These technologies in communications domain integrated into conventional medical system and assists as a capable methodology to boost the efficiency of health-care. Wireless body area networks contain dissimilar biosensors are fitted in a patient for analyzing the condition of health continuously. The collected parameters of signals are initially given at a gateway for the accretion of data and then furthered to out-of- the-way medical centers. Patient’s smart devices which has internet connectivity act as the gateways in internet of things-based WBANs, each among them generally stands for single patient. A huge volume of medical data congestion will be occurred during the widespread use of IoT-based WBANs, which is leading to an imperative prerequisite with high utilization based efficiency system for radio resource management. Henceforth, this survey examines methodically the management of transmissions of wireless body area network (WBAN) for internet of things-based a network is sculpted as a multi-server priority queueing system with multi-class delay-constrained with. Based on the result of queueing data packet, a mechanism for the arrangement of data packet transmissions for medical purposes with delay constraints is deliberated. Keywords— IoT-based healthcare, priority awareness, truthful mechanism, WBAN transmission scheduling 1. Introduction With the improvements in technology which includes sensor technology, such as MEMS-micro- electro-mechanical systems, wireless based networking system, and low power consumption based sensors, there is a rapid improvement of wireless communication and low-strength multi-function sensors. The improvement on such technologies contributes to the development of such equipment portable, condensed and less-powered, offering a fundamental for the WBANs [1]. Wearable biosensor are one of the discipline of wireless body area networks or devices placed in a human body, which has emphasis on the dimension of such gadgets and less power wireless conversation among them. These nodes which have the sensor are capable of assembling physiological alerts of interest, which includes ECG data, blood hypertension and hypotension level, blood sugar level, temperature, voluntary and involuntary movement or activity indicators, and peripheral evidence of the human body, and also are able to process and broadcast of the acquired data. Wireless body area network (WBAN) is one crucial module of electronic-health recording. Generally, a wireless body area network is arranged on a patient, and customarily contains of a gateway and some of medical MEMS based sensors. These MEMS sensors are continuously used for tracking several sorts of physiological indicators. The statistics data handshaking between those medical MEMS sensors and the gateway is found out by using intra- wireless body area network communications, which has been underlined in IEEE stds. 802.15.4 [4] and 802.15.6 [5]. Every gateway gathers biomedical signals from medical sensors which have been distributed or placed in the body, and then onwards those Content from this work may be used under the terms of the Creative Commons Attribution 3.0 licence.

Although many researches had been carried out on growing WBAN-based health monitoring systems [6]–[7], maximum of them are restrained their attentions on intra-WBAN network communications, even rare studies regarding WBAN communications has been done [8]. Indeed, it is vital to model proficient transmission approach for scheduling beyond-WBAN communications for the following aspects i) the transmissions of data in beyond- wireless body area network would be explosively waned with an extensive distribution of wireless body area network in the next future; and ii) outdated technologies, like cellular networks and WiFi, can barely encounter the needs for pervasive electronic-health services because of their limitations in spectrum resource [9]. In addition, for transmissions of medical data, the most important things to be considered is the quality of service (QoS) being provided for the data transmission. This need a promising indicator that have to report a priority of higher order over non-emergent ones [10]; and ii) transfer of consistent medical data consisting of physical parameters should be planned by conjointly taking the information and delay time [11]. In electronic-health systems, based on the application-specific criticality levels the packets of data are generally categorized into numerous classes. For instance, the data acquired from the electrocardiogram is given priority more significant than body temperature, though both the parameters belonging nonemergency. Nevertheless, excessive delays occur in any generous of information related to medical data may also lower the timeliness of data transmission or distress the accuracy of disease monitoring and diagnosis. Along with it, the implementation of priority-aware beyond wireless body area networks transmission scheduling depend on the medical packets, which is needed to be reported by concomitant gateways. Nevertheless, unlike simple-architecture sensors, wireless body area networks-gateways are meant to be smart devices high intellectual data processing capability, So that they may behave tactically and inconsiderately [11]–[12]. Perceptibly, in fine structured electronic- health architecture, such deceptive behaviors should be banned. If not, the medical-grade quality of services can certainly not be convinced because of the imprecisely stated priority information, which leads to stern concerns in healthcare system. Furthermore, in order to expedite the application of the system, the complete performance of transmissions data of all medical packets should be maximized. Technically mentioning, the designing this sort of beyond- wireless body area network mechanism for transmission scheduling with all above-mentioned capabilities is quite challenging due to attain medical-grade quality of services, beyond-wireless body area network data transmissions is to be modeled consistent with a delay-based precedence order, in the meantime defensive emergent information deliveries. It necessitates the attention of priorities in dynamic scheme in the data scheduling method. a) Since the gateways for data transformation are coherent and selfish, the modeled scheduling mechanism need to be capable of induce gateways to candidly state the real classes in their medical data packets. b) With dynamic natures of beyond- wireless body area network data transmissions and considered from communication gateways, it is tough to effectively control the scheduling unit in higher order. In the preceding works [13], [14], design approach was adopted firstly in beyond- wireless body area network scheduling the transmission. Nevertheless, there exist some sturdy boundaries in mechanisms contrived by [13] and [14]: i) both the systems laboring a class-based prioritized scheduling g, which may tremendously leads a huge delays in data transmission for certain medical data packets; ii) the time of transmission of various data packets in beyond-WBANs was considered to be both homogeneous in traits or exponentially placed, which are indeed not practical; and iii) none of them aimed to wane the network health, hence the performance of overall beyond- Wireless body area network transmission scheduling can be far from optimal. 2 IWCASME 2020 IOP Publishing IOP Conf.

