A trust-aware cluster-based communication architecture for vehicular named data networking

Information-centric Networking (ICN) is a new networking paradigm that aims to solve the problem of traditional TCP/IP-based Internet. Content-centric (CCN) and Named Data (NDN), both based on Interest/Data communication paradigm, are two most well-known specialized implementations ICN. In contrast typical networks, NDN enables intrinsic security, which ensures data security rather than channel security. Each response/data packet in transit has signature contents ensure As result, an invalid indicates unauthenticated packet. This ongoing hierarchical authentication verification approach causes significant delay while providing appropriate levels. highly mobile environment with delay-sensitive applications like Vehicular Ad hoc Networks (VANETs), such technique neither viable nor scalable. We present unique Trust-Aware Cluster-based Communication Architecture (TACCA) for this study, improve NDN-driven VANETs (VNDN). It separates route segments into clusters chooses cluster heads their trustworthiness proximity center location. The selected then charge disseminating interest packets prevent broadcast storm problem. Once producer been located, returned requester quickest secure manner possible. Simultaneously, intermediate vehicles decided whether or not verify data's validity subjective perceptions producer's conduct. calculation complexity time reduced. Our idea able maintain vanilla standards lowering produced end-to-end latency by more three times, according simulation data. proposed TACCA suited networks(...)
