Abstract
Content centric network (CCN) is a robust and uncomplicated communication paradigm. It introduces built-in features, such as data authenticity, in-networking caching, mobility, flow balance methods, and multi-cast data delivery. Data packet flooding is a hot research issue due to the broadcast nature of the CCN-based wireless multimedia sensor networks (WMSNs). To mitigate this problem, in this paper, we have proposed a novel protocol, named packet diffusion-limited protocol for CCN-based WMSNs for smart cities. Extensive evaluation of the proposed protocol is performed by using ndnSIM that is based on NS-3 simulator. Simulation results show that proposed protocol not only limits flooding of Data packets as well as speeds up content download time by using a shortest path.
