Energy-Efficient Location and Activity-Aware On-Demand Mobile Distributed Sensing Platform for Sensing as a Service in IoT Clouds
Recently smartphones are in widespread use and they have large storage space and processing power. Thus, the smartphone-based networks with cloud server can be used as a cost-efficient sensing platform with high capable of processing complex, cooperative tasks just in time. However, low level implementation of cloud-based mobile phone applications needs a lot of human efforts, and has a considerable gap with high-level requirement given by application developers. To fill the gap, we propose a support middleware to execute cloud-based mobile sensing applications. Since we have proposed in our previous work, a language to describe high-level specification of cooperative applications on WSN, we extend the concept to manage and control multiple smartphones that participate in the system. We have shown some example descriptions of high-level specifications and have implemented the prototype system to confirm its usefulness.
