Bandwidth-based QoS-aware Multisource Architecture for Information-Centric Wireless Multihop Networks

Information-Centric Networking (ICN) is one of the representative architectures for Future Internet that focuses on content rather than IP address. Different from traditional TCP/IP networking, any node that caching content can respond to a request for the content. This property makes it convenient that multiple providers deliver different chunks of a content to a requester concurrently, which can offer more reliable network services and better load balancing. However, it may impact quality of service (QoS) because traditional end-to-end QoS control cannot be performed in this scenario. In this paper, a Bandwidth-based QoS-aware Multisource Architecture (BQMA) is proposed for Information-Centric wireless multihop networks, which performs QoS control for multisource routing, forwarding, reservation procedure, and provider selection functions. Simulation results demonstrate the effectiveness of the proposed architecture.
