A Shapley Value-Based Forwarding Strategy in Information-Centric Networking

Information Centric Networking (ICN) is a new kind of network architecture centered on content data. The ICN improves the efficiency of data transmission by the longest matching routing mechanism based on the content name prefix of the request interest packets, however, the multipath forwarding performance also resulted in the redundancy of the network content. The existing ICN forwarding strategy does not take into account the selection problem of routings when a content hit multiple Faces. This paper proposes a routing forwarding strategy based on Shapley value. We add a forwarding value table, which is used to calculate the number of content routing and the number of face to forwarding. The table stores the request delay of content routing and the busy degree of the next hop nodes. The content routing number and forwarding nodes of the next hop forwarding are decided by the alliance game. Simulations show that our strategy can improve the cache hit ratio, reduce server load and reduce the average request delay compared with full forwarding strategy, it improves the network performance in total.
