摘　　要：为了进一步适应Ad hoc无线网络环境下各种应用的需要,提高网络性能,Ad hoc无线网络的跨层设计已成为目前国内外网络研究的热点和难点问题之一。给出了Ad hoc无线网络跨层设计的定义,分析了跨层设计的原因、优势和主要技术;对跨层设计的方法进行了分类,主要包括四种方法:层间传递相关信息,联合优化网络相关层,融合相邻层,分层作为网络最优化分解,并对它们进行了分析比较和评价;最后探讨了Ad hoc无线网络跨层设计面临的挑战和今后的研究方向。In order to accelerate the development of various applications and high-performances in Ad hoe wireless networks, cross layer design has been discussed and is becoming an important and difficult research problem for Ad hoc wireless network. First cross layer design is defined, the motivations and the advantages of cross layer design are analyzed in the paper. Secondly, all important approaches of cross layer design are depicted and discussed according to different categories： passing information across layers.joint design cooperated layers, merging adjacent layers and layering as optimization decomposition. At the same time the paper evaluates and compares them with performance and complexity. At last the challenges of cross laver design are discussed and the future research work is orooosed.
