14 Specialist IoT Challenges Push Teams to the Limit at IIID

At the Iran International Innovation District (IIID), the second day of the 2025 Technology Olympiad’s Internet of Things (IoT) competition put 13 finalist teams through 14 advanced challenges to evaluate their technical capabilities in high-volume data transfer, jammer detection, and maintaining control of smart industrial and agricultural networks under interference conditions.

Shiva Mohammadi, executive secretary of the IoT competition, said today’s challenges were designed with a high difficulty level and targeted three domains: seven in industry and agriculture, four in IoT cybersecurity, and three in hardware (“things”).

One of the toughest tasks involved data transmission over GPRS with extremely limited bandwidth, requiring teams to send high-volume sensor output (100 samples per second) reliably — simulating conditions found in large-scale industrial environments.

Another key challenge focused on detecting and handling jammers: in smart farms or factories, anonymous code can enter networks and disrupt sensor transmissions. Participants had to perform precise scans on provided Lora networks to identify jammers and then maintain data flow and operational control despite interference.

Teams were evaluated on solutions resistant to communication disruptions. From the original 116 teams in the preliminary round, 13 have reached the finals and are now competing for top positions.
