  • Patent number: 8271058
    Abstract: A first device communicates with a wireless network that includes nodes that are active for predefined activation times and that are at least partially dormant when not active. The communication method includes identifying a start of communication via a message that exceeds a maximum activation time of nodes on the wireless network by a factor N, where N is equal to at least a maximum number of frequencies on the wireless network, and exchanging information with a second device comprising a node on the wireless network that is within a transmission range of the first device, where the information is exchanged following the message and includes frequency hopping data for the second device.

  • Publication number: 20110298598
    Abstract: A system and method for low latency sensor network schedules transmissions in the network is described herein. In some embodiments of the technology, information associated with at least two network devices is received. Each network device can be associated with at least one event in a sequence of events. A first schedule entry in a schedule can be determined for each of the at least two network devices based on the received information. At least a part of the schedule can be transmitted to each of the at least two network devices.
