Buffer Management Policies in Opportunistic Networks

Opportunistic networks are one of the most interesting evolutions of Mobile Ad hoc NETworks (MANETs), where the link between pair nodes is disrupted frequently. The forwarding opportunities of messages in such networks usually are limited because the "Continuous" path between a sender and a destination does not exist. Messages are delivered to their intended destination hop-by-hop in a "Store-carry-forward" manner. Then, the problem of how to schedule and drop the messages in buffer become more important and challengeable due to the unpredictable mobility of nodes, short contact durations between pair nodes, finite storage carried by nodes and so on.
