Mobile Content-Centric Networking (CCN)

Project overview

Although most of the research on how to take advantage of CCN cache capabilities has been centered on non-mobile environments leading to results that give good indication of what can be achieved, the need of investigating mobile scenarios is starting to call the attention of the research community. The main problems we are addressing are how to take advantage of cache nodes when the nodes are moving possibly in and out of the service range of any given node and how to forward packets efficiently in non-infrastructure mobile environments.

 

What is CCN ?

Content centric networking proposes a new paradigm in our view of communications. One important feature of this new architecture is the use of cache memory at the network level (see Fig 1). This cache is designed to store transit information for a determined period of time and it is believed that this capability will help to increase the network performance, particularly in a growing video streaming scenario.

Potential benefits

  • Reduced congestion and better delivery speed.
  • Simpler configuration of network devices.
  • Network security at data level.
