Outline of a cenralised multihop ad hoc wireless network

A concept of a multihop ad hoc network and associated algorithms for adaptive clustering in wireless ad hoc networks are presented in this paper. The algorithms take into account the connectivity of the stations as well as the quality of service agreements. It is shown how the network can be extended over several clusters by the introduction of so-called "forwarding" stations. These forwarders interconnect the clusters and enable multihop connections of users roaming in different clusters. A solution is presented to ensure, as far as possible, an interconnection of clusters by means of the clustering algorithm.
