1. As will be clear in the following, in opportunistic networks the routing and forwarding tasks are strictly intertwined and usually performed at the same time. Therefore, hereafter we use the terms routing and forwarding interchangeably.
2. We do not discuss here opportunistic network applications, as this chapter is mainly centred on the networking and routing aspects of opportunistic networks. The interested readers can find more information about the application aspects on the Haggle project web site: www.haggleproject.org
3. Two weeks seems to be very long, but as we have mentioned before, the Reality network is very sparse. we choose it mainly because it has long experimental period and hence more reliable community structures can be inferred. The evaluations here can serve as a proof of concept of the Bubble algorithm, although the delays are large in this dataset. Delay in other datasets are much lower; for example in Infocom05, the median delay is 3 hours.
4. The update of the ranking has a much lower cost. As we presented in [392], it can be approximatedby a exponential smoothing function of its past contact history.
