A Performance Analysis of Content Centric Wireless Networks

Information-Centric Networks (ICNs) are a promising solution to deal with nodes´ mobility and low efficiency in wireless networks because they benefit from the native mobility support. This paper analyzes the performance of a wireless content-centric network implementation. The goal is to identify its main weaknesses and characterize an operating range based on these limitations. To this end, a simplified model of this network was implemented in the ndnSIM simulator. The efficiency of content delivery, delay and network load are shown through simulation from a content consumer perspective. The results show the benefits of content-centric wireless networks, which improves content-delivery efficiency and delay up to 63% and 40%, respectively, in certain scenarios, as well as highlight the impact of contention and collisions that define the broadcast storm problem.
