Abstract
The present invention relates to a protocol accelerator module for a data transmission protocol level of a transceiver, particularly but not exclusively for rapid forwarding of data packets in wireless sensor networks using the time-division multiple access method according to the IEEE 802.15.4 standard. The invention also relates to a method of transceiver operation for rapid forwarding of data packets, likewise particularly, but not exclusively, in wireless sensor networks using the time-division multiple access method according to the IEEE 802.15.4 standard. The core of the invention is a reference table which stores references from identifiers of second transceivers to identifiers of third transceivers as well as references from specific messages to identifiers of third transceivers. A transceiver can check during reception of a data packet whether it is a data packet to be forwarded, and can take appropriate precautions for rapid sending of a data packet to be forwarded. This allows real-time conditions of many applications to be met.
