摘　　要：物联网常遭遇无线电干扰,为此,针对基于正交频分复用的物联网系统(OFDM-IoT),提出基于上校博弈的抗无线电干扰算法。CBG-AJ算法通过IoT控制器保护物联网设备免受恶意无线电干扰。将IoT控制器与干扰攻击者间的抗衡模拟成上校博弈模型。IoT控制器作为防御者,通过在子载波上合理分配功率,对抗干扰攻击,进而降低由干扰攻击引起的误码率。而干扰攻击者通过在子载波上分配干扰功率,降低网络性能。CBG-AJ算法采用进化博弈论方法求解固定策略的纳什均衡。仿真结果表明,提出的CBG-AJ算法能将误码率控制在可接受的范围之内,维护物联网性能。Internet of things often suffers from radio jamming.Therefore,for orthogonal frequency division multiplexing(OFDM)-based internet of things(IoT),colonel blotto game-based anti-radio jamming(CBG-AJ)algorithm is proposed.CBG-AJ algorithm utilizes an IoT controller to protect IoT equipment against the malicious radio jamming.The counterbalance between the IoT controller and the jammer is simulated as a colonel blotto game.The IoT controller,acting as a defender,confronts the jamming attack by allocating its power among the subcarriers reasonably so as to decrease the bit error rates(BER)caused by the jamming attack.And the jamming attacker aims at reducing the system performance by allocating jamming power on the subcarriers.CBG-AJ algorithm utilizes an evolutionary game theory to solve nash equilibrium with fixed-strategy.The simulation results show that the proposed CBG-AJ algorithm can control the BER in an acceptable range and can main the performance of internet of things.
