Abstract
A method of selecting one of a plurality of candidate devices (1-6) forming at least part of a wireless personal area network (WPAN) to be a controller of the WPAN. For each candidate device (1-6), distances between that candidate device and other devices of the WPAN are assessed. A centrally located one (3) of the candidate devices is selected to be the controller, taking said distances into account. The residual battery energy of the candidate devices may also be taken into account.
