    An energy efficient scatternet formation algorithm for Bluetooth-based sensor networks
    (IEEE, 2005-02) Saginbekov, Sain; Körpeoğlu, İbrahim
    In this paper, we propose an energy-efficient scatternet formation algorithm for Bluetooth based sensor networks. The algorithm is based on first computing a shortest path tree from the base station to all sensor nodes and then solving the degree constraint problem so that the degree of each node in the network is not greater than seven, which is a Bluetooth constaint. In this way, less amount of energy is spent in each round of communication in the sensor network. The algorithm also tries to balance the load evenly on the high-energy consuming nodes which are the nodes that are close to the base station. In this way, the lifetime of the first dying node is also prolonged. We obtained promising results in the simulations. © 2005 IEEE.

    SF-Devil: Distributed Bluetooth scatternet formation algorithm based on device and link characteristics
    (IEEE, 2003-06-07) Pamuk, Canan; Karaşan, Ezhan
    Bluetooth has become very popular owing to the fact that it is a promising ad-hoc networking technology for short ranges. Although construction and operation of piconets is well defined in Bluetooth specifications, there is no unique standard for scatternet formation and operation. In this paper, we propose a distributed Bluetooth scatternet formation algorithm based on device and link characteristics (SF-DeviL). SF-DeviL handles energy efficiency using class devices and the received signal strength. SF-DeviL forms scatternets that are robust to position changes and battery depletions. © 2003 IEEE.
