摘　　要：无线Ad Hoc网络具有自组织、自修复、自管理等能力,能够适应动态变化的网络环境,在军事及应急救灾通信上已经得到广泛应用。多样化应用场景对无线Ad Hoc网络带来了诸如更大的网络规模、更高的信息吞吐量等要求,而采用多接口、多信道设计是满足以上需求的重要途径之一。此外,无线信道资源相对紧张,必须在解决多个节点公平接入共享信道的基础上,尽量提高信道使用效率。因此,设计了一种基于TDMA的多接口多信道网络信道资源分配方法,采用面向节点与面向链路混合的分配机制,有效提高了多接口多信道无线Ad Hoc网络的资源利用效率。Wireless Ad Hoc networks,characterized by self-organizing,self-repairing and self-managing,which can adapt to the dynamically changing network environment,is widely used in military and emergency disaster communications.The applications in diversified scenes impose requirements on wireless Ad Hoc networks,such as greater network size and higher information throughput,etc.,and the adoption of multiple interfaces and multiple channels design is one of the important ways to meet the above requirements.In addition,the wireless channel resources are relatively tight,and the channel usage efficiency must be improved as much as possible on the basis of solving fair access of multiple nodes to the shared channel.Therefore,a multi-interface multi-channel channel resource allocation method based on TDMA is designed,which adopts a hybrid mechanism of node-oriented and link-oriented allocation,and effectively improves the resource utilization efficiency of multi-interface multi-channel wireless Ad Hoc networks.
