摘要： A handover method of a mobile terminal device in a wireless local area network (WLAN) includes a mobile terminal device and at least two wireless access points (APs) which communicate with the mobile terminal device using particular radio resources. The mobile terminal device communicates with a wireless AP via a first radio resource, and receives signals from wireless APs via a second radio resource. The mobile terminal device arranges and stores the signals received from the wireless APs in a certain order of size. The mobile terminal device determines an AP for the handover by sequentially searching the stored APs when intensity of the signal received via the first radio resource is smaller than a predetermined value.

摘要： A location recognition system and method using stereophonic sound, the system having a transmitter and a receiver. The transmitter uses the stereophonic sound and transmits location tracking information of an object. The transmitter includes a sound detector which detects a sound of the object and converts the detected sound to an electrical signal; a data converter which converts the electrical signal converted by the sound detector, to acoustic data; and a first communication interface which transmits the acoustic data converted by the data converter and the location tracking information to the receiver. A user can immediately recognize the location of the transmitter which transmits the location tracking information and is the target of the location tracking. Therefore, the mutual communications between the transmitter and the receiver which receives the location tracking information can be smoothly carried out.

摘要： A communication system having a source node, at least one mobile node, and a router that transmits data packets transmitted from the source node to a corresponding one of the at least one mobile node and multiplexes response signals to the data packets received from the corresponding one of the at least one mobile node to transmit the multiplexed response signals to the source node. The communication system includes: a link monitoring unit which calculates a capacity of a wireless link between the router and the corresponding one of the at least one mobile node; and a congestion control and adjustment unit which adjusts window field values in the response signals according to the calculated capacity. The router transmits the response signals, the response signals including the adjusted window field values to the source node, and the source node sequentially transmits the data packets on the basis of the adjusted window field values.
