基于协同通信的Ad hoc网络

Ad-hoc Network Based on Cooperative Communication

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 network is widely used in military, disaster relief and other areas. Cooperative communication technology developed in recent years is considered to as important technology for enhancing the performance of wireless communication systems. This paper tells of the application of cooperative technology in Ad hoc network. For the physical layer, an Ad hoc network model based on cooperation is proposed. The topology of Ad hoc network based on cooperation is analyzed, and topology control adopting CC（cooperative communication） is introduced. Theoretical analysis indicates that CC could enhance the robustness of wireless network and improve the communication quality. For the network layer, an idea on the cooperation extension of DSDV routing algorithm is provided.
