AN EFFICIENT COMBINED CONGESTION HANDLING=--A--cN-:cD~-­ ROUTE MAINTENANCE PROTOCOL FOR DYNAMIC ENVIRONMENT IN BLUETOOTH NETWORK

Bluetooth IS a widespread technology for small wireless networks that permits
Bluetooth devices to construct a multi-hop network called a scatternet. A large
number of connections passing through a single master/ bridge device may create the
problem of congestion in a Bluetooth scatternet. In addition, routing in a multi-hop
dynamic Bluetooth network, where a number of masters and bridges exist, sometimes
creates technical hitches in a scatternet. It has been observed that frequent link
disconnections and a new route construction consume more system resources that
ultimately degrade the performance of the whole network. As, Bluetooth specification
has defined piconet configuration, scatternet configuration has still not been
standardized. The main objective of this thesis is to provide an efficient combined
protocol for scatternet congestion handling and route maintenance. The methodology
contains three parts.
