摘要
基于M2M终端组的资源分配策略可以有效提高M2M通信中的资源利用率。本文研究了M2M通信系统中基于组的保证不同组间传输速率的比例公平资源分配问题,提出了一种次优的能够保证不同终端组间传输速率比例公平的资源分配算法,并通过仿真对算法的性能进行了验证,给出了速率最大化算法与终端组比例公平算法的性能比较。
Group based resource allocation schemes can improve the efficiency of resource utilization for M2M communication.In this paper,group based resource allocation schemes are studied to guarantee the proportional fairness of data rate among different terminal groups in OFDMA systems.A sub-optimal algorithm is designed to achieve proportional fairness.At last,Monte Carlo simulations are done to show the performance of proposed algorithm.
