A Novel Solution To Minimize The Interest Flooding And To Improve The Content-Store Performance For Ndn-Based Wireless Sensor Networks

Information-centric networking (ICN) provides an alternative to the traditional end-to-end communication model of the current Internet architecture by focusing on information dissemination and information retrieval. Named Data Networking (NDN) is one of the candidates that implements the idea of ICN on a practical level. Implementing NDN in wireless sensor networks (WSNs) will bring all the benefits of NDN to WSNs, making them more efficient. By applying the NDN paradigm directly to wireless multi-hop ad-hoc networks, various drawbacks are observed, such as packet flooding due to the broadcast nature of the wireless channel. To cope with these problems, in this paper, we propose an Interest called the accumulation-based forwarding scheme, as well as a novel content store architecture to increase its efficiency in terms of storing and searching data packets. We have performed extensive simulations using the ndnSIM simulator. Experimental results showed that the proposed scheme performs better when compared to another scheme in terms of the total number of Interests, the content store search time, and the network lifetime.
