摘　　要：信息技术的不断发展使泛在式异构一体化综合网络应运而生,包含了节点异构性、链路异构性和网络协议异构性等特点的异构无线传感器网络(HWSN)已在众多领域得到大量应用.为进一步提高HWSN网络整体性能,对HWSN进行跨层设计已成为当前研究的一个重要途径.但目前关于HWSN跨层协议的研究仍处于起步阶段,且实际应用于HWSN的跨层协议尚不成熟.通过分析HWSN跨层设计的目的和方法,从应用层、传输层、网络层、MAC层、物理层5个层次比较了当前HWSN跨层协议并对相关协议进行研究,旨在探讨HWSN跨层设计的发展方向,为相关研究工作提供一定的参考和借鉴.The integration of the heterogeneous network as Ubiquitous Network emerges in response to the continuous development of information technology.Heterogeneous wireless sensor networks（HWSN）,which has some heterogeneity features on node,link and protocol,has been widely used in many fields.In order to further improve the overall performance of HWSN,the cross-layer design has been an important way of protocol design nowadays.However,the research on the cross-layer protocol for HWSN still remains at the initial stage and there is no practical use of it for HWSN.This paper analyzes the purpose and methods of cross-layer design,compares the present cross-layer protocol from the aspects of the application layer,transport layer,network layer,MAC layer and physical layer.It also discusses its future development and the existing problems,which should have much significance to the future studies in this field.
