intra-domain or inter-domain communication,and controller manages flow,route and safety of the domain.Wireless sensor network based on the architecture can change route according to network states,which is suitable for coal mine safety monitoring.
