University of Pittsburgh researchers explore enabling lag-free connections in massive IoT devices

Researchers at the University of Pittsburgh's Swanson School of Engineering have proposed a system that would use resources that are currently under utilised in an existing wireless channel in order to create more opportunities for lag-free connections. The system will require no additional hardware or wireless spectrum resources and will minimise traffic backups on networks with several wireless connections. Dubbed ‘EasyPass’, the method would exploit the existing signal-to-noise ratio (SNR) margin, and use it as a dedicated side channel for IoT devices. Testing so far has demonstrated a 90% reduction in data transmission delay in congested IoT networks.
