In this paper, an analytical model for the beacon-enabled slotted CSMA-CA mechanism of IEEE 802.15.4 wireless sensor network is designed. The current mechanism of IEEE 802.15.4 CSMA-CA is extended to include the retransmission limit of the nodes with packet collision probability. A three-dimensional discrete time Markov chain model for the uplink traffic of wireless sensor network is designed to analyze the energy consumption and throughput of the nodes under unsaturated traffic conditions. The energy consumption and throughput are analyzed for different node numbers and data rates to estimate the possible number of nodes for the better performance in terms of throughput.
