In this paper, we study the maximum throughput of IEEE 802.15.4 enabled wireless sensor networks (WSNs). In general, deploying more sensor nodes would increase the throughput, but if excessive sensor nodes were involved to report data, the throughput might decrease due to packet collisions. In this paper, we analyze the CSMA/CA performance of the IEEE 802.15.4 enabled WSNs, and develop an analytical throughput model between the maximum throughput and the optimal number of deployed sensor nodes. Extensive simulations are conducted to verify our analytical throughput model.
