摘　　要：ad hoc网络与传统有线和无线蜂窝网络有着显著的区别,基于传统的分层协议栈的设计方法不再适合adhoc网络,而应采用一种新型的跨层协议栈和跨层设计方法。本文首先阐述了adhoc网络的特点和传统的分层协议栈的弊端,介绍了跨层设计的概念。然后,详细分析了adhoc网络中跨层设计的方法,包括策略、体系结构和信令交互方式,探讨了跨层设计的相关技术和面临的挑战。最后,总结了全文并指出了今后的工作方向。There are distinct difference between ad hoc network and traditional wired and cellular networks. Traditional layered protocol stack based design methods are not suitable for ad hoc network, so a novel cross-layer protocol stack and design methods should be introduced. In this paper characteristics of ad hoc network and disadvantages of traditional layered protocol stack are explained and the concept of cross-layer design are introduced firstly. Then, cross-layer design methods in ad hoc network are analyzed in detail, including design policies, architecture and signal interaction. Afterwards, related technologies and challenges of cross-layer design are discussed. Finally, a summarization of the paper is given and future work direction is pointed out.
