摘　　要：移动Ad hoc网络是由移动节点组成的无线移动通信网络,它具有动态拓扑、无线通信的特点,但又易受到各种安全威胁。规模较大的移动Ad hoc网络可以用分簇的方法来减少路由和控制开销,并提高网络的可扩充性。综合分析了以安全为部分或全部目的的移动Ad hoc网络分簇方法研究的最新进展。首先分析了移动Ad hoc网络的特点、体系结构和面临的安全威胁,然后将较大规模移动Ad hoc网络的安全分簇方法分为3个重要方面:认证模型、信任度量和不良节点发现。对每个方面的一些典型方案进行了分类论述和综合比较。最后指出了下一步研究中应当着重考虑的问题。Mobile ad hoc networks composed of mobile wireless nodes,are particularly vulnerable due to their features of open medium and dynamic changing topology. Clustering is effective in reducing the spending on routing and control and improving the scalability in large mobile ad hoc networks. This paper surveyed the state of the art in secure cluste- ring of mobile ad hoc networks. Firstly, the characters, proposed architectures and security threats of mobile ad hoc net- works were analyzed. Secondly, secure clustering schemes were reviewed according to authentication model, evaluation of trust and identification of malicious nodes. We also made a comparison and discussion of their respective merits and faults. Finally,we also presented the challenges which are still worth to further research in this area.
