混合业务公平的宽带电力线正交频分复用系统跨层资源分配
Cross-layer Resource Allocation Based on Mixed-service Fairness for Broadband Power-line OFDM System
摘要
Abstract
Under the case of insufficient resources, this paper aimed at the multi-objective optimization of cross-layer resource allocation for broadband power line communication (BPLC) system based on orthogonal frequency division multiplexing (OFDM). Firstly it considered the allocation requirements of mixed-service, such as the fixed rate/bits for real-time (RT) service and the minimum rate/bits for non-real-time (NRT) service. Secondly, it also considered the constraint of fixed total power and equal subcarrier-power in the resource allocation. And then a multi-objective optimization model of cross-layer resource allocation was made to satisfy the mixed-service quality of service (QoS) requirements. These requirements were represented by the stability metric of RT service and the fairness metric of NRT service. On the model above, finally this paper proposed a related cross-layer resource allocation algorithm based on mixed-service fairness, which combined with inter-service bit-rate adaption. In typical environment of PLC communication channel, simulations illustrate that the proposed algorithm shows better performances for the requirements of BPLC mixed-service and multi-objective optimization. These performances may be depicted in both Mac-layer QoS metrics such as delay and Physics-layer QoS metric such as the fairness and the stability of service.关键词
