In this paper, we focus on spectrum sharing in heterogeneous wireless sensor networks (HWSNs) and consider Stackelberg game exploiting the cognitive radio (CR) technology to utilize those scarce resources. In the game, the licensed network controls and prices the available spectrum resource which the WSN relay: actor nodes can purchase and use to serve the(More)
A study on the impact mechanism of safety capacity in petrochemical base is carried out, according to system structure modeling and system dynamics simulation. The hierarchical structure model of 14 factors that affect the safety capacity in petrochemical base is built up. Safety management and emergency management are included in the first hierarchy.
