Abstract
Sensor networks using mobile robots have recently been proposed to deal with data communication in disruption tolerant networks (DTNs) where an instantaneous end-to-end path between a source and destination may not exist. In such network scenarios, a node should move to deliver data to the destination. In this paper, we study adaptive formations of mobile robots based on the knowledge of network topology held by each node. Different node formations are applied when nodes have neighboring, clustering, or perfect information of network. Node formations also depend on traffic patterns, e.g., single and multiples packets per event. We introduce a straight line formation called pipeline for delivering multiple packets continuously. The benefit of controlled mobility in DTNs is validated through the ns–2 simulation tool by comparing with the ideal cases.
