Addressing Co-Channel Interference with PRK-Based Scheduling for Predictable Link Reliability in Wireless Networked Sensing and Control

Case ID:
13-1147

Technology Description

Wayne State researchers have created a wireless networking method that ensures predictable communication reliability as needed by 5G, Internet of Things, cyber-physical systems, as well as their applications in domains such as industrial automation, smart energy grid, and connected and automated vehicles.

In particular, the method solves the 40+ years old open problem of co-channel interference control through field-deployable approaches. Co-channel interference is when two or more wireless network nodes (e.g., wireless access points, laptops, and smart phones) transmit on the same frequency at the same time. If not controlled well, co-channel interference leads to packet loss, low communication reliability, large and unpredictable communication delay, low and unpredictable communication throughput, and unnecessarily high energy consumption. With WSU technology, network devices coordinate with one another in a purely distributed manner to ensure predictable control of co-channel interference, thus enabling predictable communication reliability, timeliness, throughput, and energy efficiency. This method can be used on any type of wireless communication and in both static and mobile networks. This method can be seamlessly integrated with existing and emerging industry standards such as Zigbee, DSRC, WirelessHART, ISA100.11a, WIA-PA, WiFi, and 5G.
