Communication device

A communication connection method executed by a communication device including a storage part storing a history of a failure in connection to another communication device, the communication device forming a communication network with the other communication device, the communication connection method comprising:

• performing search for the other communication device existing therearound;
• performing determination whether or not to connect to the other communication device on a basis of the history of the failure in connection to the other communication device found in the search;
• and
• performing the search again in a case where it is determined not to connect to the other communication device. while executing a connection process of connecting to the other communication device in a case where it is determined to connect to the other communication device and, when the connection process fails, performing update of the history of the failure in connection to the other communication device and performing the search again.

A non-transitory computer-readable medium storing a program comprising instructions for causing a computer configuring a communication device forming a communication network with another communication device to functions as:

• a storage part configured to store a history of a failure in connection to the other communication device;
• a searching part configured to perform search for the other communication device existing therearound;
• a connection availability determination part configured to perform determination whether or not to connect to the other communication device on a basis of the history of the failure in connection to the other communication device found in the search;
• and
• a connection control part configured to:
• cause the searching part to perform the search again when it is determined not to connect to the other communication device;
• while execute a connection process of connecting to the other communication device when it is determined to connect to the other communication device;
• and when the connection process fails, perform update of the history of the failure in connection to the other communication device and cause the searching part to perform the search again.
