Ac-Qos-Fs: Ant Colony Based Qos-Aware Forwarding Strategy For Routing In Named Data Networking

This paper proposes a new QoS-aware forwarding strategy for Named Data Networking. Borrowing techniques from the ant colony optimization, the proposed strategy, which is called Ant colony based QoS-aware forwarding strategy (AC-QoS-FS), makes full use of both forward and backward ants to rank interfaces. Forward and backward ants (Interest and Data packets) probe real-time network QoS parameters to update the interfaces ranking in order to select the best one for forwarding the incoming Interests. The effectiveness of AC-QoS-FS is validated through ndnSIM simulation.
