Data Freshness Aware Content-Centric Networking in WSNs

The Content-Centric Networking (CCN) concept is a significant approach of several future Internet research activities. CCN in Wireless Sensor Networks present a promised technique that may ensure data routing based on content. In this paper, we focus on the lifetime of the Content Object exchanged in the network and we explain the idea of its integration in CCN for WSNs to better highlight the relevance of its exploitation. To this end, we implement DFCCN-WSNs `Data Freshness aware Content-Centric Networking in Wireless Sensor Networks' a protocol that implements the data lifetime. Through extensive simulations, we demonstrate that DFCCN-WSNs outperforms traditional CCN in terms of end-to-end delay.
