Utility Function Based Network Access Method in Power Grid HetNets with QoS Guarantee
-
Abstract
With the development of power grid Internet of Things (PIoT), more and more communication access networks are introduced in PIoT system. However, due to the overlapping coverage among heterogeneous networks, the existing QoS guarantee methods can not meet diversified requirements of multiple applications and challenges by network handover in future smart grid. This paper proposed a novel network access method for QoS guarantee by utility function. First, we designed a utility function evaluation model. Secondly, the network mapping algorithm of heterogeneous access networks was proposed. Finally, the performance and reliability of QoS guarantee method of heterogeneous access network were verified by simulations.
