Abstract: Several influencing factors on the link quality of WSN were discussed and, based on the protocol in the standard IEEE802.15.4, the formats of MAC data frame and the mechanism of data transmission were amended. Then, a method was designed to measure the link quality of WSN so as to avoid the influence of different frame lengths and enable the wireless sensor nodes to acquire data better from communications link. Measurement was carried out according to the standard IEEE 802.15.4 and the amended method separately, and measured data were analyzed, compared and evaluated.
