An Adaptive TDMA Approach for Improving Reliability and Performance in WBAN under Heterogeneous Traffic and Interference

Abstract

Medium Access Control (MAC) based on Time Division Multiple Access (TDMA) sublayer approaches have been proposed to improve Wireless Body Area Networks (WBAN) reliability and efficiency. These approaches inadequately deal with device heterogeneity and the message traffic dynamics in WBANs. We propose an adaptive policy TDMA-based MAC protocol. To improve policy communication between devices, each one receive time slots for transmission, considering their band-width and communication channel interference. Our approach simulations results show significant reliability and performance compared to IEEE 802.15.4, IEEE 802.15.6, and DSBS (Dynamic Scheduling Based on Sleeping Slots) protocols. The protocol decreased message loss while maintaining low power consumption and low latency in experiment simulation scenarios.
