Radio communication device, radio communication system, congestion control method, and record medium
First Claim
1. A radio communication device that communicates with other radio communication devices that are communication partners, comprising:
- a first detection unit that detects moving states of said other radio communication devices;
a second detection unit that detects a moving state of its own device;
a third detection unit that detects a congestion level of communication between said other radio communication devices or a congestion level of communication between said other radio communication devices and said own device;
a transmission unit that transmits a radio signal from said own device to said other communication devices; and
a control unit that controls said transmission unit to transmit the radio signal based on the moving states of said other radio communication devices, the moving state of said own device, and said congestion level.

Abstract
A radio communication device that communicates with other radio communication devices that become communication partners includes first detection means that detects moving states of said other radio communication devices; second detection means that detects a moving state of its own device; third detection means that detects a congestion level of communication between said other radio communication devices or a congestion level of communication between said other radio communication devices and said own device; transmission means that transmits a radio signal from said own device to said other communication devices; and control means that controls said transmission means to transmit the radio signal based on the moving states of said other radio communication devices, the moving state of said own device, and said congestion level.

14. A congestion control method for a radio communication device that communicates with other radio communication devices that are communication partners, comprising:
-
detecting moving states of said other radio communication devices; detecting a moving state of its own device; detecting a congestion level of communication between said other radio communication devices or a congestion level of communication between said other radio communication devices and said own device; transmitting a radio signal from said own device to said other communication devices; and controlling transmission of the radio signal based on the moving states of said other radio communication devices, the moving state of said own device, and said congestion level.

15. A non-transitory computer readable record medium on which a program that causes a computer to execute procedures is recorded, the procedures comprising:
-
a first detection procedure that detects moving states of said other radio communication devices that are communication partners; a second detection procedure that detects a moving state of said computer; a third detection procedure that detects a congestion level of communication between said other radio communication devices or a congestion level of communication between said other radio communication devices and said computer; a transmission procedure that transmits a radio signal from said computer to said other communication devices; and a control procedure that controls transmission of said radio signal based on the moving states of said other radio communication devices, the moving state of said computer, and said congestion level.
