Cache Migration Protocol for Information-Centric Networks

The Information-Centric Network (ICN) is regarded as a promising network paradigm as it can reduce network congestion and data retrieval latency with the help of its intra-network caching, especially in regard to the Internet of Things (IoT). In multiple caches systems, a global caching gain can be obtained by coded caching during the cache placement stage between the content originator and cache routers. Additionally, the use of a distributed, simultaneous transmission technique enabled and dynamic context supported protocol can provide extra performance gains. In this paper, we propose a Cache Migration Protocol (CMP) to support the dynamic simultaneous transmission during the content delivery stage between cache routers and consumers in a distributed manner. The design of CMP is evaluated via simulations using OPNET. The simulations show that CMP is able to select appropriate nodes for supporting simultaneous transmissions when the network context is changed. Meanwhile, it is demonstrated that CMP outperforms the traditional ICN content delivery method Named Data Networking (NDN) in terms of reduced number of transmissions, the average end-to-end delay and average throughput.
