摘要 提出了一种自适应的满足QoS约束的路由与频谱分配(SA2JR)算法,SA2JR的目标是:在满足无线业务QoS约束的情况下,最大化无线业务接受率,让尽可能多的无线业务需求能够被满足。SA2JR包括2个部分,按需的κ-路径路由(κ-Routing)算法,以及QoS驱动的频谱分配(QDSA)算法。κ-Routing负责为每一个需求产生κ条潜在路由路径,QDSA算法自适应地进行频谱分配,目标是从κ-Routing产生的κ条潜在路由路径中找出一条满足QoS约束的可行路由路径。仿真结果表明SA2JR能达到预定目标,获得了较高的无线业务接受率。 A self-adaptive joint routing（SA2JR） and spectrum allocation algorithm with QoS constraints in cognitive wireless mesh networks was proposed.Maximizing the accept ratio of wireless service was the objective of SA2JR under the QoS constraints.The SA2JR algorithm contained κ-Routing and QDSA algorithm.The κ-Routing algorithm pro-duces κ paths for each wireless service.QDSA algorithm took charge of maintaining a feasible path from the κ paths which produced by κ-Routing algorithm.Simulation results show that SA2JR algorithm can achieve expectation goal.It can achieve a higher accept ratio.
