Abstract:
A method for communicating in a network including a coordinator node and a set of leaf nodes transmits periodically, from the coordinator node to the set of leaf nodes, a beacon defining a superframe, wherein the supper frame includes an active period and an inactive period, and wherein the active period includes a first contention access period (CAP-1), a first contention free period (CFP-1), a first group acknowledgement (GACK-1), a second CFP-2, a second GACK-2, and a second CAP-2, and wherein each CFP includes a guaranteed time slot (GTS) assigned to each leaf node. Then, each leaf node transmits to the coordinator node only during the GTS assigned to the leaf node during each CFP.
