Abstract
Methods and access devices for collecting data from sensors of a wireless sensor network include transmitting a broadcast signal by a master device which currently collects the data and detected by other access devices. Handover of data collection control from the current master access device to an alternate access device is initiated based on a result of the detection. A handover request signal is received at the master device and a handover reply is signaled to a source device of the handover request signal. The handover reply indicates the time at which data collection is handed over from the current master access device to the source device. Thereby, the master device can be changed in a flexible manner based on current environmental conditions.
