Abstract: A scheduler for a wireless network including N wireless stations having N bandwidth parameters, respectively, comprises a framing module that generates a schedule frame including schedule slots. An assigning module assigns N sets of TxOps to the N wireless stations based on the N bandwidth parameters, respectively. Each of the schedule slots includes zero or one transmission opportunity (TxOp) for each of the N wireless stations. A polling module polls the N wireless stations based on the TxOps defined in respective ones of the N sets of TxOps.

Abstract: A wireless network according to the present invention includes a plurality of nodes that transmit and receive radio frequency (RF) signals. An access point broadcasts and receives radio frequency (RF) signals, wirelessly communicates with the plurality of nodes, generates a table containing a list nodes operating in the wireless network, and broadcasts the table to the plurality of nodes. The access point also calculates traffic conditions. A first node receives the table determines a hidden status of a second node in the table. The first node communicates directly with the second node if the second node has a not hidden status and communicates with the second node through the access point if the second node has a hidden status.
