摘　　要：移动自组网MANET(Mobile Ad-hoc NETworks)的分级结构包括两层分级结构和多层分级结构MHS(Multi-layer Hierarchical Structure)。虽然MHS具有更好的可扩展性,但也存在着结构稳定性较差和结构维护开销较大等问题。针对上述问题,提出一种基于MANET的多层分级结构MMHS(MANET based Multi-layer Hierarchical Structure)。首先对MMHS进行设计,然后对MMHS的分群策略进行研究,最后对MHS和MMHS的性能进行仿真分析。仿真结果表明:MMHS既提高了结构稳定性,又降低了结构维护开销,说明MMHS要优于MHS。The hierarchical structure of mobile ad-hoc networks （MANET）includes two-layer hierarchical structure and multi-layer hierarchical structure （MHS ）.Although MHS has better scalability,but it also has problems such as poor structure stability and large structure maintenance overheads.Aiming at the problems mentioned above,we propose a MANET-based multi-layer hierarchical structure （MMHS）.First,we design the MMHS.Secondly,we study the clustering scheme of MMHS.Finally,we analyse the performances of MHS and MMHS through simulation.Simulation result shows that the MMHS improves the structure stability and reduces the structure maintenance overheads,which indicates that the MMHS outperforms the MHS.
