摘要:
A mobile node (400) capable of establishing an ad hoc network routing is disclosed. The mobile node comprises a transmitting/receiving unit (426) for communicating with other communication unit and a routing request generator (422) for generating a routing request message for requiring an ad hoc network routing. The mobile node further comprises: an address storage (427) for storing an address of the mobile node (400) and an address of a receiving node; a random number generator (430) for generating a random number; a certificate issuing unit (440) for issuing a certificate of the mobile node (400); a digital signature creator (450) for creating a digital signature of the mobile node (400); and a controller (424) for transmitting/receiving the routing request message accompanied by the address of the mobile node, the address of the receiving node, the random number, the certificate and the digital signature via the transmitting/receiving unit, according to an ad hoc network protocol.

摘要:
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.
摘要:
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.
摘要:
A process for producing an arylamine is provided which is characterized by reacting an aromatic halogen compound with an aromatic amine in the presence of an organic salt selected from specific pyridinium salts, imidazolium salts and quaternary onium salts, a copper catalyst, and a base. Thus, the reaction of even an aromatic halogen compound substituted by an electron-donating group proceeds efficiently, and an inexpensive chlorinated aromatic compound or brominated aromatic compound is usable, and an arylamine, in particular a triarylamine or diarylamine, having a high purity can be produced at low cost.
摘要:
In a wireless packet transmission system that includes multiple wireless basestations and one or more wireless terminals belonging to one of the wireless basestations, transmission trees extending from two or more wireless basestations as root stations are used. Each of the wireless basestations has a tree table configured to record the root stations in association with the ID information about the transmission trees. When receiving a packet, each of the wireless basestations determines the transmission tree to be used for the packet transmission, and transmits the packet to a next node along the determined transmission tree.
摘要:
A common mode choke coil adapted for surface mount applications minimized in overall size (particularly in height), with an improved bonding coefficient. This common mode choke coil has a structure comprising a ferrite core consisting of a winding core and two square planar flanges with recesses formed therein, the square planar flanges being formed integrally on each end of a winding core thereof, a pair of external electrodes disposed on the square planar flanges, a plurality of windings wound about the winding core of the ferrite core and connected by thermal bonding to the external electrodes at the recesses provided in the left and right sides of each flange, and a ferrite plate adhesively bonded to the outermost surface of the windings to join the two flanges at both ends of the ferrite core, without an adhesive bonding to the flanges themselves. As a result, a closed magnetic circuit structure of a cubic component having a high rate of bonding coefficient is obtained.
