Abstract: A communication device conforming with plural communication standards and having a storage storing a plurality of virtual stacks each having an application program and communication program that implements a protocol stack for communication by the application program. An executor executes the virtual stacks, and a switching controller switches the virtual stacks to be executed by performing a first processing in which at least one part of at least one of the virtual stacks is read from storage and stored into a memory of, and executed by, the executor. Then, in accordance with free capacity in the memory, at least one part of at least one of the virtual stacks executed in the first processing is deleted from memory. In a second processing at least one part of at least one of the virtual stacks is read from the storage and stored into the memory of, and executed by, the executor.

Abstract: An information setting method for a setting device includes the following processes. A first certificate and identification information are obtained from a wireless device to be caused to join a wireless network managed by a management device. The first certificate certifies that the wireless device is a formal wireless device and includes a first public key. The identification information is information that identifies the wireless device. A second certificate is obtained from the management device. The second certificate certifies that the management device is a formal management device and includes a second public key. Apparatus information required for the wireless device to join the wireless network is encoded using the first public key and is output to the wireless device. Management information including the apparatus information and the identification information associated with the apparatus information is encoded using the second public key and is output to the management device.

Abstract: A communication system constructs a communication network using a hopping pattern designated in a router advertisement between a wireless communication device that transmits the router advertisement designating the hopping pattern of channel hopping and an opposite party communication device that receives the router advertisement. The wireless communication device comprises a receiver configured to receive a router advertisement transmitted from another wireless communication device, a generator configured to generate the hopping pattern that does not use the same channel at the same time with respect to a hopping pattern that is designated by the router advertisement received by the receiver, and a transmitter configured to transmit the router advertisement that designates the hopping pattern generated by the generator.
