By a News Reporter-Staff News Editor at Journal of Engineering -- TEXAS INSTRUMENTS INCORPORATED (Dallas, TX) has been issued patent number 9253110, according to news reporting originating out of Alexandria, Virginia, by VerticalNews editors.
The patent's inventor is Ho, Jin-Meng (Plano, TX).
This patent was filed on December 15, 2011 and was published online on February 2, 2016.
From the background information supplied by the inventors, news correspondents obtained the following quote: "Existing networks do not allow nodes to request or allow a hub to grant best-effort scheduled access, wherein an allocation interval is scheduled for a node ahead of time and then granted on a best-efforts basis in real time. Instead, existing networks use strictly scheduled access intervals.
"An example system for providing a unified framework of non-contention access methods, including scheduled, polled and posted access, and for providing different levels of tradeoffs between power consumption and strictly scheduled medium access for use in a Body Area Network (BAN) or in any other network or system, is described in U.S. patent application Ser. No. 12/697,105, filed Jan. 29, 2010, and titled 'Access and Power Management for Centralized Networks' the disclosure of which is hereby incorporated in its entirety herein."
Supplementing the background information on this patent, VerticalNews reporters also obtained the inventor's summary information for this patent: "Nodes may request, and a hub may provide, tentative, but not committed, scheduled allocations. These allocations are referred to herein as unscheduled bilink allocations, in which data traffic is transferred between the nodes and the hub on a best-effort basis. Such tentative allocations will be available if the network of the hub still has enough bandwidth when the scheduled time arrives, but will be shifted or reduced otherwise. The access method used to obtain unscheduled bilink allocations is referred to as best-effort scheduled access or, interchangeably, unscheduled access.
"Embodiments of the invention provide flexible and simple allocation intervals to nodes in a network. A unified framework of non-contention access methods, including scheduled, polled and posted access, enables different levels of medium access. A node may use best-effort scheduled access for an allocation on a communication medium. The best-effort scheduled access may be a one-periodic (1-periodic) allocation in which an allocation interval reoccurs in every beacon period. The 1-periodic allocation is suitable for high-duty cycle periodic or quasi-periodic traffic. The best-effort scheduled access may also be a multi-periodic (m-periodic) allocation that reoccurs over a longer interval, such as every m beacon periods (where m>1). The m-periodic allocation is suitable for low duty cycle periodic or quasi-periodic traffic. The 1-periodic and m-periodic allocations may be used for bilink traffic. For the situation wherein multiple users require allocation intervals on the same channel or with the same hub, a round-robin allocation format may be used in which each node is assigned an allocation interval in turn.
"A poll frame or data frame may be used by a hub to indicate if a node is allowed to use the earlier tentatively scheduled allocation interval. The hub sends the node a poll identifying a polled allocation that designates an interval in the actually granted best-effort scheduled allocation. The hub may provide the expected or scheduled allocation interval. Alternatively, the hub may designate an allocation interval that is shifted in time or reduced/expanded in duration. Once a polled allocation starts, the node may upload frames to be received and acknowledged by the hub."
