In-network caching in information-centric networks for different applications: A survey

Abstract

AbstractInformation-Centric Networks (ICNs) have become a promising paradigm for the future Internet instead of host-based communication. In this network, content-oriented data and in-network caching are two key properties, which have brought tremendous benefits to many challenging networks by improving the distribution and retrieval of content. The content is cached along the reversed delivery path, on-path caching and off-path caching. Generally, the existing caching approaches in Information-Centric Networks mainly consider the key characteristics of the content (to decide which content is to be cached), the network (to determine the appropriate time for caching), the nodes (to determine where content should reside), etc. This paper presents a comprehensive survey of in-network caching of ICN schemes (also known as ICN-based caching) in many network applications. Thus, a detailed analysis of the existing caching approaches in several network applications, such as MANET, VANET, IoT, and WSN, is given. This survey also provides a taxonomy for caching policies according to some feature-based approaches and highlights the trends and evaluation problems in these areas. Finally, the challenging research directions in different applications are also pointed out in this subject.
