The coal seam being mined by #3103 working face of Shangzhuang Coal Mine is relatively close to its adjacent seam. Moreover, the adjacent seam contains considerably high gas content. Therefore, in order to prevent excessive gas exceeding the stipulated limit as a result of massive gas emission from the adjacent seam during the initial collapse of the roof, forced caving scheme is worked out to deal...
For optimizing the performance of cooperative communication system, it presents a multi-relay amplify forwarding (AF) and decoded forwarding (DF) cooperation node selection algorithm based on the residual energy, considering jointly the residual energy information of nodes and channel state information(CSI) to optimize network lifetime, using the weighting function to select the relay set. Simulation...
In order to optimize the performance of cooperative communication system, it presents a dynamic multi-relay amplify forwarding (AF) cooperation node selection algorithm, considering jointly the residual energy information of nodes and channel state information(CSI) to optimize network lifetime. Theoretical analysis and simulation results show that, for dynamic relay power distribution, performance...
