Mobility Management for Wireless Sensor Networks A State-of-the-Art

The advent of the Internet of Things where billions of devices are able to exchange their data to give a better control to users on their environment has led to the expansion of Wireless Sensor Networks (WSN). To address the specificities of WSN, standards on networking protocols for low power sensors such as 6LoWPAN have been developed. While 6LoWPAN is well suited to fixed-sensor WSN, it must be extended to better address mobile sensors. However, so far little effort has been devoted to the handling of mobile sensor node peculiarities. In this article, generic mobility scenarios are highlighted, existing mobility solutions based in Mobile IPv6 are reviewed and remaining challenges to handle mobile sensors properly are identified.
