Abstract: For large-scale mobile ad hoc networks,hierarchical protocol can enhance the stability of network topological structure and reduce communication relay. This paper proposed a hybrid method to construct a largcscale MANET hic rarchical structure, so as to enhance the stabhty of network topological structure. This method combines dynamic node's Multi-feature fusion with Gibbs Random Field-Maximum a Posterior. Simulation experiments show that our algorithm performs better in the stability of hierarchical structure than the existing algorithms.
