“…Table 1 summarizes the main articles published in the last four years and their goal and QoS strategy. Among different QoS methods, studies focus mainly on four common strategies: (i) scheduling protocols [15,16]; (ii) data prioritization [15][16][17][18][19][20][21][22]; (iii) routing protocols [22][23][24][25][26][27]; (iv) resource management [16,21]. Studies have examined the use of data prioritization to reduce transmission time.…”

“…On the other hand, scheduling protocols control the time slot assignment for each data transmission and their order based on the amount and type of data. Several studies present QoS strategies for Wireless Body Area Network (WBAN) infrastructures [16,22,[24][25][26][27]29]. A WBAN comprises a private network of connected sensors transmitting data to a master node that relays the information to upper network layers.…”

Background: the increasing adoption of smart and wearable sensors in the healthcare domain empowers the development of cutting-edge medical applications. Smart hospitals can employ sensors and applications for critical decision-making based on real-time monitoring of patients and equipment. In this context, quality of service (QoS) is essential to ensure the reliability of application data. Methods: we developed a QoS-aware sensor middleware for healthcare 4.0 that orchestrates data from several sensors in a hybrid operating room. We deployed depth imaging sensors and real-time location tags to monitor surgeries in real-time, providing data to medical applications. Results: an experimental evaluation in an actual hybrid operating room demonstrates that the solution can reduce the jitter of sensor samples up to 90.3%. Conclusions: the main contribution of this article relies on the QoS Service Elasticity strategy that aims to provide QoS for applications. The development and installation were demonstrated to be complex, but possible to achieve.

Our world has been changed a lot over the past few years. Only a few decades back and you will see that communication among people was not an easy task at all. Thanks to the advancement in technologies especially the networking techniques that have made the lives of the people so comfortable. Now due to these computer networks, communication with your family, friends, and colleagues is so easy all across the globe. This communication is not only limited to the entertainment or information anymore. Wireless Body Area Networks has made it possible for the doctors to keep in touch with their patients and check their health conditions while staying miles away from them physically. This application of Computer Networks is impacting so many lives in the world in a very positive way. This technology is helping people in getting better health services without taking the time to go to their doctor or changing their daily routine. This application has so many benefits but at the same time it is also facing challenges and secure transfer of the data is one of the challenges and researchers are working to make sure to keep data of the patients secure.

In wireless networks, a change in network state is unpredictable because of the movement of network nodes, which is not conducive to the stability of the network and poses an especially serious challenge to network routing technology. To adapt to the flexibility of business, consider the impact of environmental changes on the bottom layer of a network, and improve the utilization of network resources, this paper proposes a multipath routing decision strategy restricted by multiple QoS attributes based on an intuitionistic fuzzy set of entropy weights. Cross-layer technology is applied to minimally meet the QoS needs based on multipath routing to discover and maintain multiple transmission paths. Moreover, intuitionistic fuzzy set theory is utilized to reflect the performance indexes of these multiple paths through fuzzy normalization to create a multiparameter multipath routing decision matrix. The weight of each parameter is objectively computed according to information entropy theory. The performance ranking of the multiple paths is determined with the TOPSIS method. As reflected by the results, the TOPSIS decision method based on an intuitionistic fuzzy set of entropy weights effectively solves the optimization problem for multiple paths in mobile ad hoc networks restricted by multiple parameters, and the resulting network is suitable for sensitive network applications involving multiple businesses in mobile environments. According to the simulation results, the proposed routing scheme reduces average network delay by 17% and routing overhead by 21% when compared to the current routing protocols.
