An Approach For Coap Based Notification Service In Iot Environment

The demand on notification services has been greatly increased in the IoT(Internet of things) environment. For supporting a large number of users with limited resources, the development of effective transmission technology on notification service is inevitable. In this paper, we propose an efficient scheme on enhancing the performance of notification system. The proposed approach capitalizes the notion of the feedback concept to maximize the service utilization by preventing the system from delivering unnecessary notification. The simulation result shows that the service utilization is improved reducing wasted cost and the average transmission rate for notification data is increased compared to the existing scheme.
