A Review of Energy-efficient QoS-aware Composition in the Internet of Things

In the Internet of Things, the services provided by the objects which are related, create environments. Those environments are broadcasted as services via the web. It is reasonable to deduce that those environments authorize things to interact with each other and makes the IoT services feasible. Gadgets and tools that use the Internet of Things (IOT) have increased significantly. These tools have similar operating logic, but they have different performance in terms of quality of service (QOS). These services can be configured to facilitate value-added services. While the spatial-temporal limitations of IoT services need to be met more, energy consumption of IoT nodes should be mostly balanced. Consequently, an increase in network lifetime will be achieved. This paper reviews and evaluates the fundamental concepts of IoT Service Composition mechanisms and indicates how well they satisfy the scalability requirements of IoT systems. Subsequently, it investigates what QoS is and how it can be enhanced.
