Ad hoc网络在军事、救灾等许多领域有广泛的实用价值。协同通信是近几年发展起来的,被认为是增强无线通信系统性能的一项重要技术。讨论了协同技术在Ad hoc网络中的应用。在物理层上,研究了基于协同的Adhoc网络的网络模型,分析了基于协同的Ad hoc网络拓扑结构,引入采用协同通信的拓扑控制,通过理论分析证实通过协同可增强无线网络的健壮性。在网络层上,给出了基于DSDV协同路由算法的扩展思路。
Ad hoc networks in the military, disaster relief and other fields have a wide range of practical value. Cooperative communication has developed in recent years and is considered as an important technology to enhance the performance of wireless communication systems. The application of collaborative technology in Ad hoc networks is discussed. At the physical layer, we study the network model of collaborative Adhoc network, analyze the topological structure of Ad hoc network based on collaboration, and introduce topological control using cooperative communication. Theoretical analysis proves that robustness of wireless network can be enhanced through coordination. At the network layer, an extended idea based on DSDV collaborative routing algorithm is given.
