- In this paper, we propose an analytic model to analyze a wireless sensor network (WSN) operating the IEEE 802.15.4 slotted CSMA/CA protocol with ACK mode. Based on the renewal approximation for the data frame transmission process, we first develop an analytic model for a homogeneous WSN where all nodes in the network have the same traffic characteristic. Using our analytical model, we obtain performance metrics such as network throughput, average service time for successful transmissions, the transmission success probability, the frame dropping probability due to transmission failures, and the frame dropping probability due to CCA failures. Through numerical studies and simulations, we validate our analytic model. © 2010 Elsevier GmbH. All rights reserved.
