Implementation of Optimized OLSR in 5G based VANETs to Improve QoS

Abstract

5G-based Vehicular Ad-Hoc Networks (5G-VANETs) combine the advancements of 5G wireless communication technology with the capabilities of VANETs. These networks leverage the high data rates, low latency, and massive device connectivity provided by 5G to enable efficient and reliable communication among vehicles and infrastructure. Implementing a VANET environment in real-world scenarios poses significant challenges. This paper focuses on improving the Quality of Service (QoS) in 5G-based VANETs through the implementation of an optimized approach to the routing protocol. The chosen routing protocol for this study is Optimized Link State Routing (OLSR). To optimize the protocol, Cuckoo Search Optimization (CSO) and Simulated Annealing (SA) techniques are applied. The simulation is conducted using the ManhattanGrid mobility model, which provides a realistic representation of the vehicular environment. Various test scenarios are created by varying the vehicular density and vehicle speeds. The performance evaluation of the suggested optimized techniques is carried out using three key metrics: Packet Delivery Ratio (PDR), throughput, and End-to-End Delay (E2ED). The results of the simulation demonstrate that the CSO technique outperforms other optimization techniques in terms of enhancing QoS in 5G-based VANETs.
