Coordinated information collection system, coordinated information collection method, and program

A coordinated information collection system comprising a management server and a plurality of information terminals which are connected via a communication network, wherein

• the management server has:
• a terminal state management unit that manages state information transmitted from the information terminals and including information on an information terminal and a user associated with each of the information terminals;
• and
• a network configuration management unit that selects adjacent information terminals of the information terminals, based on the state information of each of the information terminals managed by the terminal state management unit, and calculates a connection link, which is a network for interconnecting the adjacent information terminals, and
• the information terminals respectively have:
• an internal state management unit that manages the state information of the information terminal;
• an adjacent management unit that manages information on adjacent information terminals selected by the network configuration management unit;
• and
• a messaging unit that stores a message acquired from an adjacent information terminal via the connection link and a message inputted by the user in a message box opened to other information terminals, and manages these messages, and wherein
• the network configuration management unit calculates a degree of dissimilarity among information terminals based on the state information of each information terminal, and calculates a first type connection link that creates a connection link sequentially from an information terminal having a lowest degree of dissimilarity, and a second type connection link which is created stochastically based on the degree of dissimilarity.
