Wireless communication device, wireless communication system, wireless communication method, and computer program product

A wireless communication system comprising:

• an aggregation device that aggregates data, and
• a plurality of wireless communication devices, wherein
• the aggregation device and the wireless communication devices are connected to a network,
• each of the wireless communication devices includes:
• a communication control unit that transmits and receives data to and from a first wireless communication device;
• and
• a determination unit that calculates transmission and reception information based on a transmission and reception result of the data, and variation of received signal intensity of the data, and that determines whether to maintain connection to the first wireless communication device based on the transmission and reception information and the variation, and
• when the transmission and reception information is less than a first threshold, the determination unit determines to switch the connection to the first wireless communication device to connection to a second wireless communication device, and when the transmission and reception information is equal to or more than the first threshold, and the variation is larger than a second threshold, the determination unit determines to maintain the connection to the first wireless communication device, and
• the communication control unit controls communication according to a determination result of the determination unit.

A computer program product having a non-transitory computer readable medium including programmed instructions, wherein the instructions, when executed by a computer, cause the computer to function as:

• a communication control unit that transmits and receives data to and from a first wireless communication device;
• and
• a determination unit that calculates transmission and reception information based on a transmission and reception result of the data, and variation of received signal intensity of the data, and that determines whether to maintain connection to the first wireless communication device based on the transmission and reception information and the variation, wherein
• when the transmission and reception information is less than a first threshold, the determination unit determines to switch the connection to the first wireless communication device to connection to a second wireless communication device, and when the transmission and reception information is equal to or more than the first threshold, and the variation is larger than a second threshold, the determination unit determines to maintain the connection to the first wireless communication device, and
• the communication control unit controls communication according to a determination result of the determination unit.
