  • Patent number: 8767766
    Abstract: A method and apparatus are described including identifying a channel that a decentralized network is using for communications and identifying a station that is a member of the decentralized network to monitor data transmission activity over the identified channel. Also described are a method and apparatus for a station to transmit data over a communication medium of a decentralized network including monitoring the communication medium, determining if the communication medium is idle, transmitting data if the communication medium is idle and if the station has a data to transmit and adjusting a slot count and a service ring configuration if the medium is busy. Further described are a method and apparatus including monitoring a communication channel used by a decentralized network, determining a number of available idle time slots between two successive frame transmissions initiated by different stations, updating a service ring, adjusting a number of stations and adjusting a slot count.

  • Patent number: 8737425
    Abstract: A method and apparatus are described for gaining access to a communication medium in a contention-based network, including determining a slot count based on a number of stations in the contention-based network, adjusting the slot count, initiating a frame transmission when the slot count reaches a predetermined value and wherein said number of stations and an address queue are adjusted to reflect one of a priority and traffic patterns. Further, a method and apparatus are described for gaining access to a communication medium in a contention-based network, including receiving a slot count based on a number of stations in the contention-based network, adjusting the slot count, initiating a frame transmission when the slot count reaches a predetermined value and wherein said number of stations and an address queue are adjusted to reflect a priority.

  • Publication number: 20090219992
    Abstract: A method for controlling transmission of video data in a network, including: transmitting video data to a receiver via the network; receiving channel parameter information measured by the receiver; applying a predictive function to the channel parameter information to compensate for delay times in receiving the channel parameter information from the receiver, and generating a feedback function; and adjusting the video data to be transmitted in response to the feedback function to compensate for network conditions.
