Rapid urbanisation, increasing vehicle ownership and inefficient parking operations have intensified search traffic, congestion and underutilisation of parking resources. This paper presents an integrative review of Internet of Things (IoT)-based smart parking systems, with emphasis on architecture, enabling technologies, operational requirements and deployment in resource-constrained environments. A transparent search and thematic-synthesis procedure was applied to 28 sources comprising 24 peer-reviewed publications and four recognised technical standards. Evidence was extracted on sensing and identification, communication, edge-fog-cloud processing, application services, security, performance evaluation and implementation constraints. The synthesis shows that reliable smart parking is not produced by a sensor or mobile application alone; it depends on coordinated responsibilities across six layers: perception and identification, edge and gateway processing, communication, platform and data management, application services, and security and governance. Ultrasonic, magnetic, infrared, inductive and camera-based methods provide different trade-offs in accuracy, coverage, energy demand, privacy and lifecycle cost. Wi-Fi and ZigBee are suited to bound facilities, while LoRaWAN and NB-IoT support dispersed low-power deployments. Edge and fog processing improve responsiveness and continuity, whereas cloud services support historical analysis and multi-site management. The review identifies persistent weaknesses in short-term prototype evaluation, cybersecurity, interoperability, maintenance planning, cost reporting and evidence from African cities. A phased, context-sensitive deployment framework and a multidimensional evaluation set are proposed for campuses, hospitals, commercial facilities and municipal parking environments.
