Patent number: 8879466Abstract: Provided is a Media Access Control (MAC) technology that may improve a data transmission performance in an asynchronous sensor network. The MAC technology may increase a waked-up time interval of a reception node to thereby continue to receive traffic from a transmission node, and change a frequency band where data is transmitted and received to thereby reduce occurrence of collision. Also, when the wake-up time interval of the reception node is similar to a wake-up time of a neighboring node, the wake-up time interval of the reception node may be moved to another time interval, thereby improving the data transmission performance.Type: GrantFiled: May 18, 2010Date of Patent: November 4, 2014Assignee: Electronics and Telecommunications Research InstituteInventors: Noseong Park, Yoonmee Doh, Jong-Arm Jun

Patent number: 8208401Abstract: Provided is a method of managing addresses of incommunicable nodes in a ZigBee network, and more particularly, a method of managing address values of a plurality of nodes that form a ZigBee network by efficiently withdrawing address values from nodes which are incommunicable for reasons of abnormality. An address management process can be performed using two methods. According to a first method, a parent node withdraws address values of child nodes that do not transmit a hello message for a predetermined period of time. According to a second method, a parent node transmits a periodic or non-periodic request message to child nodes, and the child nodes, which receive the request message, immediately transmit a hello message to the parent node. Then, the parent node withdraws address values of child nodes that do not respond to the request message sent by the parent node more than a predetermined number of times.Type: GrantFiled: September 24, 2007Date of Patent: June 26, 2012Assignee: Electronics and Telecommunications Research InstituteInventors: Noseong Park, Yoonmee Doh, Hyunhak Kim, Sun-Joong Kim, Cheol Sig Pyo
