Predictability of human mobility and its impact on forwarding
Pan Hui, Jon Crowcroft · 2008
Pocket switched networks (PSNs), a kind of delay tolerant networks (DTNs), focus on human-to-human communication. In this kind of networks, human mobility determines data delivery opportunity. In this paper, we show that human mobility is well predictable on a day-to-day basis and can much improve forwarding efficiency over oblivious schemes in terms of delivery ratio and delivery cost.
