Scheduled service periods in wireless mesh networks

摘要

A method, apparatus and computer program product in which a computer system functions as a mesh point (MP) and provides scheduled service periods in wireless mesh networks is presented. The MP enters a light sleep mode. The MP determines peers of itself and determines beacons for the peers of itself. The MP then enters an Awake state for the beacons of its peers.

主权项

1. A computer-implemented method in which a computer system functions as a mesh point (MP) and said MP performs operations comprising:
entering a light sleep mode; determining peer MPs of said MP; determining beacons for said peer MPs of said MP; wherein said light sleep mode comprises a mode wherein said MP is in an awake state for the beacons for all peers, whereas an MP in sleep mode is not required to wake up for beacons for all peers and wherein an awake period for a MP starts before a first beacon of said MP during said awake period; entering, by said MP, an Awake state for said beacons of said peer MPs, and wherein an amount of time an MP must be awake is reduced since said awake window for each MP starts before said beacons of said peer MPs such that traffic can be received by all MPs in a single awake beacon; and wherein said awake state has a duration defined by an awake window element and wherein said awake window element include a Max PSP length field containing a value of a maximum length of a peer service period.
