Location Aware Route Maintenance Protocols for the Mobile Bluetooth Radio Networks

Bluetooth is a low-cost, low-power and short range communication technology, which operates in 2.4 GHz ISM band. The important research issues in Bluetooth are scatternet formation and routing, since nodes can arrive and depart at arbitrary time. In this paper, novel route maintenance algorithms are proposed for the Bluetooth scatternet that supports mobility of the nodes. Our protocols guarantee the connectivity among nodes and reconstruct the routes dynamically by taking their location information. Besides, we propose how to reduce the number of hops and to form the shortest route between the source and the destination due to addition of nodes. Performance analysis of our work shows that it outperforms in terms of end to end transmission delay, bandwidth consumption and route maintenance as compared to similar Bluetooth routing protocols.
