Redundant Transmission Control Algorithm for Information-Centric Vehicular IoT Networks

Vehicular Adhoc Networks (VANETs) enable vehicles to act as mobile nodes that can fetch, share, and disseminate information about vehicle safety, emergency events, warning messages, passenger infotainment. However, the continuous dissemination of from their one-hop neighbor nodes, Road Side Units (RSUs), VANET infrastructures lead performance degradation VANETs in existing host-centric IP-based network. Therefore, Information Centric (ICN) are being explored an alternative architecture for vehicular communication achieve robust content distribution highly mobile, dynamic, error-prone domains. In ICN-based Vehicular-IoT networks, consumer mobility is implicitly supported, but producer may result redundant data transmission caching inefficiency at intermediate nodes. This paper proposes efficient control algorithm based on network coding reduce redundancy accelerate efficiency dissemination. The proposed protocol, called Network Cording Multiple Solutions Scheduling (NCMSS), receiver-driven collaborative scheduling between requesters sources uses a global parameter expectation deadline effectively manage encoded packets selection sources. Experimental results NCMSS protocol demonstrated analyze ICN-vehicular-IoT networks terms caching, retrieval delay, end-to-end application throughput. throughput 22% higher (for 1024 byte data) than solutions whereas delay reduced by 5% comparison with solutions.
