Mobile nodes are allowed to move around within an intermittent communication environment. A mobile node wirelessly communicates with an access node when approaching the access node, and stores data. The access node stores an action history for each mobile node, and generates a forwarder list in association with a destination node, based on action histories of the mobile nodes. The forwarder list stores one or more identifies each identifying a first mobile node in the order of an arrival probability indicating a probability that the first mobile node succeeds in delivering the data to the destination node. The access node selects second mobile nodes that are to carry the data to the destination node, based on the forwarder list, and transfers the data to one of the second mobile nodes when a communication link is established between the access node and the one of the second mobile nodes. |

1. A system to deliver data in an intermittent communication environment, the system comprising:
a plurality of mobile nodes each allowed to move around within the intermittent communication environment; and a plurality of access nodes each connected to one of a plurality of networks; and an integrated information management database included in one of the plurality of networks, wherein each of the plurality of access nodes is configured to:
wirelessly communicate with one of the plurality of access nodes and the plurality of mobile nodes upon approach to any node, andstore communication data to be delivered to a destination node included in one of the plurality of networks; each of the plurality of access nodes is configured to:
store an action history in association with each of the plurality of mobile nodes, the action history including evaluation information on past transfer of communication data between a mobile node and the plurality of access nodes,generate a forwarder list in association with the destination node, based on action histories of the plurality of mobile nodes, the forwarder list storing one or more forwarder identifiers each identifying a first mobile node, the forward identifiers arranged in an order of an arrival probability indicating a probability that the first mobile node succeeds in delivering the communication data to the destination node, select one or more second mobile nodes that are to carry the communication data to the destination node, based on the forwarder list,transfer the communication data to one of the one or more second mobile nodes when a communication link is established between each access node and the one of the one or more second mobile nodes so that the communication data is delivered to the destination node via the one of the one or more second mobile nodes, the action histories of the plurality of mobile nodes are managed by the integrated information management database; and the action histories managed by the integrated information management database are synchronized, via the plurality of mobile nodes, with the action histories stored in the plurality of access nodes. |
