Secure proxy MIPv6-based mobility solution for LPWAN

With the advancement and the wide deployment of the Internet of Things, Low Power Wide Area Network (LPWAN) technologies will respond to applications requiring low power and long range features. In this context, mobility is an additional requirement needed by several applications including supply chain monitoring and health-care supervision. Proxy Mobile IPv6 (PMIPv6) as an extension of Internet Protocol (IP) is used in the LPWAN protocol stack since it provides mobility management. But PMIPv6 does not provide secure access for mobile nodes joining to the network. In this paper, we propose a new mobility solution for LPWAN based on PMIPv6 and we provide a new authentication mechanism to achieve secure access to the network. Thereafter, we evaluate the performance of the proposed solution by simulation using the Network Simulator 3 (NS-3) and by theoretical analysis. Moreover, the security of the proposed authentication mechanism is assessed using an informal security analysis as well as using the AVISPA validation tool. Finally, we compare the performance of our solution with other proposed solutions where we show the improvements made by our solution with respect to several parameters and requirements.
