Design and analysis of context-aware forwarding protocols for opportunistic networks

The new challenges presented by opportunistic networks call for advanced networking solutions, especially for what con- cerns message forwarding. Very promising are those ap- proaches that exploit information on the context the users are surrounded by, like the other users they met, the places they visit, etc. In this work we describe HiBOp, a context- aware forwarding protocol that includes a mechanism for col- lecting and managing context information. We also present an analytical model that can be used as a framework for evaluating the delay under context-aware forwarding proto- cols in which context is built from <tag, value> pairs that characterize each use
