Abstract
In this paper, we consider an IEEE 802.15.4-based Wireless Body Area Network (WBAN), where different biomedical sensors are distributed on a human body and have to send the measured data to a coordinator node. Focusing on the Slotted Carrier Sense Multiple Access with Collision Avoidance algorithm (Slotted CSMA/CA) defined by the IEEE 802.15.4 norm in the beacon-enabled mode, we propose an enhanced backoff strategy to provide nodes an equitable access to the communication medium. Then we analyze its performance over realistic requirements of the considered sensors using the latest version of Castalia Simulator. The obtained results reveal the efficiency of our proposal as compared to the traditional profile of the norm in terms of reliability, timeliness and throughput.
