QoS Issues with Focus on Wireless Body Area Networks

A Review on Telemedicine-Based WBAN Framework for Patient Monitoring

“…In order to achieve maximum throughput, minimum delay, buffer size limitation, removal of redundancy, and maximum network lifetime, QoS is needed. 41 It supports a bit error rate from 10 -10 to 10 -3 , and latency in medical application should be less than the 125 ms, shown in Table 1. A WBAN should support QoS management features to offer better priority services.…”

Quality of Service Routing Algorithm for Cognitive Wireless Sensor Network

“…The delay incurred in re-establishing paths may cause some packet drops, and thus affects the QoS of the network. There are many studies based on QoS provisioning in Wireless Sensor Networks [6]- [8], [13].Both the functional and non functional parameters related to QoS are shown in Figure1. The QoS parameters are affected mainly due to the mobility of the sensor nodes and also with limited energy resources.…”

A Study on Various Issues in Different Layers of WBAN

“…Hanson et al [13] discussed about Body Area Sensing process, application areas, signal processing schema, communication, storage, feedback control, energy harvesting, hierarchical aggregation, topologies and coordination aspects. Ameen et al [14] considered the QoS aspects with internal and external parameters so that the communication metrics will be analyzed and the strength to the network support will be explored. Author analyzed the network protocols under requirement and QoS parameters.…”
