A Content Dissemination Technique Based on Priority to Improve Quality of Service of Vehicular Ad Hoc Networks

Due to the ability of Vehicular Ad Hoc Networks (VANETs) improve mobility and create innovative services, they have received increasing attention from both industry academia fields. Named Data Networking (NDN) is a network service that has been developed for Internet’s host-based packet delivery model. In VANETs, NDN used as an emerging architecture improving quality (QoS) networks connected cloud mobile Internet Things (IoT). We can achieve this improvement using efficient content dissemination forwarding technique depends on name-based routing, in-network caching, interest-based retrieval. The large amount data processed by several IoT sensors or nodes VANETs makes prioritizing mechanism crucial, especially when many end-users need common simultaneously. Therefore, in paper, we propose based priority boosting requirements NDN-based VANETs. approach prioritizes flow traffic into four classes: urgent, emergency, least, average novel constrained location deadline method, called New method employing Deadline Distance Size (NDDS). highest assigned with emergency class, then average, least class. To evaluate proposed technique, numerical simulation experiment conducted CloudSim toolkit. results demonstrate minimum processing time, compared flow, which significantly enhance QoS protocol-based networks.
