Abstract
Official abstract text for this publication.
Systems and methods are provided for adjusting time in a synchronized network by a central device on the network. Each device on the network provided current time, hopping pattern, time slot duration, and an absolute slot number. Devices on the network synchronized to communicate on a repeating schedule of time slots. The central device receives an updated time and determines a time difference between the updated time and the current time. The current time is adjusted in integer multiples of the hopping pattern length up to the time difference. The absolute slot number is updated based on the number of time slots in the adjusted time difference. The updated absolute slot number is propagated to other devices on the network. In turn, these other devices may also propagate the updated absolute slot number.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for adjusting time in a synchronized network by a node on the network, wherein the node is provided a current time, a hopping pattern, a time slot duration, and an absolute slot number, comprising: receiving an updated time; determining a time difference by comparing the updated time to the current time; determining an adjusted time difference, wherein the adjusted time difference is an integer multiple of a product of a hopping pattern le…
