A channel allocation method for dynamically allocating channels of a plurality of radio interfaces at each access point included in a mesh network is provided. The method includes the steps of (a) acquiring, at each access point, in-node information about the access point itself, and (b) grouping high-traffic access points in a cluster using a same channel set based on the acquired information.
Abstract:
Provided is a mobile communication system capable of determining a communication path to implement fast communication by multihop connection. A mobile communication system (1) comprises a mobile station (10), at least one relay station (30), and a base station (20) and implements packet transmission from the mobile station (10) to the base station (20) through a communication path with an intermediary of at least one relay station (30) or through a communication path without an intermediary of a relay station. The mobile communication system (1) is provided with a communication path determiner for determining a communication path with a largest communication speed or a communication path satisfying a required line quality, based on interference levels of respective signals received at a relay station (30) constituting a communication path between the transmitting station and the receiving station, and at the base station (20).

A wireless communication apparatus is provided. The wireless communication apparatus includes: detection means that detects that there is another wireless communication apparatus around the wireless communication apparatus; comparison means that compares a first reference value managed in the wireless communication apparatus with a second reference value managed in the another wireless communication apparatus; means that corrects the first reference value based on the comparison result; and means that announces the first reference value to the another wireless communication apparatus. Frequencies are set such that a frequency of the wireless communication apparatus becomes same as a frequency of still another wireless communication apparatus to which a radio wave of the wireless communication apparatus does not reach but a radio wave of the another wireless communication apparatus reaches.
Abstract:
A semiconductor memory device comprises: a write circuit including a latch circuit configured by two inverters having a positive side power supply terminal supplied with a first voltage and a negative side power supply terminal supplied with a second voltage; and a write state machine controlling the first and second voltages. When writing data to a memory cell, the first voltage is changed to a second value that is lower than a first value. When writing data to a memory cell, the second voltage is changed to a third value that is lower than the second value. The write state machine lowers the second voltage to an intermediate value between the second value and the third value and, while maintaining this intermediate value, lowers the first voltage from the first value to the second value.
Abstract:
The object is to control interference in a permissible range by applying the CDMA system to signal collision in the conventional CSMA and TDMA base multihop systems and to relax the hidden terminal problem and others to enhance the throughput of the entire system by grouping of channel groups in multihop transmission and by control of transmission based on an interference level from another station. A multihop relay station calculates a desired signal level, for example, from an interference level at its own station of a packet sent from a mobile station, and notifies the mobile station of the desired signal level; and the mobile station calculates a transmission power amount of a packet from the desired signal level, determines whether the packet is transmissible to the station as a source of the desired signal level, and transmits the packet to the source station determined as a packet-transmissible station.
