Mobility of IP based Wireless Sensor Nodes in Sensor-Grid infrastructure

As the world is moving towards the “Internet of Things” [1], Internet Protocol enabled wireless sensor network is becoming an important research area. In order to make it possible and to facilitate transmission of IPv6 packets over low powered networks, 6Lowpan [2,3] has been introduced. Since the IP- WSN application domain is expanded to real-time applications such as health-care [17] and surveillance systems, a fast and seamless handover becomes an important criterion for supporting mobility in 6LoWPAN [21]. In this paper, we have studied mobility characteristics along with design issues under different mobility scenarios. We propose a scheme to manage the mobility of nodes. The 6LoWPAN based wireless sensor network will be integrated with grid computing establishing a Sensor-grid which may also be used widely in various applications.
