Title: Peon: Privacy-enhanced Opportunistic Networks With Applications In Assistive Environments
Author: Vakde, Gauri
Abstract: Opportunistic Networking holds a great deal of potential for making communications easier and more flexible in pervasive assistive environments. However, security and privacy must be addressed to make these communications acceptable with respect to protecting patient privacy. We propose Privacy-Enhanced Opportunistic Networking (PEON), a system for using opportunistic networking in privacy-preserving way. PEON uses concepts from anonymous communications, re-routing messages through groups of peer nodes to hide the relation between the sources and destinations. We describe a set of protocols that explore a practical range of trade-offs between privacy and communication costs by modifying how closely the protocol adheres to the optimal predicted path. We also present the results of extensive trace-based simulation experiments that allow us to both compare between our proposed protocols and observe the costs of increasing the number of groups and intermediate nodes in a path.
