When two opportunistic network peers encounter, utility functions are generally employed to select the messages that have to be exchanged, with the purpose of maximizing message delivery probability and reduce congestion. These functions compute weighted sums of various parameters, like centrality, similarity, and trust. Most of the existing solutions statically compute the weights based on offline...
When two nodes in an opportunistic network meet, a utility function is generally employed to select the data that have to be exchanged between them, in order to maximize the chance of message delivery and to minimize congestion. The utility function computes weighted sums of various parameters, such as node centrality, similarity, trust, etc. Most of the existing solutions pre-compute the weights...
