Time Synchronization In A Network

View page
US Patent:
7558294, Jul 7, 2009
Filed:
Jan 24, 2006
Appl. No.:
11/339293

George M. Peponides - Encinitas CA,
Sherman Leon Gavette - Camas WA,
Assignee:
Intellon Corporation - Ocala FL
International Classification:
H04J 3/06
H04J 3/14
H04L 12/413
G08B 1/08
US Classification:
370509, 370236, 370445, 340538
Abstract:
A method and corresponding system for communicating between stations in a network is presented. The method includes providing repeated beacon transmissions from a coordinator station for coordinating transmissions among the stations; transmitting a signal from a first station and receiving the signal at a second station; and performing one or both of: generating the signal based on a local clock at the first station and time adjustment information in a beacon transmission received by the first station, and sampling the signal at sample times based on a local clock at the second station and time adjustment information in a beacon transmission received by the second station.

Delayed Acknowledgements For Low-Overhead Communication In A Network

US Patent:
2011026, Nov 3, 2011
Filed:
Apr 12, 2011
Appl. No.:
13/085344
Inventors:
Srinivas Katar - Gainesville FL,
Manjunath Krishnam - Gainesville FL,
International Classification:
H04L 27/00
US Classification:
375259
Abstract:
Communicating between stations over a shared medium comprises: receiving a first waveform at a first station transmitted over the shared medium from a second station, the first waveform including a payload having multiple segments, and during reception of a first segment of the payload, initiating processing of one or more segments of the payload received before the first segment of the payload to generate acknowledgement information that specifies which of one or more segments of the payload including the one or more processed segments have been correctly decoded by the first station; transmitting a second waveform from the first station over the shared medium, the second waveform including the acknowledgement information; and transmitting a third waveform from the first station over the shared medium, after transmitting the second waveform, the third waveform including acknowledgement information that specifies which of one or more segments of the payload including the first segment of the payload have been correctly decoded by the first station.

Communicating Schedule And Network Information In A Powerline Network

US Patent:
2007002, Feb 1, 2007
Filed:
Jul 24, 2006
Appl. No.:
11/492487
Inventors:
Neal Riedel - Carlsbad CA,
Yiorgos Peponides - Encinitas CA,
James Petranovich - La Jolla CA,
Lawrence Yonge - Ocala FL,
Srinivas Katar - Gainesville FL,
Deepak Ayyagari - Vancouver WA,
Sherman Gavette - Camas WA,
Wai Chan - Vancouver WA,
International Classification:
H04J 1/16
H04J 3/06
US Classification:
370252000, 370516000
Abstract:
There is provided a powerline network that includes a number of stations including a central coordinator for coordinating transmissions of each of the stations. The central coordinator includes a system clock and a network timer and is configurable to transmit a number of network timer values. Each of the network timer values can be transmitted by the central coordinator in one of a number of beacons. Each of the other stations is configurable to utilize the network timer values and a corresponding number of local timer values to estimate a frequency error between the system clock and a local clock and an offset between the network timer and a local timer. Each of the other stations is further configurable to utilize the frequency error and the offset to synchronize the local timer to the network timer.

Bandwidth Management In A Powerline Network

US Patent:
2007002, Feb 1, 2007
Filed:
Jul 24, 2006
Appl. No.:
11/492505
Inventors:
Neal Riedel - Carlsbad CA,
Yiorgos Peponides - Encinitas CA,
James Petranovich - La Jolla CA,
Lawrence Yonge - Ocala FL,
Srinivas Katar - Gainesville FL,
Deepak Ayyagari - Vancouver WA,
Sherman Gavette - Camas WA,
Wai Chan - Vancouver WA,
International Classification:
H04L 12/413
US Classification:
370445000, 370252000
Abstract:
There is provided a powerline network that includes a number of stations including a central coordinator for coordinating transmissions of each of the stations. Each of the stations is configurable to generate one or more tone maps for communicating with each of the other stations in the powerline network. Each tone map includes a set of tones to be used on a communication link between two of the stations. Each tone map further includes a unique set of modulation methods for each tone. Each of the stations is further configurable to generate a default tone map for communicating with each of the other stations, where the default tone map is valid for all portions of a powerline cycle. Each of the stations is further configurable to monitor its bandwidth needs and to request additional bandwidth from the central coordinator.

US Patent:
2007005, Mar 15, 2007
Filed:
May 25, 2006
Appl. No.:
11/420432
Inventors:
Deepak Ayyagari - Vancouver WA,
Wai-Chung Chan - Vancouver WA,
Sherman Gavette - Camas WA,
Neal Riedel - Carlsbad CA,
Srinivas Katar - Ocala FL,
International Classification:
H04L 12/413
US Classification:
370445000
Abstract:
Methods, devices, and systems are provided wherein connections are requested with a connection specification that is based on whether the request is between a higher layer entity and a lower layer entity, between two stations, or between a station and a central coordinator. The connection specification may include QOS parameters and MAC parameters.

Establishing A Unique End-To-End Management Key

US Patent:
2008029, Dec 4, 2008
Filed:
Jan 7, 2008
Appl. No.:
11/970339
Inventors:
SRINIVAS KATAR - Gainesville FL,

International Classification:
H04L 9/32
H04L 9/14
US Classification:
380258, 380277
Abstract:
Systems and methods for communicating and authenticating end-to-end management keys to stations to facilitate communications between stations in the network. A nonce based upon a pseudo-random number generated by the station(s) can be included with the end-to-end management key (EMK). The station(s) can compare the nonce to the generated pseudo-random number to authenticate the EMK.

Assignee:
Intellon Corporation - Ocala FL
International Classification:
H04L 9/00
US Classification:
