摘要:
Provided are a channel management method and a channel selection method for a wireless node in a wireless ad-hoc network. The channel management method includes the steps of: (a) when a current mode is a first mode, performing channel selection using a method for evenly distributing a channel within an interference range; and (b) when the current mode is a second mode, performing channel selection based on a channel switching probability. According to the method, by preventing a channel change from being continuously repeated in a wireless ad-hoc network using multi-channel multi-interface, it is possible to prevent data transmission delay and network performance deterioration.

A drum-type washing machine, and tub and gasket cleaning methods are provided. The drum-type washing machine may include a tub mounted in a cabinet such that a wash water is supplied into the tub, a drum rotatably mounted in the tub such that laundry may be put into the drum, a motor that rotates the drum, and a controller that controls a driving of the motor such that, when the drum is rotated, the wash water supplied into the tub reaches an upper part of an inner circumferential surface of the tub so as to clean the inner circumferential surface of the tub and the gasket.

A drum-type washing machine that is capable of easily cleaning a tub (110) and a tub cleaning method of the same are disclosed. A drum-type washing machine that is capable of cleaning a gasket (140) along with cleaning of the tub and a gasket cleaning method of the same are also disclosed. The drum-type washing machine includes a tub (110) mounted in a cabinet (101) such that wash water is supplied into a tub (110), a drum (106) rotatably mounted in the tub (110) such that laundry is put into the drum (106), a motor (104) for rotating the drum (106), and a control unit (160) for controlling the driving of the motor (104) such that, when the drum (106) is rotated, the wash water supplied into the tub (110) reaches the upper part of the inner circumferential surface of the tub (110) so as to clean the inner circumferential surface of the tub (110).
摘要:
A portable terminal to provide social network service using human body communication includes a human body communication unit to transmit or receive data through a human body, a memory unit to store at least one of social data, user data, reference data, and any additional data collected, a contact object identifying unit to identify a contact object by using the data received by the human body communication unit, and a pattern analyzing unit to analyze a pattern of contact with the contact object using the data stored in the memory unit. A method for providing social network service using human body communication includes sensing a human body contact, identifying a contact object, and analyzing a pattern of contact with the contact object using at least one of social data, user data, reference data and any additional data collected.
