WIRELESS NETWORK SYSTEM AND PACKET RELAYING TERMINAL DEVICE, AND PACKET RELAYING METHOD IN THE SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a wireless network system capable of avoiding wasteful consumption of wireless resources by designating a relaying direction and its region in broadcasting.

SOLUTION: The wireless network system distributes data to surrounding terminals by applying multi-stage relaying to a broadcast signal. A sender terminal 1 designates a parameter including a relying direction (valid angular range) and its region (effective width) in broadcasting and a packet relaying terminal device 2 receiving the parameter discriminates whether or not its own present location information is included in the region denoted by the parameter to discriminate the necessity of relaying of a received broadcast packet.
