MAC Protocol Design for IoT Applications

#IoT #applications #MAC #protocal

In this presentation, we introduce media access control (MAC) protocol design for two IoT applications, i.e., vehicle-to-vehicle (V2V) safety message broadcast in connected vehicles and smart factory in industry IoT. For each considered application, we investigate its unique communication characteristics, design our MAC protocol accordingly, and model and analyze the performance of the proposed design. For the V2V safety message broadcast, we develop a fully distributed MAC that achieves substantially lower delay and collision probability compared to existing distributed MAC designs. For the smart factory application, we develop a centralized MAC that can support a large number of devices with a single communication channel while satisfying stringent delay and collision requirements. Through the two examples, we demonstrate the potential of MAC design innovations in supporting emerging IoT applications.
