Parasitic Mobility in Sensor Networks Implications - Sensor clusters hitch rides to places where they need to be to optimally: - Measure relevant phenomena - Relay information peer-peer - Dump information into portals - Get recovered or recharged - Rapid diffusion of sensors across an environment - System self-organizes to auto-dispatch nodes to desired regions Innovations and Architecture - Interpretation of Energy Harvesting in mobile networks - Two flavors: - The Tick (e.g., jumps onto a car, attaches magnetically, then disengages) - The Bur (e.g., sticks to passing object, then shakes off) - Contains GPS, RF, basic sensor suite Phoresis Paradiso & Laibowitz
