Clustering of the ad hoc networks is an important technique for introducing a hierarchical structure into the network. In the previous work we have proposed an autonomous clustering scheme for highly mobile large ad hoc networks, which is adaptive to change of the network topology. In this scheme, the network is logically divided into sets of mobile nodes(More)
In mobile ad hoc networks, since nodes move around the network, the network topology and the number of neighboring nodes in each node frequently change. Although the number of neighboring nodes in each node and the distance between any two adjacent nodes always change, the transmission range of each node is not changed. Therefore, it is expected that many(More)
Many clustering schemes and hierarchical routing protocols have been proposed in order to manage large-scaled ad hoc networks efficiently. However, there is the possibility that in hierarchical routings based on the clustering scheme a node called a clusterhead which manages the cluster has much overhead because it must handle all the information on the(More)
In order to realize hierarchical routings that should be executed in large-scaled mobile ad hoc networks that vary their topologies considerably with time, we have developed autonomous clustering with high scalability and adaptability. In autonomous clustering, an entire network is divided into disjoint subnetworks (called clusters), and they are maintained(More)
