Patent number: 9400191Abstract: A method for transmitting, storing and managing data by compressing data packets to be transmitted and received over an advanced metering infrastructure (AMI) network with low-capacity memory and low-transfer rate. A number of transmission packets may be reduced using at least one of a bitmap interval algorithm that assigns a bitmap value to each interval, thereby reducing a number of request packets, a repeated-bitmap interval algorithm that represents sequential data values as bitmap values by toggling a bit value between 0 and 1 in each data value when a change occurs in the sequential data values, and a run-length encoding algorithm that compresses data by encoding run length of sequential identical data.Type: GrantFiled: April 26, 2013Date of Patent: July 26, 2016Assignee: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTEInventors: Hyun-Hak Kim, Tae-Wook Heo, Kwang-Soo Kim, Jong-Arm Jun
