提出了一种用于Mesh拓扑结构无线传感器网络的自适应跳频算法,网络中的节点根据邻居的连接信息选择自己与邻居通信的备用信道,一旦当前信道质量变差,通信双方放弃当前信道,使用备用信道进行通信,从而提高了网络的可靠性.算法有效地利用了多信道进行通信,在网络密度不太大且网络拓扑变化不频繁的情况下是有效的. An adaptive frequency hopping algorithm for Mesh topology wireless sensor networks is proposed. Nodes in the network choose their own spare channels to communicate with their neighbors according to the neighbor’s connection information. Once the current channel quality deteriorates, both the communication parties abandon the current channel, The use of alternate channel for communication, thereby enhancing the reliability of the network.The algorithm effectively use multi-channel communication, network density is not too large and the network topology changes infrequently is effective.
