摘　　要：针对移动自组织分组无线网络(移动Ad-Hoc网络)在实际应用中容易受到恶意干扰,导致通信性能以及抗干扰性能较低的问题,提出了基于认知频谱的移动Ad-Hoc网络在线抗干扰模型;将移动Ad-Hoc网络集成化处理,计算移动Ad-Hoc网络干扰认知的路由代价,基于认知频谱干扰的能量有效路由方法结合干扰认知路由代价以及距离、能量路由代价的计算结果,建立移动Ad-Hoc网络在线抗干扰模型;在不同大小白噪声干扰情况下对设计模型进行对比测试,测试结果表明,采用该模型在不同大小白噪声干扰情况下均具有较高的网络能效以及吞吐率,不同频带利用率情况下传输时延均低于200 ms,可为提升移动Ad-Hoc网络的生存能力和防护性能提供参考。Aiming at the problem that mobile ad hoc packet radio network is vulnerable to malicious interference in practical application,resulting in low communication performance and anti-interference performance,an online anti-interference model design of mobile ad hoc network based on cognitive spectrum was proposed.The mobile ad hoc network was integrated,and the routing cost of interference cognition was calculated.The energy efficient routing method based on cognitive spectrum interference was combined with the calculation results of interference cognitive routing cost,distance and energy routing cost,and an online anti-interference model of mobile ad hoc network was established.In the case of different white noise interference,the test results show that the model has high network energy efficiency and throughput,and the transmission delay is less than 200 ms under different band utilization,which provides reference for improving the survivability and protection performance of mobile ad hoc network.
