Design of an adaptive medium access control protocol for wireless body area networks with heterogeneous sensors

Adaptive Medium Access Control for Heterogeneous Wireless Sensor Networks

In this PhD thesis, we consider heterogeneous Wireless Sensor Networks (WSNs) in which several sensing devices with different characteristics coexist. In contrast to a homogeneous sensor network, in heterogeneous networks different sensors may sense different physical phenomena generating traffic that have different characteristics such as monitoring temperature, pressure, and humidity. Moreove...

An Adaptive Congestion Alleviating Protocol for Healthcare Applications in Wireless Body Sensor Networks: Learning Automata Approach

Wireless Body Sensor Networks (WBSNs) involve a convergence of biosensors, wireless communication and networks technologies. WBSN enables real-time healthcare services to users. Wireless sensors can be used to monitor patients’ physical conditions and transfer real time vital signs to the emergency center or individual doctors. Wireless networks are subject to more packet loss and congestion. T...

Traffic Priority-Aware Adaptive Slot Allocation for Medium Access Control Protocol in Wireless Body Area Network

Biomedical sensors (BMSs) monitor the heterogeneous vital signs of patients. They have diverse Quality of Service (QoS) requirements including reduced collision, delay, loss, and energy consumption in the transmission of data, which are non-constrained, delay-constrained, reliability-constrained, and critical. In this context, this paper proposes a traffic priority-aware adaptive slot allocatio...

Wireless Body Area Networks Medium Access Control ( MAC ) : IEEE 802

With recent advances in wireless networking, Wireless Body Area Networks (WBANs) became practically feasible. Body Area Networks are defined by the IEEE 802.15.6 standard. However, IEEE 802.15.4 MAC can also be used for WBANs as it is cheap and simple. This paper presents a study about the standards IEEE 802.15.4 and IEEE 802.15.6. In this paper, both IEEE 802.15.4 and IEEE 802.15.6 are explain...
