Delay tolerant networks can exhibit long phases of complete unconnectedness, where several nodes will not be able to communicate effectively. In those circumstances controlling the movement of helper nodes, that facilitate message exchanges instead of relying on direct communication, can improve network performance. We investigate when controlled movement is beneficial and how helper nodes need to move or position themselves to achieve maximum network performance. Three communication modes on a… CONTINUE READING
