Broadband Power Line Carrier Communication MAC Layer Scheduling Algorithm for Multi-service Transmission Requirements in Electric Internet of Things

Abstract

Since traditional power line carrier communication resource allocation algorithm does not consider the mixed services QoS requirements and the queue buffer the MAC layer, the user could not be reasonably scheduled in mixed service flow, which causes the problem of poor distribution balance among different users. This paper proposes a MAC layer user scheduling algorithm for broadband power line carrier communication in a concurrent mixed service scenario. The algorithm dynamically prioritizes the data packets in the user buffer area according to the QoS requirements of the application layer power multi-service and the queue length in the data link layer buffer area, and gives the minimum physical layer required to meet the QoS requirements of mixed services transmission rate, and then realize the MAC layer user scheduling process of broadband power line carrier communication in the concurrent mixed service scenario.
