ELC: Edge Linked Caching for content updating in information-centric Internet of Things

Internet of things (IoT) has enabled every thing around us to have an Internet connection. In the future, IoT will generate more content than any other network. It is estimated that about 27 billion Internet enabled devices will connect to the Internet. For IoT, the current IP-based architecture, also known as Host-centric architecture, is not suitable. Therefore, a clean slate architecture is required to provide solutions to the problem. The researchers have recently proposed an appropriate architecture for this purpose, known as Information-Centric Network (ICN). ICN would potentially become the future Internet architecture as it has the ability to manage this huge number of IoT devices and their content. ICN's in-network caching functionality is very useful for IoT, as it reduces the overhead of the publisher with respect to content access. This paper proposes an IoT caching strategy based on ICN that will effectively cache IoT data as well as update and evict content based on its freshness values.
