摘　　要：无线资源调度技术是无线网络对用户提供服务质量保障的关键。层次分析的跨异构子网联合无线资源调度算法以编队通信需求为基础,综合考虑了跨异构子网端到端传输性能最优化问题,通过层次分析法建立了跨异构子网联合资源调度模型。在此模型基础上,求解了各方案的灰度关联系数,得出了跨异构子网无线资源调度优化算法(AHP-WRA)。对AHP-WRA算法、随机接入(RA)算法和高带宽优先(HBA)算法进行了对比仿真,仿真结果表明,在系统有效吞吐量方面AHP-WRA算法明显优于其他两种算法。Wireless resource allocation algorithm is a key technology to the cooperative wireless resource manage- ment. A good resource allocation algorithm can prevent the network congestion effectively, guarantee the quality of service. In this paper, formation of heterogeneous topology of overlapping subnets is studied, the different service types of ship is considered. Based on several factors and analytic hierarchy process, cooperative wireless resource allocation is modeled, on this basis, gray-scale association analysis is used to calculate the relating coefficient. The plan which has the largest relating coefficient is considered to the optimal allocation scheme, so as to optimize the system transmission performance. Computer simulations show that the transmission performance is improved signif- icantly as opposed to conventional allocation algorithm.
