Appl. No.:

11/101047

Inventors:

Rahul Kopikare - Livermore CA, US
Senthil K. Arumugham - Sunnyvale CA, US
Milind Kopikare - Sunnyvale CA, US

Assignee:

Marvell International Ltd. - Hamilton

International Classification:

H04J 3/16
H04B 7/212
H04L 12/403

US Classification:

370346, 370348, 370449

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.

Assignee:

Marvell International Ltd. - Hamilton

International Classification:

H04J 3/24

US Classification:

370312, 370235, 709242

Abstract:

A first node in a wireless network comprises a transceiver that wirelessly communicates with an access point. A hidden status generator communicates with the transceiver, receives a table comprising a list of nodes in communication with the access point and determines a hidden status of a second node in the table relative to the first node.

International Classification:

H04J 3/24

US Classification:

370312, 370235, 709242

Abstract:

A wireless network comprises a plurality of nodes. An access point wirelessly communicates with the plurality of nodes, generates a table comprising a list of the plurality of nodes, and transmits the table to a first node of the plurality of nodes. The first node determines a hidden status of a second node in the table relative to the first node.

International Classification:

H04J 3/24

US Classification:

370312, 709242

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.
