Hybrid power control and contention window adaptation for channel congestion problem in internet of vehicles network

Abstract

Technology such as vehicular ad hoc networks can be used to enhance the convenience and safety of passenger and drivers. The vehicular ad hoc networks safety applications suffer from performance degradation due to channel congestion in high-density situations. In order to improve vehicular ad hoc networks reliability, performance, and safety, wireless channel congestion should be examined. Features of vehicular networks such as high transmission frequency, fast topology change, high mobility, high disconnection make the congestion control is a challenging task. In this paper, a new congestion control approach is proposed based on the concept of hybrid power control and contention window to ensure a reliable and safe communications architecture within the internet of vehicles network. The proposed approach performance is investigated using an urban scenario. Simulation results show that the network performance has been enhanced by using the hybrid developed strategy in terms of received messages, delay time, messages loss, data collision and congestion ratio.

“…They developed a new hybrid game transmission rate and power channel congestion control approach on IoV networks, where the nodes play as greedy opponents demanding high information rates with the maximum power level. A new congestion control approach is proposed which is based on the concept of hybrid power control and contention window to ensure a reliable and safe communications architecture in IoV [ 87 ].

A systematic review of congestion control in internet of vehicles and vehicular ad hoc networks: Techniques, challenges, and open issues

“…These factors cause to transport of massive quantities of incorrect data, which is a complete waste of bandwidth and storage, whereby users face limitations in receiving network benefits. To improve quality of service (QoS) and reduce server costs, VANETs and IoV need an effective resource management solution 18–38 . In this direction and the field of congestion control in VANETs and IoV networks, researchers have improved the main challenges of resource management, which are bandwidth and storage, by using factors such as a better average PDR 18,26,35 , better accuracy 21,38 , increasing transmission performance 22,28,31 , improving arrival time 23,36 , enhancing throughput 25,35 , decreasing the E2E delay 23,27 , and minimizing packet loss 31 .…”

According to the articles that we have considered in the resource management section to check their innovation in the direction of congestion control in VANETs and IoV networks, it can be said that the common innovation between them is providing approaches such as transfer messages over channel approaches 19,23,32 and channel congestion control system 18,29,32 in single link and multiple links, controlling transmission power and hybrid traffic control strategy that has greatly helped to reduce congestion in VANET and IoV networks. But there are still limitations such as less flexibility 21,29 and a lack of investigation of network cost 31,35 in this category, which needs more research.…”
