Abstract:
Wireless Body Area Network (WBAN) is the
cheapest solution using BioMedical Sensors. They monitor
different physiological vital signs of a patient. The output of vital
signs does not accept collision, delay, loss, and a high energy
consumption of BMSs. This paper proposes Energy Efficient and
Delay-Aware Adaptive Slots Allocation Medium Access Control
(EED-MAC) Protocol for WBAN. This Proposed MAC provides
sufficient and dedicated channels to all types of BMSs. The
patient’s data are divided according to the need of a patient.
Moreover, the contentions of BMSs are reduced and does not drop
data by proposing a Reduced Contention Adaptive Slots
Allocation CSMA/CA (RCA-CSMA/CA) scheme. The third
proposed scheme is Reliability-Aware Channel Allocation (RAC),
which allocates channels for emergency-based BMSs using alert
signals without contention. The simulation of the proposed MAC
and other schemes achieve significant improvements against the
state-of-the-art MAC protocols.
