| 摘 要： | 基于图染色理论提出了2种无线网络中的无线资源共享算法C_TDRS和S_TDGRS.这2种算法分别从子信道和业务流角度考虑,以尽力满足业务需求为目标,兼顾了业务类型和资源共享的公平性.仿真结果表明,2种算法的共享结果在系统吞吐率和比例公平方面比现有算法更接近最优值,并且S_TDGRS算法对2个指标有很好的折衷.

| Abstract: | Two radio resource sharing algorithms for wireless networks,C_TDRS and S_TDGRS,were proposed based on graph coloring.They aimed to satisfy users' demands from the perspective of sub-channel and stream respectively,with traffic type and fairness into consideration.Simulation results show that,the sharing results are closer to the optimal solution than the existing one in terms of system throughput and proportional fairness.Besides,S_TDGRS has a good tradeoff for the two criterions. |

| Keywords: | graph coloring resource sharing algorithms traffic type proportional fairness |
