摘要
提出一种针对移动自组网共享信道环境自适应跳频处理的实现方法。该方法依据物理层频谱感知动态更新各物理信道频率集,并通过自适应频点分配协议设计,完成结合物理信道划分自适应跳频处理。同时该方法采用信道忙闲程度统计策略,保证网络中每个成员节点以最优信道完成信号发射,降低网络节点间频率碰撞概率,提高全网共享信道利用率和网络可靠性。
In a mobile Ad Hoc network sharing channel environment, an adaptive frequency hopping processing implementation method is introduced, which completes the adaptive frequency hopping processing with a physical channel division based on dynamically updating of the frequency set in each physical channel and the spectrum perception of the physical layer as well as the designing of adaptive frequency allocation protocols. At the same time, the statistical strategy of channel busy degree is used to ensure that each node in the network completes the signal emission with the optimal channel, which can reduce the probability of frequency collision between nodes in the network, and can improve utilization of the sharing channel as well as network reliability of the whole network.
