WISN: Effective authentication by VCA

As Wireless Sensor Network (WSN) consists of large number of Sensor Nodes (SN) which are dynamic and ad-hoc in nature used to transfer data, where providing security place vital role. So Authentication is an essential requirement in sensor network pursuing security and solved by integrating Wireless Sensor Networks (WSN) with the mobile network and can utilize the combined capabilities of both networks. To address the problem of authentication in WSNs this paper proposes an efficient and secure framework which provide authentication to a roaming sensor node while allowing a sensor node to move across multiple WSNs. The proposed key management technique to provide authentication is by using Virtual Certificate Authority (VCA) which is designed especially for distributed Adhoc network.
