C. Victoria Priscilla, A. R. Charulatha · 2019
Mobile communication has become an integral part of everybody's life. The global internet traffic is increasing at an alarming rate because of the demand for internet content like web pages, audio files, and videos. The success of the internet is because of the success of various internet applications which is also the reason for growing internet traffic. This has led to redefining the IP stack by allowing the content-centric networking, CCN. CCN is dependent on the caching contents in-network and off-network nodes. There have been various strategies on how to cache the contents. The Quality of Service offered by the providers improves with a proper selection of caching strategy, which helps in increasing the network efficiency by lowering the bandwidth of the network. The selection of an appropriate caching strategy also proves to improve the user's quality of experience. This paper discusses the need, architecture of CCN, the various caching strategies and a comparative study on LCE, LCD, ProbCache and MAGIC caching strategies by running in a common simulation environment.
