UCSE: User created service engine based on MVC model for IoT service

Service providers and manufacturers released their services and functions by open APIs in the Internet of Things (IoT) service environment. And, user wants to create their own IoT service that satisfies the diverse goals in their daily lives. But IoT service creation is difficult to a non-technical user, because the existing service creation environment is required programmable ability and analytical skill about various service factors. So, we need the IoT service creation environment that is easier and suit to a non-technical user through simple process. Therefore, we propose the user created service model that is able to represent various services. And we show the implementation results of user created service engine through the IoT service creation progress according to the target scenario.
