  Abstract

IEEE 802.15.4 uses Slotted CSMA/CA for a chanel access by MAC layer. Slotted CSMA/CA decides a range of Backoff Time to use BE(Backoff Exponent). A performance is good a small Backoff Time by less device more than many device. In case of few device, IEEE 802.15.4 sets BLE field for reduce a energy consumption. But in case of many device isn't special set. There are many devices that want to join into PAN in U-Healthcare environment. In this paper we proposed chanel access using IPM field in IEEE 802.15.4 for improved performance. IPM Field to 1 by setting the BE value macMaxBE Device to transmit data by reducing the conflict between the yield increases to be saturated throughout the simulation results were confirmed.
