The authors introduce a linear measurement-based method for interference estimation in wireless mesh networks. The approach is based on measuring the channel occupancy and requires only O(n) measurements for a network with n nodes, thus making it suitable for large network deployments. They show, how they utilize the carrier sensing mechanism of commodity IEEE 802.11 hardware to measure the channel occupancy. Based on the measurements, they develop the Channel Occupancy Interference Model (COIM). The model is validated in the DES-Testbed, a wireless mesh network with 128 multi-radio network nodes at the Freie Universit?t Berlin.
