A packet scheduling method and apparatus which allows multiple flows that require data transmission to the same output port of a network device such as a router to fairly share bandwidth. The packet scheduling method includes calculating an expected time of arrival of a (k+1)-th packet subsequent to a currently input k-th packet of individual flows by use of bandwidth allocated fairly to each of the flows and a length of the k-th packet; in response to the arrival of the (k+1)-th packet, comparing the expected time of arrival of the (k+1)-th packet to an actual time of arrival of the (k+1)-th packet; and scheduling the (k+1)-th packet of each flow according to the comparison result.

A packet scheduling apparatus and method to fairly share network bandwidth between multiple subscribers and to fairly share the bandwidth allocated to each subscriber between multiple flows are provided. The packet scheduling method includes calculating first bandwidth for each subscriber to fairly share total bandwidth set for the transmission of packets between multiple subscribers; calculating second bandwidth for each flow to fairly share the first bandwidth between one or more flows that belong to each of the multiple subscribers; and scheduling a packet of each of the one or more flows based on the second bandwidth.

A high-speed content inspection apparatus for minimizing system overhead is provided. The high-speed content inspection apparatus extracts content in unit of sub-pattern by inspecting a payload of a packet in units of sub-pattern, and extract target content by inspecting a correlation between the extracted sub-patterns. If a sub-pattern present at the end of a payload is smaller than a predetermined unit of a sub-pattern, position information of the sub-pattern at the end of the payload is rolled back and the correlation is inspected. Accordingly, without having to add another hardware or high-performance hardware, target content can be efficiently detected in real time.

Disclosed are an apparatus and a method for smart energy management by controlling power consumption. Power consumption information is collected from one or more electrical device groups with a smart meter and electrical devices connected through gateways. When the method estimates that the power consumption will be larger than a threshold value, a control command is outputted to a load controller connected through the gateway and power consumption of electrical devices that belong to the electrical device using group is remotely controlled. According to an embodiment of the present invention, an energy company that produces and supplies energy can supply energy depending on a consumer's demand by using current facilities because the present invention can collect remotely energy consumption, analyze energy consumption patterns, and control automatically the energy consumption of electrical devices installed in a customer's area. The consumer who consumes energy can save the energy consumption and the charge of the energy consumption.

Disclosed herein are an apparatus and method for detecting the survival status of a living thing. The apparatus for detecting the survival status of a living thing includes a tilt sensor, a determination unit, and a communication unit. The tilt sensor is attached to a target living thing, and detects minute vibrations generated by the motion of the target living thing. The determination unit determines the survival status of the target living thing for a preset update period based on the minute vibrations. The communication unit sends an update packet including determination results of the determination unit to an outside.

Provided are an apparatus and method for asset tracking based on a ubiquitous sensor network (USN) using a motion sensing. The apparatus may include: a motion sensing manager to receive motion sensing information from a sensor; a filtering processor to filter the motion sensing information based on a filtering parameter and to determine whether a motion occurs based on the filtered motion sensing information; and a location information update (LU) manager to perform LU depending on whether the motion occurs.
