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.

Abstract translation: 为了优化特设建立的设备网络中的数据业务，监视数据流量以便确定到达和来自特定设备的数据流量的数量是否被中央控制器反映。 应避免反映的数据流，因为它们增加了网络的负载。 如果多于所述数据流量的预定义量被中央控制器反映，并且如果特定设备是具有控制器能力的设备，则执行控制功能的切换以便建立所述特定终端设备作为新的中央控制器 。 因此，减少了反射数据流。
