Abstract
A device includes an interface and Time Division Multiple Access (TDMA) Medium Access Control (MAC) circuitry coupled to the interface. The TDMA MAC circuitry detects a beacon in a frame having a defined frame duration and determines a frame compensation value based on a start time of the frame, a reference start time of the frame, and a number of elapsed frames. A current frame duration value is determined based on the frame compensation value and the defined frame duration.
Claims25
A device, comprising:
- an interface, which, in operation, receives a data stream of a network;
- and
- Time Division Multiple Access (TDMA) Medium Access Control (MAC) circuitry, coupled to the interface, wherein the TDMA MAC circuitry, in operation:
- detects a beacon packet in a frame of the data stream, wherein a frame is a period of time having a defined frame duration;
- determines a frame compensation value based on a start time of the frame, a reference start time of the frame, and a number of elapsed frames;
- and
- determines a current frame duration value based on the determined frame compensation value and the defined frame duration.
A method, comprising:
- detecting, by a node of a Time Division Multiple Access (TDMA) network, a beacon transmitted in a frame, wherein a frame is a period of time having a defined frame duration;
- determining, by the node, a frame compensation value based on a start time of the frame, a reference start time of the frame, and a number of elapsed frames;
- and
- determining, by the node, a current frame duration value based on the frame compensation value and the defined frame duration.
A system, comprising:
- node data processing circuitry, which, in operation, generates data related to a node;
- and
- Time Division Multiple Access (TDMA) Medium Access Control (MAC) circuitry, coupled to the node circuitry, wherein the TDMA MAC circuitry, in operation:
- detects a beacon in a TDMA frame, wherein a frame is a period of time having a defined frame duration;
- determines a frame compensation value based on a start time of the frame, a reference start time of the frame, and a number of elapsed frames;
- and
- determines a current frame duration value based on the frame compensation value and the defined frame duration.
A non-transitory computer-readable medium having contents which cause a node of a Time Division Multiple Access (TDMA) network to perform a method, the method comprising:
- detecting a beacon in a frame, wherein a frame is a period of time having a defined frame duration;
- determining a frame compensation value based on a start time of the frame, a reference start time of the frame, and a number of elapsed frames;
- and
- determining a current frame duration value based on the frame compensation value and the defined frame duration.
