Effective Carrier Sensing in CSMA Networks under Cumulative Interference

—This paper proposes and investigates the concept of a safe carrier-sensing range that guarantees interference-safe (also termed hidden-node-free) transmissions in CSMA networks under the cumulative interference model. Compared with the safe carrier-sensing range under the commonly assumed but less realistic pairwise interference model, we show that the safe carrier-sensing range required under the cumulative interference model is larger by a constant multiplicative factor. For example,
