Abstract:

Content-centric networking(CCN)is a novel network architecture which presents new challenges for the design of routing. Aiming at the characteristics of CCN, a temperature field based routing(TFBR)algorithm was proposed. This scheme introduced the conception of temperature fields in physics into CCN and applied a finite element method(FEM), which is one of numerical analysis techniques, to assign a temperature value to each node of CCN in a distributed way. Simulation results show that TFBR can adequately utilize the cache in CCN nodes and decrease the network average delay while improving the performance of load balancing.

Key words: content-centric networking, routing, cache, temperature field
