- Abstract
- A method of retransmitting a packet for low-power wireless sensor communications of a coordinator in a sensor network is provided. The method includes receiving packets from a plurality of sensor devices during a plurality of guaranteed time slots (GTSs) of a Contention Free Period (CFP) which are allocated to the respective sensor devices; checking whether there is an error in each of the received packets; generating one GTS Bulk ACK frame that contains pieces of ACK information to be transmitted to the respective sensor devices, according to the error check results; and transmitting the generated GTS Bulk ACK frame to the plurality of sensor devices.
