Researchers at the University of Pittsburgh’s Swanson School of Engineering have proposed a system that will use currently underutilised resources in an existing wireless channel to create extra opportunities for lag-free connections.
According to the University, the process, which does not require any additional hardware or wireless spectrum resources, could alleviate traffic backups on networks with many wireless connections, such as those found in smart warehouses and automated factories.
The researchers announced their findings at the Association for Computing Machinery’s 2019 International Conference on Emerging Networking Experiments and Technologies, one of the best research conferences in networking techniques. The paper, titled”EasyPass: Combating IoT Delay with Multiple Access Wireless Side Channels,” (DOI: 10.1145/3359989.3365421), was named Best Paper at the Conference. It was authored by Haoyang Lu, PhD, Ruirong Chen, and Wei Gao, PhD.
Lab tests have demonstrated a 90 percent reduction in data transmission delay in congested IoT networks, with a throughput up to 2.5 Mbps over a narrowband wireless link that can be accessed by more than 100 IoT devices at once.
