摘要:
Channel assignment for access points (APs) in a wireless network includes determining a bottleneck client in an interference relationship, and determining a channel assignment for the APs that maximizes a normalized throughput of the bottleneck client. The normalized throughput is assigned to the bottleneck client, and the bottleneck client is assigned to a fixed set.

An apparatus for inputting a user password, includes an interface receiving a command. Further, the apparatus for inputting the user password includes a control unit setting a target based on the command from the interface, receiving and storing a password character, and determining that authentication is successes only when the set target and the password character are positioned at a same coordinate on a skin image. Furthermore, the apparatus for inputting the user password includes a display unit connected to the interface to display the skin image of the interface that is transmitted from the control unit.

A method and an apparatus for estimating a location of a terminal are provided. The method includes: receiving at least one base station signal from each of at least one base station; computing received signal information with respect to the received signal; and estimating the location of the terminal based on signal transmission direction information associated with the base station and the computed received signal information. The present invention can accurately estimate the location of the terminal based on directional information of base station signals.

The present invention relates to a method for providing Social Network Service (SNS) on the Internet and a system using the same. The present invention is characterized by creating a user tag list constructed with tags that are acquired by a user terminal; forming a social network between the user and other users, based on tags of the user tag list; and creating a diary based on the user tag list and social network associated with tags of the user tag list.While the present invention enables a user to create a diary about one's own life, the present invention provides a social network service (SNS) by utilizing tagging information in the created diary to form a new social network with people or specialists who have the same interests.
