A Wireless Resource Scheduling Algorithm of Ensuring Maximum Delay of Users in 802.16 System
【摘要】 为了提高802.16系统的用户容量,提出了最少好信道数优先(SGCNF)法则.应用该法则,结合802.16无线调度过程中的二维映射特性,提出了保证用户最大延迟的无线资源调度算法,并对该算法进行了MATLAB仿真类比.仿真结果表明,新算法能够在相同无线信道环境下提高系统的用户容量和无线资源利用率.
【Abstract】 In order to improve the capacity of the 802.16 network,least good channel number first rule was put forward.Based on the rule and 2-D mapping characteristics of wireless scheduling in 802.16 system,a wireless resource scheduling algorithm which can ensure maximum delay was proposed.MATLAB simulation and comparison with other algorithms were made.The simulation result indicates that the capacity and the utilization rate of wireless resource in the same wireless channel condition are improved.
