Abstract

A method for delivering data frames from a source device (602) to a Zigbee end device, ZED, (550) via a Zigbee router device, ZR, (510), comprises, at the ZR, receiving (605), a data request and at least one data block (615) from a transmission window of a plurality of data blocks from the source device (602), and placing the received data block in a queue for transmission; receiving (609) a data request from the ZED; transmitting, the received data block from the queue, to the ZED and receiving an acknowledgement from the ZED. The method further includes receiving a re-transmission of the transmission window of the data blocks (625, 630, 635) from the source device (602); and dropping, at least one re-transmitted data block (630), previously received and transmitted by the ZR, and transmitting, by the ZR, the remaining re-transmitted data block(s) (625, 635), to the ZED.
