Profile-Cast: Behavior-Aware Mobile Networking
Wei-jen Hsu, Debojyoti Dutta, Ahmed Helmy · 2008
In this paper we advocate a service paradigm,profile-cast, within the communication framework of delay tolerant networks (DTN) (K. Fall, 2003). This novel approach leverages the behavioral patterns of mobile network users for delivering messages to a sub-group of users as defined by theirprofiles(e.g., interest, social affiliation, etc.). We study large data sets of usermobilityprofilesand present a case-study ofmobilityprofile-castwith asimilarity-basedforwarding protocol. We show that behavior-aware protocol design has a great potential - we reduce the total number of transmissions to 45% of flooding under 92% delivery success rate, or to only 3% transmissions of flooding under 61% delivery success rate. It also leads to shorter delay (at least 30% less) as compared to a random transmission protocol.
