摘要: Low-powered and light-weight sensor nodes will be deployed for e-health services in wireless body area networks (WBANs). Recently, the Institute of Electrical Electronic Engineering (IEEE) introduced a new standard, IEEE 802.15.6 communications. The goal this standard is to specify several physical layers (PHY) medium access control (MAC) layer protocols variety applications with various QoS requirements. In paper, we evaluate performance WBAN MAC protocol terms throughput, power consumption, energy efficiency under unsaturated conditions. We develop discrete-time Markov chain based analytical model CSMA/CA during contention phases. To verify numerical results obtained from model, performed simulations compared results.
