Routing in delay tolerant networks (DTNs) is a challenge since it must handle network partitioning, long delays, and dynamic topology. Meanwhile, routing protocols of the traditional mobile ad hoc networks (MANETs) cannot work well due to the failure of its assumption that most network connections are available. In this paper, we propose a hop count based(More)
—Delay and Disruption Tolerant Networks (DTNs) may lack continuous network connectivity. Routing in DTNs is thus a challenge since it must handle network partitioning, long delays, and dynamic topology. Meanwhile, routing protocols of the traditional Mobile Ad hoc NETworks (MANETs) cannot work well due to the failure of its assumption that most network(More)
—Delay Tolerant Networks are characterized by frequent network topology partition, limited resource, extremely high latency, etc. Consequently successful deliveries of messages in such networks face great challenges. In this paper, by capturing the temporary clusters, we timely use the temporary end-to-end paths to directly and successfully deliver(More)
The non-existence of an end-to-end path poses a challenge in adapting the traditional routing algorithms to delay tolerant networks (DTNs). This paper innovatively puts forward the concept of " time-slice " to make full use of the respective advantages of single copy strategy and multiple-copy strategy thus getting a right balance between high message(More)
