摘　　要：介绍了一种基于多信道的通信方法,多信道技术允许多对节点在一个干扰范围内同时通信,是提高网络路径容量的有效手段。以多信道通信网络为研究对象,讨论了多信道条件下的网络容量估算问题。分析表明,通过设置独立控制信道交换节点和信道信息对可用信道进行分配,可以很好地解决多信道Ad Hoc网络通信中的隐藏节点和暴露节点问题,适合于用来构建大型通信网络。A communication method based on multi-channel is exhibited in this paper,multi-channel technology is an approach that can effectively boost the path capacity of communication networks due to permitting mukiple pairs of nodes to simultaneously communicate in an interference range. The paper takes communication network based on multi-channel as the study object,the Network capacity estimation problem is discussed in multi-channel condition.The analysis indicated that multi-channel assignment can resolve the hidden and exposed node problems well at the same time by employing dedicated control channel, exchanging infor- mation of nodes and channels,it is also suitable to constitute large Ad Hoc network.
