1. A concentrator configured to send signals to and receive signals from a plurality of neck nodes in a TDMA mesh network, wherein each neck node defines a sector of the mesh network which may comprise a plurality of further nodes, the concentrator comprising:
a detecting unit, configured to detect for interruption of transmission between a first node and a second node scheduled in a first time slot; a sector establishing module, configured to establish the sector of an interrupted transmission by identifying the neck node through which at least one of said first node and said second node is scheduled to communicate with the concentrator; a determining module, configured to identify a sector to be checked and to determine whether any nodes in said sector are scheduled to transmit during said first time slot, wherein each sector is successively identified to be checked according to its proximity to the sector of the interrupted transmission, until at least one node scheduled to transmit during said first time slot is found; a scheduling module, configured to determine a different time slot for the transmission from said at least one node found by the determining module; a sending unit, configured to send a signal instructing rescheduling of said transmission to said different time slot. |
