Master Thesis OfferReal-Time Communication in theIndustrial Internet of Things (IIoT)

MotivationIndustrial Internet of Things (IIoT) is an emerging paradigm that targets to realize the Indus-try 4.0 revolution. Low-power industrial wireless sensor and actuator networks (IWSAN) playa crucial role to support IIoT as depicted in Fig. 1. However, the real time requirements ofindustrial applications pose challenges of high reliability, timeliness, and energy efficiency.In order to provide real time guarantee, the Medium Access Control (MAC), as shown inFig. 2, can be exploited to achieve the required real time performance.In this Maser thesis,we explore MAC layer in determining an optimal scheduling scheme that helps sensor andactuators to communicate while guaranteeing, reliability, bounded end-to-end delay, energyefficiency and meet the packet delivery deadlines.
