The adaptive routing protocol recently proposed by researchers for opportunistic networks often makes an assumption that when each node makes an intelligent decision of choosing a best forwarder node to route its messages, the chosen forwarder will often have a large buffer storage and will always altruistically devote its resources for forwarding those(More)
Intermittently connected opportunistic networks experience frequent disconnections and shorter contact durations. Therefore routing of packets towards their destinations needs to be handled from various points of view. Predictability and connectedness are two information that mobile nodes, which participate in an opportunistic content distribution,(More)

Predicting future contact opportunities in opportunistic networks can assist mobile nodes to make intelligent decisions on efficient content forwarding and can greatly improve the message delivery ratio. But predicting future contacts has to depend on the past history of contacts and then naturally a question arises on how valid is the use of past history(More)
