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...
متن کاملMulti-channel Medium Access Control Protocols for Wireless Sensor Networks: A Survey
Extensive researches on Wireless Sensor Networks (WSNs) have been performed and many techniques have been developed for the data link (MAC) layer. Most of them assume single-channel MAC protocols. In the usual dense deployment of the sensor networks, single-channel MAC protocols may be deficient because of radio collisions and limited bandwidth. Hence, using multiple channels can significantly ...

متن کاملReasons for priority-based Medium Access in Wireless Sensor Networks
The trend towards heterogeneous wireless sensor networks and cyber-physical systems results in new challenges for the communications protocols. The co-existence of these networks can result in an unacceptable performance decrease if they interfere with each other or share the same radio channel. Especially, in the latter case, priority-based medium access with Quality of Service (QoS) guarantee...
متن کاملTraffic 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...
