Implementing dynamic address changes in ContikiOS

To secure the Internet of Things (IoT) running on IPv6 over Low-Powered Wireless Personal Area Networks (6LoWPAN) by implementing a Moving Target IPv6 Defense (MT6D), there must first be a method developed to dynamically change IPv6 addresses over this resource constrained wireless network. We will discuss how we implemented this dynamic address change and how in doing so, we also had to change the Rime and MAC address thus implementing a moving target defense at Layers 2 and 3 of the OSI Model. We conducted our experiments in Contiki OS and utilized the Routing over Low-powered and Lossy Networks (RPL) protocol to perform the address changes between a node and its parent border router.
