This paper describes a self-organizing, multihop, mobile radio network which relies on a code-division access scheme for multimedia support. In the proposed network architecture, nodes are organized into nonoverlapping clusters. The clusters are independently controlled, and are dynamically reconfigured as the nodes move. This network architecture has three main advantages. First, it provides spatial reuse of the bandwidth due to node clustering. Second, bandwidth can be shared or reserved in a controlled fashion in each cluster. Finally, the cluster algorithm is robust in the face of topological changes caused by node motion, node failure, and node insertion/removal. Simulation shows that this architecture provides an efficient, stable infrastructure for the integration of different types of traffic in a dynamic radio network.read more

An energy efficient hierarchical clustering algorithm for wireless sensor networks
Seema Bandyopadhyay,E.J. Coyle +1 more
TL;DR: This paper proposes a distributed, randomized clustering algorithm to organize the sensors in a wireless sensor network into clusters, and extends this algorithm to generate a hierarchy of clusterheads and observes that the energy savings increase with the number of levels in the hierarchy.

Highly dynamic Destination-Sequenced Distance-Vector routing (DSDV) for mobile computers
TL;DR: The modifications address some of the previous objections to the use of Bellman-Ford, related to the poor looping properties of such algorithms in the face of broken links and the resulting time dependent nature of the interconnection topology describing the links between the Mobile hosts.
