Abstract
It is provided a method, including: monitoring if a first cluster head of a first cluster of first communication devices has disappeared, wherein an apparatus performing the method has access to the first cluster enabling a device-to-device communication of the apparatus with at least one of the first communication devices; and, if it is monitored that the first cluster head has disappeared: detecting a second cluster head of a second cluster of second communication devices, wherein the second cluster head is different from the first cluster head, and the second cluster enables the device-to-device communication between at least two of the second communication devices; and requesting an access to the second cluster for the device-to-device communication.
