Akıllı Ev Sistemlerinin Yeni Nesil Bulut Tabanlı IoT Teknolojisi

Öz

Günümüzde, büyük ölçekli binaların daha kolay yönetilmesini sağlamak ve tüm sistemlerin daha verimli çalışmasını sağlamak için bina kontrol sistemleri modern yaşamın yaygın bir parçası haline gelmektedir. Bina kontrol sistemlerinde, proses kontrolü için kontrol panelleri, PLC, KNX ve BACnet protokolleri gibi çeşitli sistemler kullanılmaktadır. Bina otomasyonu, binanın ısıtma, havalandırma, klima (HVAC), elektrik, aydınlatma, güvenlik kamera sistemleri, bina içindeki kapılar, asansörler ve kontrol sistemlerinde yer alan daha birçok prosesi içerir. Ancak, tüm bu sistemler tek bir platformdan yönetilemez. Gelişmiş otomasyon sistemlerine olan talep arttıkça, mevcut kontrol sistemleri yetersiz kalmaktadır. Etkili bir otomasyon kontrol sistemi inşa etmek için, tüm bu cihazların farklı alt sistemlerle kolayca iletişim kurması, entegre olması ve bilgi alışverişinde bulunması gerekir. Cihaz yönetiminin tek bir merkezde toplanması ve bu cihazların farklı alt sistemlerle etkileşim içerisinde bir Nesnelerin İnterneti (IoT) ekosistemi oluşturması, çeşitli güvenlik açıklarının ortaya çıkmasına neden olmaktadır. Bu durum, IoT ekosistemini dış tehditlere, özellikle siber saldırılara, karşı önemli ölçüde savunmasız hale getirmektedir. Bu bağlamda, söz konusu sistemlere ilave güvenlik protokollerinin entegre edilmesi ve ekosistemin güvenliğinin sağlanması zorunlu hâle gelmektedir. Bu çalışmada, MQTT protokolüne dayalı bulut tabanlı yeni bir güvenlik protokolü eklenmiş bir akıllı ev otomasyon sisteminin tasarımı gerçekleştirilmiştir. Sistemin çalışabilirliğini test etmek için bir prototip geliştirilmiş ve bu ürün çalışabilirlik ve analiz için sisteme entegre edilmiştir. Sistem ayrıca, tüm platformlarda çalışan bir sistem ve bir mobil uygulama aracılığıyla evi ve çevresini kontrol etmekte ve izlemektedir.

Next Generation Cloud-Based IoT Technology of Smart Home Systems

Öz

Today, building control systems are becoming a common part of modern life to provide easier management of large-scale buildings and to make all systems work more efficiently. In building control systems, various systems such as control panels, PLC, KNX, and BACnet protocols are used for process control. Building automation includes the building's heating, ventilation, air conditioning (HVAC), electricity, lighting, security camera systems, doors inside the building, elevators, and many more processes involved in control systems. However, all these systems cannot be managed from a single platform. As the demand for advanced automation systems increases, existing control systems become insufficient. In order to construct an effective automation control system, all these devices must easily communicate, integrate, and exchange information with different subsystems. The centralization of device management and the interaction of these devices with various subsystems to form an Internet of Things (IoT) ecosystem lead to the emergence of multiple security vulnerabilities. Consequently, the IoT ecosystem becomes highly susceptible to external threats, particularly cyberattacks. In this context, the integration of additional security protocols into these systems is essential to ensure the protection and reliability of the ecosystem. In this study, the design of a cloud-based smart home automation system with adding a novel security protocol has been carried out based on MQTT protocol. A prototype has been developed to test the operability of the system, and this product has been integrated into the system for operability and analysis. The system also controls and monitors the home and its surroundings through a system that works on all platforms and a mobile app.
