Geographic interest forwarding in NDN-based wireless sensor networks

Abstract

Named Data Networking (NDN) has emerged as a new and promising information-centric architecture for the future Internet that is also gaining momentum in Wireless Sensors Networks (WSNs) as an alternative paradigm to traditional IP. However, the main solutions in current works lack energy efficient design to meet the severely limited energy resources in WSNs. Moreover, the NDN architecture cannot natively allow devices to transmit unsolicited data, like alarms or status changes unless to properly modify the semantics of exchanged packets and the forwarding strategy. In this paper, we propose a Geographic Interest Forwarding scheme called GIF in short, for NDN-Based WSNs. In this proposal, we added support for push-based WSN traffic. We further extend the scheme with an efficient forwarding techniques in which several energy efficient mechanisms including flooding scope control, broadcast storm avoidance, packet suppression are designed to balance the energy consumption across the network. We extend the ndnSIM to support wireless multihop communication to validate the proposed scheme. Simulation experiments confirm the viability and effectiveness of the proposal.
