Virtualization of Wireless Sensor Network with efficient power saving scheme

Wireless Sensor Network (WSN) has gained more importance in current era and given contribution on broad range of commercial applications. These networks consists of small, battery powered sensors communicating with each other to monitor the environment forming a network with ease of deployment where wired infrastructure is too expensive and difficult to deploy. In applications like home automation, health care monitoring multivendor and heterogeneous sensor nodes are deployed. For such applications virtualization in sensor network (VSN) may provide flexibility, ensure security and increase manageability. WSN implies various challenges in design and operations as major fact that sensor nodes run out of energy quickly has been an issue. So for energy consumption, better and improved clustering routing protocols are needed. This Paper surveys novel approach of using virtual sensor architecture and also presents improved clustering algorithm as efficient power saving scheme. Simulation results indicate superior performance of improved clustering algorithm in energy consumption and VSN approach reduces overall cost and complexity.
