Abstract: An embodiment of the invention relates to a communication node (CN, N1-N4) capable of communicating with other nodes in a communication system (10) according to a given communication sequence (S). The communication node comprises an analysis unit (110) configured to determine the optimal position of its communication node inside the communication sequence (S) as well as the corresponding optimal predecessor node.

Abstract: An embodiment of the invention relates to a method of carrying out a handover process. After receiving a handover message (HOM(13)) that indicates the initiation of the handover process with respect to a moving node (13), a handover control node (20) addresses its next token (T(21)) to the moving node (13) and not to its formerly allocated downstream node (21) in its original wireless token ring system (2). In case that the moving node (13) receives said token (T(21)) and sends thereafter an acknowledgement to the handover control node (20) and an own token (T) to its allocated downstream node (21) in the enlarged wireless token ring system (2), the handover process is deemed to be completed and the moving node (13) forms the newly allocated downstream node to the handover control node (20) in the enlarged wireless token ring system (2).

Abstract: The invention relates inter alia to a method of operating a communication system (10). Each communication node (11, 12, 13, 14) of the communication system (10) preferably tracks a successful reception of data signals (D) and requests a switch and/or switches from a currently used communication channel (C1) to another communication channel (C2-C6) in case that no successful receptions were made within a given maximum time interval.

Abstract: The invention discloses a method for sending real-time sensitive data using a transmitter for a multi channel communication system, wherein the communication system has n sub-channels, wherein n is greater than 1, wherein the sub-channels are spatially different and/or the sub-channels have different frequencies. The method has the steps of receiving information about the channel state of the n sub-channels, receiving information about the number of statistically independent sub-channels m, wherein m is less than or equal to n, and receiving data intended to be sent.
