In a wireless communication system that includes a plurality of wireless terminals each of which has a first device type and transmits data to a destination, and a plurality of wireless relay apparatuses each of which has a second device type and relays the data that is received in wireless communication with each wireless terminal to the destination, each of the plurality of wireless terminals detects a wireless frame, receives data contained in the wireless frame when the detected wireless frame contains information that represents the first device type, and avoids receiving data contained in the wireless frame when the detected wireless frame contains information that represents the second device type.

Wireless communication system, wireless relay apparatus, and data receiving method for wireless terminal

A transfer destination selecting method conducted by a communication device includes selecting, when the communication device stores, according to a destination, pieces of information indicating a plurality of other communication devices that are candidates for a transfer destination of data, one of the other communication devices to be the transfer destination from among the candidates on the basis of a number of destinations in a routing table used for controlling a data transfer and stored in each of the plurality of other communication devices.

Transfer destination selecting method, communication device and recording medium

A method executed by a wireless communication device used in a wireless ad hoc network includes: designating a bit in a loop detection array added to a received frame in accordance with identification information of the wireless communication device; deciding that a route in which the received frame has been transmitted is not a loop when the bit designated in the loop detection array is not used; deciding that the route is a loop when the bit designated in the loop detection array is used; updating the bit designated in the loop detection array to a state of being used and transmitting the received frame toward a destination node when it is decided that the route is not a loop; and returning the received frame to an adjacent node that is a local transmission source of the received frame when it is decided that the route is a loop.
