| 1. A method for optimizing data traffic in an ad-hoc established device network including a central controller and a set of
terminal devices, the method comprising:
monitoring the data traffic in order to determine, with respect to a specific terminal device, which amount of the data traffic
from said specific terminal device and/or to said specific terminal device is routed via said central controller;
checking whether said specific terminal device is capable of acting as a controller if at least a predefined amount of the
data traffic from said specific terminal device and/or to said specific terminal device is routed via said central controller;
and
performing a handover of the control functionality in order to establish said specific terminal device as the new central
controller if said specific terminal device is capable of acting as a controller.
