Abstract: In a communication apparatus on a network where communication apparatuses perform direct communication with each other, a network management apparatus for managing the network based on message information transmitted and received on the network is determined. When the communication apparatus itself is determined as the network management apparatus, the apparatus collects information indicating device capabilities from other communication apparatuses. On the other hand, the communication apparatus receives information indicating device capabilities from another communication apparatus when the other communication apparatus is determined as the network management apparatus.

Abstract: In a remote control system, when a user directs a host device of a portable type toward target devices for search and specification, a search signal including a unique identifier (UID) is transmitted from a directional antenna. Each of the target devices stores the UID included in the received search signal in a memory unit, and transmits a response signal including device information on itself from an antenna. The host device identifies one of the target devices based on the device information included in the response signal, runs a control program for the identified target device, and displays an operation screen on a display unit. When the user instructs the remote operation on the operation screen, the host device transmits a remote control signal including the UID from the omni-directional antenna.
