Power control mechanism in software defined wireless networking

The explosive growth of the wireless network data brings a lot of pressure to the limited network resources, the network energy saving problem is increasingly outstanding. Software defined wireless networking separates wireless network control plane from the packet forwarding plane, and makes the network more flexible, thus software defined wireless networking has been widely used. Aiming at software defined wireless networking energy saving problem, this paper proposed a power control mechanism which is based on software defined wireless networking, on the basis of this mechanism a power allocation strategy is proposed based on game theory, the strategy controls node's transmission power under the requirements of node's transmission signal-to-noise ratio. Simulation results show that the proposed mechanism can ensure reliable transmission network at the same time to achieve the purpose of energy conservation through the rational allocation transmission power of nodes.
