Implementation and Experimental Results of a Raspberry Pi and OLSR Based Wireless Content-Centric Network Testbed

Abstract

The Content Centric Networks (CCN) replaces the IP narrow waist of the Internet architecture by a content layer. When a node wants to access a piece of content, it sends an Interest packet to the network. The network then, using the name of the content for routing, forwards the Interest to one or more copies of the content object. In this paper, we present the implementation of a testbed for CCN. We analyze the performance of Optimized Link State Routing (OLSR) protocol in an indoor scenario. For evaluation we considered throughput, Packet Delivery Ratio (PDR), hop count, delay and jitter metrics. The experimental results show that the nodes in the testbed were communicating smoothly and we got hight values of throughput and PDR and low values of delay and jitter.
