Method of operating a telecommunications network

摘要

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.
