Mobility management in IP based Wireless Sensor Network using TinyOS

Mobility management is one of the most important research issues in 6LoWPAN which is a standardized IP based Wireless Sensor Networks (IP-WSN) protocol. Since the IP-WSN application domain is expanded to real-time applications such as health-care and surveillance systems, a fast and seamless handover becomes an important criterion for supporting mobility in 6LoWPAN. In this paper, we have studied mobility characteristics along with design issues and different mobility scenarios. Also, two approaches are incorporated for mobility management namely timer driven and message driven approaches. Both of these are implemented using TinyOS.
