Tracking and Controlling High-Speed Vehicles Via CQI in LTE-A Systems

Abstract

One of the most serious problems facing the community around the world is car accidents. These accidents occur mainly due to the high-speed of vehicles. Thus, the paper aims to capture, track, and control high-speed vehicles using LTE-A mobile networks to avoid high-speed situations as well as decrease the number of accidents. The paper assumes that all vehicle drivers are now days carrying their mobiles that can be considered as mobile network user equipment (UE). This paper presents an innovative tracking and controlling high-speed vehicles in the LTE-A system that taking the advantages of Channel Quality Indicator (CQI) value mapped to the UE speed. The method can be accomplished by uploading the CQI index to the base station (BS), at the uplink, then the evolved node base station (eNB) sends an extra warning message at the downlink to initiate the radio frequency identifier (RFID) component fixed on the vehicle. The proposed scheme design assumes that the LTE networks have the all traffic speed for the covered area and to be activated when the speed is beyond the maximum speed. In that case, the RFID is activated and an alarm is switched on. Under now response, the RFID will activate the vehicle's traction control (TC), Engine Control Unit (ECU) and automatic brake system (ABS) to decrease the speed gradually. The proposed scheme was simulated using the system level-simulator (SLS) and the performance is depicted. The evaluations show that the CQI values are decreased meaningfully to 2 when the UE movement in the high-way increases to 150 km/h. Consequently, with the obtainability of CQI values at the LTE-A system, an immediate activity is completed to control the vehicle speed and warn the driver.

Artificial-Intelligence-Enhanced Beamforming forPower-Efficient User Targeting in 5G Networks using Reinforcement Learning

“…The result of each model concludes that both transmission methods are reliable for merging 5G cellular systems. In [13], the authors proposed an integrated system utilizes the 5G wireless cellular integrated with satellite communication systems by taming many downlink channels of the satellite link to manage the new 6G system. With the terrestrial's satellite, the satellite receivers will be directed to the LEO-system are communicated to the 5G systems or base stations.…”

The Application of LoRa Module and Smart Card for A Large-Scale Area Attendance Monitoring System

“…From the test results, it is found that in the room the best RSSI value is when the sending LoRa is placed on the 6th floor, this happens because the receiving LoRa placement is II. 4 Calculates the waiting time between sending LoRa and receiving LoRa. 5…”

“…The Internet of Things (IoT) plays a very important role in various sectors such as education, agriculture, plantations, and smart cities [1], [2], [3], [4], [5]. In the plantation sector, IoT can be used to send the presence status of field workers working for a company.…”
