Bluetooth is a short-range wireless technology designed to connect various low power, resource constrained devices such as cameras, cell-phones, laptops, handhelds, etc. Devices form autonomous ad hoc networks of up to 8 active devices, referred to as piconets.Piconets may be inter-connected by one or more bridge devices to form a scatternet.Research in Bluetooth today is largely based on scatternet models and includes optimal algorithms for scatternet formation, scheduling and traffic engineering.The bridges are the most important part of the scatternet as they bear the responsibility of a switch -relaying traffic from one piconet to another.Generally, the implicit assumption made is that the bridge already exists or that the bridge can be formed in some manner.However, the issues surrounding the bridge are complex and involve the masters of more than one piconet.In this paper we propose a framework -The Bridge Establishment, Adaptation and Maintenance (BEAM) -for bridge formation, maintenance, List of Tables Page 1.1 Comparison of Various technologies currently available. . . . . . . . 4 2.1 Bluetooth Packet Types. . . . .
