为解决移动自组织网络中分簇存在的恶意簇首和簇首不稳定问题，通过在簇首选择中引入节点品质度量模型和分布式TA选择机制，提出了一种移动自组织网络安全分簇算法。该算法能生成适应不同通信模式、通信距离和移动速度的稳定簇结构，保持可信权威机构TA成员的相对稳定性。仿真分析表明：SCAQM能抵御外部恶意节点的入侵和内部合谋节点的威胁。相比其他分簇算法，SCAQM能有效抑制节点的恶意行为，以较小的算法控制开销生成更稳定的分簇结构。

Secure clustering algorithm based on quality measurement for mobile Ad hoc networks

To deal with the problems of the malicious and unstable cluster headers in the mobile ad hoc networks, the nodes quality measure model and distributing TA choice mechanism were adopted and a secure clustering algorithm based on quality measurement (SCAQM) for mobile ad hoc networks presented. SCAQM can generate the stable cluster structure and maintain relatively stable numbers of TA (trusted authority) adapt to the dynamic network topology. This clustering algorithm can accommodate different communication modes, communication distance and nodes movement. Simulation results show that SCAQM can effectively resist malicious nodes based on the adjustability of node's quality, and that the efficiency of SCAQM is better than other clustering algorithms such as least ID algorithm and WCA algorithm, which is suitable to the tactical mobile ad hoc networks of setting up the reliable hierarchy based on clustering.
