Energy-aware services composition for Internet of Things

Internet of Things (IoT) are going to change our daily live in the near future. As IoT services prevail, many edge server, gateways, sensors and actuators etc. will be widely available in cities and smart spaces. Thus, how do we exploit these resources to provide rich and green services to users has become a very critical issue. In the past, researchers have developed QoS-based service composition schemes for IoT. However, they fail to consider energy efficiency in service composition. This paper extended previous QoS-based scheme to consider power consumption when linking various objects in the IoT environment based on users' demand. Simulation results show that our algorithm performs efficiently regarding computation complexity and energy efficiency in comparison with existing QoS-based algorithms.
