Efficient Neighbor Discovery in RFID based devices over resource-constrained DTN networks

In this paper we consider Delay Tolerant Network (DTN) as a technology to implement a future network in a People Centric Networking paradigm, using Active RFID carried by people that exchange information with each other. We propose a novel and real Neighbor Discovery (ND) phase on active RFID based DTN using Open Beacon devices. In particular, we propose a solution using the Sift distribution on a probabilistic persistent approach called Sift-Persistent. We simulated P-Persistent, Aloha and our solution using our customized Java simulator. We implemented Sift-Persistent and P-Persistent on Open-Beacon devices, comparing the simulation results and test-beds. Moreover, simulations and real testbed show a coherent behavior validating our proposal in the RFID context. Performance evaluations have been tested in terms of discovered neighbors.
