摘要：This paper introduces a performance model of a recently proposed backoff technique named Non-overlapping binary exponential backoff algorithm over IEEE 802.15.4, which is designed for LR-WPAN. To reduce the collision rate in highly populated wireless networks, non-overlapping binary exponential backoff tries to evenly distribute the random backoff delay by distinguishing the new range of backoff delays. For the performance measurement of non-overlapping binary exponential backoff algorithm, obtained results are compared with the traditional model of IEEE 802.15.4. Our numerical analyses show that non-overlapping binary exponential backoff improves the throughput and transmission delay comparing to the traditional BEB
