Mobility in the Industrial Internet of Things: a performance analysis

The Industrial Internet of Things (IIoT) is an evolution of the traditional Internet of Things (IoT) to include industrial applications with stringent requirements, in terms of reliability and timeliness. To promote the IIoT, the Internet Engineering Task Force (IETF) has defined the 6TiSCH architecture that allows to integrate IoT devices into existing IPv6 networks ensuring the stringent reliability and timeliness requirements of industrial applications. So far, 6TiSCH has been used with static nodes and many solutions for 6TiSCH networks have been developed under this (implicit) assumption. However, node mobility may be an opportunity in industrial settings, as many industrial things may be mobile (e.g., mobile robots). In this thesis, we consider and evaluate an architecture for supporting mobility in 6TiSCH networks. Specifically, we develop MobileTiSCH, a module for the OMNeT++ simulation tool implementing the considered architecture, and use it to evaluate the performance of the above-mentioned architecture depending on various parameters, such as number of border routers, number of mobile nodes, resource allocation, mobility pattern, etc
