Colliery Tunnel is a longitudinal limited space with curves and branches. When the tunnel environment changes, the communication channel model is also altering. We can increase the network performance through the cognition of the communication context and application's requirements. In this paper, we designed a cognitive network model for colliery tunnel based on current network facilities and communication...
First, we proposed a heterogeneous information integration framework for colliery based on ontology and SOA. Then, we discussed the three levels of colliery information integration, i.e. datasets' creation, the transparent access of datasets, services' creation and collaboration. The contents were transmitted to specified application through data translation, service process description and data routing...
The present wireless communication system under coal mines is characterized by single pattern, fixed communication frequency, incapability of adaptive to various tunnel environments. To solve the above problems, cognitive radio (CR) is applied to the system. This paper focuses on the application of energy detection algorithms used in the spectrum sensing of various tunnels under mines. The detection...
