Abstract
AD LOC is a novel system for mobile devices to collaboratively tie persistent virtual notes to physical locations. Notes that are relevant to particular locations can be created and then cached using serendipitously formed one-hop wireless ad hoc network connections. The location provides an address to which the information is relevant and devices attempt to keep the information stored at devices which remain close to this address. In simulation experiments, even under conditions of nodal flux, it is possible to retrieve over 90% of the notes that have been stored.
