A mobile ad-hoc network (MANET) is different from a wired network in that it is composed of various mobile nodes, which make the network's topology change unpredictably. Also, those communicate in cooperation with mobile nodes without manager nodes, which control and mediate the mobility of all nodes for stable routing. Therefore, this paper proposes a weight-based distribution clustering algorithm with hierarchical structure that can maintain topology of MANET as stable as possible, thereby optimizing network performance and making efficient resource allocation for mobile nodes. In the proposal algorithm, the initialization overhead has been decreased by allowing clusters to form locally. Furthermore, through applying the concept of pre-clusterhead and distributed gateway, the frequency of re-clustering during maintenance has been decreased, improving its stability compared to traditional clustering algorithms. The results of the simulation showed that the suggested methods enhanced stability and efficiency compared to the traditional methods.
