Min Lu, Hong Bo Zhu, Yangling Chen, Peng Lin · 2018
To solve the problem of low resource utilization in power wireless access networks and guarantee the QoS of power services effectively, a resource-aware and cross-layer resource allocation mechanism for power wireless access network is proposed. First of all, according to the characteristics of power wireless access network, a virtualized system model based on SDN is proposed. The underlying resources are virtualized and abstracted. The resources state of physical layer and the different QoS of service layer are perceived by SDN controller. Then, considering the factors of cost, network load and QoS constraints, the resource allocation model of power wireless access network is proposed. Finally, the resource-aware dynamic resource allocation algorithm is designed to solve the optimal resource allocation of wireless access network under the condition of satisfying QoS requirements. The simulation results show that the resource-aware and cross-layer resource allocation mechanism proposed in this paper improves network resource utilization and significantly improves network operation efficiency under the premise of meeting QoS requirements of power services.
