This paper researches and analyzes IEEE 802.15.4 protocol which is widely used in the wireless sensor network. It also discusses the influence on the whole network communication caused by IEEE 802.15.4 CSMA/CA algorithm, i.e. the retransfer mechanism after the collision occurred. After analyzing, evaluating and simulating, it would be discovered that the influence on the system performance which caused by the most important three parameters of CSMA/CA algorithm according to the network status.
