The authors deal with the problem of streaming multiple video streams between pairs of nodes in a multi-hop wireless ad hoc network. The nodes are static, know their locations, and are synchronized (via GPS). They introduce a new interference model that uses variable interference radiuses. They present an algorithm for computing a frequency assignment and a schedule whose goal is to maximize throughput over all the video streams. In addition, they developed a localized flow-control mechanism to stabilize the queue lengths. They simulated traffic scheduled by the algorithm using OMNET++/MixiM (i.e., physical SINR interference model with 802.11g) to test whether the computed throughput is achieved. The results of the simulation show that the computed solution is SINR-feasible and achieves predictable stable throughputs.
