The Case for Addressing the Limiting Impact of Interference on Wireless Scheduling

Free registration required

Executive Summary

Co-channel interference is a limiting factor to the predictability and performance of wireless networks, thus interference-oriented scheduling of channel access has become a basic building block of wireless networking. Despite much work in this area, the existing algorithms did not address the limiting impact of interference when optimizing transmission scheduling. Towards understanding the importance of considering the limiting impact of interference, the authors formulate the concept of interference budget, and they propose the scheduling algorithm iOrder that maximizes the schedulability of future channel access when scheduling concurrent transmissions.
