System Design in Sensor Network Virtualization for SHAAL

Wireless Sensor Network (WSN) has led to a new paradigm of Internet of Things (IoT). WSNs are usually deployed for particular application. However, the future of WSNs in Smart Home and Ambient Assisted Living (SHAAL) lies in the aggregation and allocation of resources serving diverse applications. Virtualization of a sensor network is an emerging concept that enables aggregation of multiple independent heterogeneous networks. Virtualization poses overhead challenges like more processing and power consumption. In this paper efforts have been put forward by proposing a secure and energy aware middleware framework whose most part resides on the gateway of WSN and provides sensor virtualization as well as network virtualization for SHAAL.
