     those of the shortest path routing and our previously proposed cooperative routing schemes.

+    Today, most mobile devices are equipped with multiple wireless network interfaces, but are
+    constrained to use only one network at the same time. In this paper, we show that using multiple
+    access networks simultaneously can improve user-perceived QoS and cost- effectiveness. We
+    present a system architecture that exploits the adap- tive forwarding plane of Named Data
+    Networking (CCN/NDN) and implement a system prototype based on the NDN Forwarding
+    Daemon (NFD). More specifically, we propose a set of forwarding strate- gies that use
+    fine-grained application requirements together with interfaces estimation techniques for delay,
+    bandwidth, and packet loss. Our simulation results show that our approach can improve QoS
+    and/or reduce access costs in many wireless scenarios.
