【摘要】 本文针对无线网络中的多信道分配问题,提出一种基于跨层设计的多信道分配策略。该策略在MAC层和路由层间进行信道状态信息的交互,MAC层收集各数据信道的状态信息传给路由层,路由层利用该信息在建立路由阶段完成信道分配。该策略实现简便,开销小,通过宏观信道分配实现信道的重利用,降低了信道冲突,避免了信道资源的浪费。更多还原

【Abstract】 Aiming at multi- channel assignment problem in wireless network,a multi- channel assignment strategy based on cross-layer design is proposed in the paper.The strategy exchanges channel status information between MAC layer and route layer.MAC layer collects status information of data channels that is passed to route layer.Route layer completes channel assignment using the status information at the route establishing stage.The strategy can be implemented simply,has little oveifaead,and realizes channel reuse through macro- distribution which reduces channel interference and avoids the waste of channel resources.更多还原
