Description
Summary:Internet of Things (IoT) has emerged as a novel paradigm that focuses on connecting a large number of devices with the Internet infrastructure. To address the performance requirements of IoT devices, the Content-Centric Networking (CCN) becomes an encouraging future Internet architecture that emphasizes name-based content access, instead of searching for the host-location in the network. The in-network content caching is an essential characteristic for rapid information dissemination and efficient content delivery in the CCN. To this end, a novel content caching scheme has been proposed for comprehensive utilization of the available caching resources. The proposed scheme partitions the CCN-enabled IoT networks hierarchically to reduce content redundancy and excessive cache replacement operations. For content caching decisions, the proposed caching strategy considers normalized distance-based metrics along with dynamic threshold heuristics to improve content retrieval delay by placing the contents near the IoT devices. Extensive simulation analysis on realistic network configurations demonstrates that the proposed caching scheme outperforms the existing competing content placement strategies on performance parameters such as network cache hit-ratio, hop-count, delay, and average network traffic. Thus, the proposed caching scheme becomes more promising for CCN based IoT applications.
