Advanced Efficiency and Stability Combined Weight Based Distributed Clustering Algorithm in MANET

A mobile ad-hoc network is a kind of autonomic network composed only of mobile nodes. The range of its availability is being expanded because of development of communication technology and terminal devices. However, since the nodes participating in network have mobility by themselves, the network topology has dynamic characteristics, compared with the existing fixed network, giving lots of influences on network performances. Therefore, this paper proposes a combined 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. The proposed algorithm can optimize network performances in dynamic MANET environment and minimize energy consumption by improving the problems of efficiency and stability the existing clustering algorithms are facing with.
