Optimizing the Topology of Bluetooth Wireless Personal Area Networks

Abstract— In this paper, we address the problem of determining an optimal topology for Bluetooth Wireless Personal Area Networks (BT-WPANs). In BT-WPANs, multiple communication channels are available, thanks to the use of a frequency hopping technique. The way network nodes are grouped to share the same channel, and which nodes are selected to bridge traffic from a channel to another, has a significant impact on the capacity and the throughput of the system, as well as the nodes’ battery lifetime. The determination of an optimal topology is thus extremely important; nevertheless, to the best of our knowledge, this problem is tackled here for the first time. Our optimization approach is based on a model derived from constraints that are specific to the BT-WPAN technology, but the abstraction of the model is such that it can be related to the more general field of ad hoc networking. By using a min-max formulation, we find the optimal topology that provides full network connecti...
