In this chapter, we investigate the message delivery performance of IQRF networks for broadcast messages using flooding routing with Time Division Multiple Access (TDMA) media access. IQRF networks benefit from redundant paths, which enhance their robustness and reliability. However, these networks do not display all connections between nodes after setup and discovery. To address this, we introduced network mapping methods that utilize the adjacency matrix to reveal all connections within the network. Using this approach, we tested how varying the number of redundant connections affects packet delivery ratios under different failure conditions. Our findings provide valuable insights into optimizing network robustness and improving message delivery reliability in IQRF networks, highlighting the critical role of redundancy in maintaining effective communication.
