Context awareness in WBANs: a survey on medical and non-medical applications

A Review of State-of-the-Art on Wireless Body Area Networks

“…In addition, data rate, mobility, network topology, node size between two networks is diverse result in different architect to design and implementation. Most importantly, energy source and high reliability and low delay are very critical for WBANs because data mostly consist of medical information and can be as a life threat for patients [16], [17]. Thus, WBANs have several advantages rather than WSNs such as flexibility, effectiveness and cost-effective.…”

“…Data can also be sent in similarly stream and the higher rates posted during the explosion. The reliability of the data transmission for the guarantee of the correct data is received from health-care professionals in term of bit error rate (BER) for the number of lost packets [17]; for medical devices, the reliability is based on the speed of the data. Low data rate can be a high BER (10 -4 ) while devices with higher data rates require a lower BER (10 -10 ) can be gained [16].…”

Cross-layer designs for energy efficient wireless body area networks: a review

“…The context refers to the environment and the patient conditions where the WBAN is deployed (humidity, environment temperature, luminosity, emotions, mental state, stress levels, age and any other extra-information that could help to better characterize the patients situation). In [60], the authors proposed that context-aware strategies should be implemented over energy-efficient cross-layer approaches between MAC and application layers; they claim that crosslayer in context aware scenarios is needed to address limitations like energy consumption, transmission errors and QoS constraints by an efficient communication of parameters between the MAC layer and the application layer. They also mention that little research has been done regarding this matter.…”

An energy-efficiency index based on death probability for maximizing WBAN reward

“…Liu, Yan, and Chen (2013) introduced a context-aware Medium Access Control (MAC) protocol to meet timevarying requirements of WBAN and demonstrated that the proposed protocol was able to reduce latency, energy consumption and packet loss rate, as well as to achieve a reasonable trade-off between energy-efficiency and reliability. Tobón, Falk, and Maier (2013) presented an overview of context-aware solutions at the MAC and application layers. Chen, Zhao, Krishnamurthy, and Djonin (2007) also used random shortest path method to optimise the WSN lifetime and proposed the dynamic protocol for lifetime maximisation (DPLM) that built energy efficiency function based on the network status to optimise the network lifetime .…”
