Spatial Reuse in Wireless Ad-Hoc Networks

Free registration required

Executive Summary

When investigating co-channel spatial reuse, typical studies on ad-hoc networks have adopted static, device-specific transmission/interference ranges regardless of the runtime environment. In this paper, the authors present an analytical framework to investigate co-channel spatial reuse in dense wireless ad-hoc networks based on RF propagation models for some common network topologies. They derive the minimum separation between simultaneous co-channel transmitters while maintaining desirable signal-noise-interference-ratio at receivers. Spatial reuse is characterized by the ratio between co-channel Transmitter (T-T) and Transmit-Receiver (T-R) distances.
