ICN-based cache-aware routing scheme in MSN

With the growing requirements of digital media by Mobile Social Network (MSN) users, an effective routing scheme plays an important role to transmit the interest requests and the requested contents of users. Due to the native support of Information-Centric Networking (ICN) for mobility, we propose a cache-aware routing scheme in MSN based on ICN paradigm. In the proposed scheme, Interest Routing scheme (IR) is devised based on the social regularity with respect to the proposed interest metrics among nodes, which are obtained by exploiting the content names. To transfer data packets back to the interest requesters, Data Routing scheme (DR) is devised based on the proposed closeness metrics among nodes. An In-network Caching scheme (IC) is devised based on the proposed friendship metrics among nodes to respond to the forthcoming requests, and it can get the shorter response latency than the traditional MSN routing schemes. Simulation results show that the proposed scheme has higher message delivery ratio and lower network overhead than other existing ones.
