Abstract: Describing briefly the characteristics of a mobile ad-hoc network or MANET and comparing them with related works, a new definition of time degree was given in view of the highly dynamic topology and absence of any fixed infrastructure in MANET. Analyzing the link relationship between two adjacent nodes, a network model based on the link life of the two nodes was set up. Some predicting techniques were investigated and used for the cost of each link so as to gain a more stable link. A distributed clustering algorithm is therefore proposed on the basis of a mobility prediction scheme. Simulation results showed that the algorithm proposed outperforms HD and LCC clustering algorithms.
