摘要
Nowadays, Information-Centric Networking (ICN) has been recognized as a promising paradigm in which users retrieve named content with information-centric communication mode rather than finding IP address with host-centric communication mode. Although ICN routing has attracted much attention from researchers, the current proposals cannot effectively and intelligently solve the mobility problem in a self-adaptive and self-organizing manner. In this paper, we introduce Ant Colony Optimization (ACO) into ICN and propose a novel ACO-inspired ICN Routing mechanism with Mobility support (AIRM) to retrieve the content no matter where it moves. At first, a continuous pheromone updating strategy inspired by alcohol volatilization model is devised to conduct the forwarding of interest ant. Secondly, we determine which outgoing interfaces can be used to forward interest ant, propose a computation scheme to obtain the forwarding probability, and select an outgoing interface to forward interest ant by roulette model. Thirdly, the detailed design on AIRM is presented to address mobility while retrieve the closest content copy. Finally, we evaluate the proposed AIRM, and the simulation results show that AIRM not only solves the mobility problem effectively but also has better performance than existent schemes in terms of routing success rate, routing hop count, load balance degree and execution time.
