摘要:

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. 

Abstract:

An adaptive channel hopping algorithm that can be used in wireless mesh sensor networks is designed. The nodes themselves select proper channels independently and use them to communicate with its neighbors automatically. Once a pair of nodes find their current channel had been deteriorated, they abandoned the current channel and choose reserved channels at once, so the reliability of the network is improved. The algorithm makes use of multichannels efficiently. It is concluded that the algorithm is practicable in the network with moderate density and the topology is relatively static. 
