Topology design and resource allocation of emergency rescue communication networks for underground mines
摘要
Abstract
To study the problems of existing underground mine emergency rescue communications networks,node deployment and resource allocation schemes for underground mine emergency rescue wireless Mesh networks were analyzed from backbone routing layer,gateway,one and terminal access one.In the consideration of network robustness and channel interference,a design of trip topology is proposed for the backbone layer; for the gateway layer,a gateway resource optimal allocation model is proposed so as to avoid gateway bottleneck and resource waste; for the access layer,a backup AP mechanism is put forward to reserve energy and reduce traffic conflicts.Simulation results prove that the gateway optimal allocation model is able to prevent gateway bottleneck and optimize gateway resource utilization.Besides,the deployment design of all layers are rational and capable of improving emergency network properties on capacity,resource utilization and network robustness.关键词
