  • Description of Invention

    Vehicular Ad Hoc Networks, better known as VANETs, is an ad hoc network where the vehicle acts as a node. VANET has the characteristics of a changing topology due to mobility and high speed. Generally, there are three types of routing protocol categories: proactive, reactive, and hybrid. These routing protocols may require performance validation in which the suitable protocol would be identified. Hence, the proactive routing protocol was selected as the main object of testing as it has a routing table mechanism that is likely to be improved according to VANET characteristics. Generally, vehicles may receive information to identify traffic congestion or accidents from neighbouring vehicles or the environment. In such a crucial scenario, the topology of a network frequently changes as nodes move at different speeds continuously, leading to certain significant problems that need to be adequately addressed to enable VANET to be reliable. Rapid topology change and frequent disconnection contribute to the emergence of an efficient routing protocol for vehicle routing data, particularly vehicle to vehicle (V2V) communication. The key to an effective routing protocol is necessary because conventional VANET routing protocols are not efficient across all traffic scenarios. The project comprises a testbed developed utilizing a Raspberry Pi 4 as the primary microcontroller, as well as a Cytron Maker Uno with additional modules. The testbed incorporates three routing protocols that have been modified to be observed in two different traffic type scenarios. In order to show the conceptual idea of V2V communication, these scenarios were measured in terms of the Quality of Service (QoS) index measurement based on throughput, delay, jitter and packet loss. Additionally, the recent push of National Automotive Policy (NAP) 2020 aims to transform the Malaysia Automotive Industry towards Connected Mobility Ecosystem (CME) by 2030. The policy establishment ensures that Malaysia would support developing regulations, especially in automated, autonomous, and connected vehicles. As such, this project could considerably be part of the applicability of V2V technology moving closer to reality.
