In wireless communication using links with neighbor wireless devices, a wireless device calculates ratios of throughput to maximum throughput for the links and calculates the costs of the links using the calculated ratios. Then the wireless device finds, for each destination, a route in which the sum of such calculated link costs is the minimum, and sends a packet to the destination using the route. As a consequence, routing can be done according to an isotonic, easy-to-implement routing protocol.

The use of a wireless interface is dynamically changeable according to connection states of stations belonging to access points. Therefore, limited wireless interfaces are efficiently utilized without requiring operation in which the user conducts a complex setting operation. First, connection states of stations belonging to access points are measured. Based on information of the connection states, the connection destination of a wireless connection unit of an access point under consideration is changed over between an access point and a station.

摘要:
Disconnection of communication is prevented and a connecting relation is maintained between radio devices even when a communication channel is dynamically switched. Accordingly, when a first radio device switches a communication channel used for radio communication with a second radio device, the first radio device firstly switches to a simultaneously-connectable channel capable of a simultaneous communication with an original channel, and then switches to a destination channel.
摘要:
The route maintenance unit outputs a period setting request to the period setting unit when the communication unit normally receives a Hello packet for the first time. The period setting unit sets a link connection confirmation period in response to the period setting request and outputs the set period to the route maintenance unit. The route maintenance unit maintains a radio link between the radio device in which the route maintenance unit is provided and an adjacent device upon receiving a data packet other than a Hello packet from the adjacent radio device even if a Hello packet is not received in the link connection confirmation period. Consequently, route disconnection or switching occurs less often.

An electrophoretic display sheet comprising a display layer, a first electrode, and second electrodes. The display layer has a plurality of reservoir portions filled with a dispersion liquid containing particles. Each of the plurality of reservoir portions has predetermined positions. When an electric field having a direction is generated by applying a voltage to between the first electrode and the second electrodes, the particles are locally gathered to the predetermined positions of each of the plurality of reservoir portions so as to make rows of the particles along the direction of the electric field in the dispersion liquid. The electrophoretic display sheet is capable of exhibiting both superior responsiveness (responsibility) and superior color display performance with high contrast in changing a display color.
