O-SPIN: An Opportunistic Data Dissemination Protocol for Folk-Enabled Information System in Least Developed Countries

Abstract

Abstract. Without universal access to the Internet, Least Developed Countries are left by the wayside of the digital revolution. Research is underway to overstep the barrier to the development of information technology services in these areas. In this context, the Folk-IS (Folkenabled Information System) is a new fully decentralized and participatory approach, in which, each individual can transparently perform data management and networking tasks through highly secure, portable, and low-cost storage and computing personal devices, as physically moving, so that global services can finally be delivered by crowd. In this paper, we propose Opportunistic SPIN (O-SPIN), an information dissemination protocol that augments the well-known data-centric energy-aware SPIN (Sensor Protocols for Information via Negotiation) protocol to enable networking facilities for Folk-nodes, by exploiting opportunistic contacts among users. Performance of the proposed solution has been evaluated through simulations carried out in the OMNeT++ framework under different settings. Achieved results demonstrate its effectiveness and efficiency in the information dissemination process.

Epidemic information dissemination controlled by wireless channel awareness

“…In the negotiation-based scheme in [5] the infected nodes, which are about to forward data, poll their neighbors about their residual energy before adjusting their message forwarding probability. Energy-aware routing protocols such as SPIN, LEACH and their descendants [5], [27], [28] can be considered to fall in this category as they achieve broadcast suppression. Similarly, the active publish/subscribe scheme proposed in [23] uses network coding and excludes some nodes from a phase of the 20th IEEE Symposium on Computers and Communication (ISCC) 978-1-4673-7194-0/15/$31.00 ©2015 IEEE dissemination process.…”
