Energy Efficient Service Embedding In IoT over PON

In this paper, we present an energy efficient service embedding framework in Internet of Things (IoT) network using Mixed Integer Linear Programming (MILP). The framework enables an energy efficient smart road paradigm for different simultaneous applications supported by a passive optical network (PON) and wireless communication in the smart city. It optimizes the infrastructure's resources including the access network, IoT, fog and cloud computing. We consider an event-driven paradigm in a Service Oriented Architecture (SOA) in our framework in order to provide service abstraction of basic services which can be composed into complex services and exploited by the upper application layers. The framework results show that it is possible to reduce the power consumption by optimizing the selection of computing nodes and traffic distribution in the network while satisfying the service requirements.
