Techniques are described herein for a mechanism to determine Clear Channel Assessment (CCA) thresholds in the scope of link neighbors in low power and lossy wireless networks. Without adding too much extra traffic, a dynamic, newly designed CCA threshold is unique for each link neighbor and helps to improve the wireless network performance.
