Abstract

In order to optimize data traffic in an ad-hoc established device network, the data traffic is monitored in order to determine which amount of the data traffic to and from a specific device is reflected by the central controller. Reflected data streams should be avoided because they increase the load of the network. If more than a predefined amount of said data traffic is reflected by the central controller, and if the specific device is a controller-capable device, a handover of the control functionality is performed in order to establish said specific terminal device as the new central controller. Thus, reflected data streams are reduced.
