SMART VEHICLE TRACKING SYSTEMS:

Vehicle tracking systems are increasingly used to locate vehicles, monitor movement, improve fleet operations, and supportsafety. This paper presents a focused survey of three related approaches: GPS-Based Vehicle Tracking System, IoT-BasedReal-Time Vehicle Tracking System, and Smart Vehicle Tracking Using GPS, IoT, and Mobile Applications. The first approachemphasizes satellite-based location estimation; the second connects vehicle sensors and tracking devices to communicationnetworks and cloud services; and the third combines location, connected devices, and a mobile interface for convenient accessto live or recent vehicle information. The survey compares system architecture, data flow, benefits, limitations, security concerns,and practical use cases. Across the approaches, tracking accuracy and usefulness depend on satellite visibility, connectivity,device quality, power supply, and software design. Connected tracking also raises privacy and cybersecurity considerations,including access control, consent, secure data transmission, and limited retention of location history. This paper is a focusedconceptual survey rather than an experimental evaluation or a new systematic literature review. It concludes that an integratedGPS–IoT–mobile design can provide a practical tracking experience when designed with reliability, privacy, and responsible usein mind.
