Middleware framework for network virtualization in SHAAL

Wireless Sensor Network (WSN) has led to a new paradigm of Internet of Things (IoT). WSNs are usually deployed for a particular application. However, the demand of WSNs in Smart Home and Ambient Assisted Living (SHAAL) is the accumulation and allocation of multiple resources providing diverse services and applications. Virtualization of a sensor network is an emerging technique that permits aggregation of several independent heterogeneous sensor networks. The technique of virtualization poses overhead challenges like more processing and power consumption. In this paper efforts have been put forward by proposing an energy aware middleware framework that resides on the sensor nodes to achieve network virtualization for SHAAL.
