There are many wireless sensor network applications that need to operate in the face of lossy or disconnect-prone links. In these situations, traditional MANET protocols are inadequate and higher layer protocols that require continuous end-to-end connectivity will fail. The IEEE Delay Tolerant Networking Research Group (DTNRG) investigates architectural and protocol design principles that provide for communication in performance-challenged environments. This demonstration shows how some of the ideas out DTNRG can be adopted for sensor networks, specifically Bundles as the basic unit of communication, and Custody Transfer as a policy for when to delete data.