  • What About Near Field Communication Technology? an Overview with Possible Future Telemedicine Applications
    What about Near Field Communication technology? An overview with possible future telemedicine applications. Enrico M. Staderini Norwegian Centre for Telemedicine, Tromsø, Norway Correspondence: Nasjonalt Senter for Telemedisin, Postboks 35, N-9038 Tromsø, Norway (Fax: +47 7775 4098; Email: [email protected]) Summary Near Field Communication (NFC), jointly developed by giant players in the consumer elec- tronics arena such as Philips and Sony, is the last in a series of ever evolving wireless network- ing technologies for data transfer. The impacts and the potential uses of this technology (ECMA-340 standard) in the medical device field, and telemedicine as well, are analyzed and compared with existing wireless technologies for data and signal transfer. The intrinsically very short range of NFC is all but a limiting factor indeed. Having the communicating devices to be placed intentionally close to communicate, an higher level of security is obtained: a must for medical privacy sensible data exchange. Furthermore, NFC data rate can go as fast as a few hundreds of thousands of bits per second so to provide a channel wide enough for real time biomedical signal transmission. The extremely low power required for NFC operation, which reaches zero on the target in the passive communication mode, is an extra bonus in modern battery operated, and very much battery life concerned, medical devices. It seems that NFC technology may enable new products having new functionalities and new man-machine inter- faces in the future telemedicine systems to come. Introduction Wireless technology started being appreciated by health care providers and medical devices manufacturers in the late ‘90s, just when mobile phone communications began skyrocketing.

The transmission medium can either be wired or wireless. The network is established and data is transmitted over it with the support of networking hard- ware and the software running on the hardware. Network hardware comprises equipment that generates the signal at the source, transmits the signal over the transmission medium, and receives and processes the signal at the destination. The software comprises protocols, standards, instructions, and algorithms that support transmission services over the net- work. The essentiality of networks has increased over time, along with advancement in network hardware, software, and support applications. There are huge variations in the size of a network in use; there can be small networks confined to an office or home, and at the same time there areCOPYRIGHTED networks spread across cities and MATERIAL countries. The spread of the network can be described in various terms, such as distance covered and the number of computers and other resources connected to the network. A local area network confined to a building may connect thousands of computers, such as in a software development center, a call center, or a stock exchange.

The original Internet architecture has been designed to facilitate the communication between a defined set of network nodes, i.e., the de- sign is host-centric. Today’s dominating use case has become infor- mation retrieval, i.e., an information-centric use case. In this use case, the user is only interested in the information itself; it is irrelevant which node delivers the information as the information itself is node- independent in this scenario. At the same time, this shift has re- sulted in a tremendous traffic increase. The Internet protocol suite handles this traffic inefficiently due to its host-centric design which dictates the data source in advance instead of allowing the network to choose the most suitable data source; i.e., the host-centric design does not fit the information-centric use case. This results in several problems. Especially, the original Internet architecture incorporates neither caching nor the ability to intelligently select the most suitable data source(s), which results in inefficient, redundant transmission of identical content and unnecessarily high network traffic and latency.
