US 2009/0245159 A1 · System and method for node-clustering and multi-hop routing in wideband wireless ad-hoc networks

Abstract

An ad-hoc network system for computing a proposed number of node-clusters that enable a relative threshold data rate. The ad-hoc network system includes a source terminal, a destination terminal, a plurality of relay terminals, and a cluster determination engine. The source terminal sends a network communication to a destination terminal via a plurality of relay terminals. The cluster determination engine computes a threshold data rate, C, for a number of hops, N, based on a transmission power constraint. The cluster determination engine determines a proposed route for the wireless communication from the source terminal to the destination terminal according to the threshold data rate, C.
