Routing Protocols for Improving Survivability of Scatternet Routes

Abstract: Bluetooth is one of the popular short-range wireless communication technologies, and most of the portable Bluetooth devices are battery-driven. Thus, the survivability of routes in a Bluetooth scatternet is becoming a crucial issue. The survivability of a scatternet route depends on not only the residual energy of the battery of the Bluetooth device but also the mobility of the Bluetooth devices on the route. In this paper, the survivability of a scatternet route on basis of the energy and mobility of Bluetooth devices are explored. Moreover, a quality measure, Q-value, for the Bluetooth device is proposed for evaluating the impact of a device onto the survivability of a scatternet route. Then, based on the quality measure, three approaches that can establish highly survivable scatternet routes are proposed. Finally, the simulation study was conducted to evaluate the performance of the three approaches. The simulation results show that the three approaches can improve survivability of scatternet routes with the cost of computing overhead during route establishment.
