ABSTRACT:
One embodiment of the present invention provides a system for performing wireless slot adaptation with reservations in a time division multiple access (TDMA) network where time is divided into time slots in repeated frames. During operation, the system receives a vector from a neighbor node, wherein a respective element in the vector indicates received signal quality for a corresponding time slot in a frame with respect to that neighbor node. Next, the system updates a record which indicates the received signal quality for all the time slots within a frame for the neighbor node based on the received vector. The system then determines a transmission threshold for a time slot with respect to a neighbor node based on the record. Subsequently, the system transmits a packet destined for the neighbor node in an outbound queue if the record indicates that the received signal quality in an upcoming slot is better than the transmission threshold.
