The Problem of Bluetooth Pollution and Accelerating Connectivity in Bluetooth Ad-Hoc Networks

This paper investigates a real-world problem termed "Bluetooth (BTH) pollution", which is expected to become commonplace as the mass deployment of BTH devices continues. BTH pollution is caused by the presence of a large number of noncooperating BTH devices within the same radio coverage area, which beyond introducing radio interference, also affect each other\´s basic BTH operations such as discovery, paging and connection setup. The overall result can be a significant slow-down in BTH networking operations, e.g. ad-hoc network formation and healing. We believe the effect of BTH pollution is largely ignored in the BTH ad-hoc networking literature. In this paper we provide an insight on the causes of this problem, as well as simulation and experimental results that illustrate it. Finally, we propose a solution to accelerate BTH ad-hoc networking based on the use of the class of device (CoD) information specified in the BTH standard
