Virtualization of Wireless Sensor Networks

Abstract

Internet-of-Things (IoT) is considered one of the next technological revolutions. It enables communication among objects of various kinds. Wireless Sensor Networks (WSNs), being the basic elements of IoT, can help users (humans or machines) to interact and react to realworld events. WSN nodes are capable of sensing, communications, and computations; and are getting more powerful. Though various advantages, but one obvious drawback WSNs have is that they are domain-specific and task-oriented, which means they are designed to serve one particular application without the possibility of being reused for another application. This leads us to redundant deployment of WSN infrastructure in a particular are for multiple similar applications. For example, in a military environment the temperature monitoring WSN infrastructure would probably be different from the infrastructure to monitor the enemy movement. Such redundancy increase infrastructure cost. With the philosophy of IoT, in the future, WSN deployment should support multiple applications simultaneously.
