A Review on Virtualization in Wireless Sensor Network

Wireless Sensor Network (WSNs) has played a vital role in current era on broad range of commercial applications such as in home automation, health-care and automation industry. In such kind of application multi-vendor and homogeneous sensor nodes are deployed. By allowing heterogeneous wireless sensor networks to coexist on a shared physical substrate, virtualization in sensor network it may provide flexibility, promote diversity, ensure security and increase manageability. This paper surveys the novel approach of using the virtual sensor architecture and give emphasis’s on the opportunities and the challenges in the research field.
