    Recent advances in Micro-Electro-Mechanical Systems (MEMS) technology, integrated circuits, and wireless communication have allowed the realization of Wireless Body Area Networks (WBANs). WBANs promise unobtrusive ambulatory health monitoring for a long period of time and provide real-time updates of the patient's status to the physician. They are widely used for ubiquitous healthcare, entertainment, and military applications. This paper reviews the key aspects of WBANs for numerous applications. We present a WBAN infrastructure that provides solutions to on-demand, emergency, and normal traffic. We further discuss in-body antenna design and low-power MAC protocol for WBAN. In addition, we briefly outline some of the WBAN applications with examples. Our discussion realizes a need for new power-efficient solutions towards in-body and on-body sensor networks.Comment: 7 pages, 7 figures, and 3 tables. In V3, the manuscript is converted to LaTe

    IEEE International Conference on Communications (IEEE ICC 2015). 8 to 12, Jun, 2015, IEEE ICC 2015 - Communications QoS, Reliability and Modeling, London, United Kingdom.IEEE 802.15.6 facilitates communication in the vicinity of or even inside a human body to serve heterogeneous medical, consumer electronics, and entertainment applications. This standard operates in beacon and non-beacon communication modes, and each mode employs different protocols, including CSMA/CA, for resource allocation on the channel. The CSMA/CA protocol presented in IEEE 802.15.6 allows quick and prioritized access to the channel by differentiating contention window bounds of nodes with different priorities. This paper provides a simple and accurate analytical model to estimate the throughput, energy consumption, and delay of this protocol for different priority classes, under the assumption of a finite number of nodes in saturated and lossy channel conditions. The accuracy of the proposed model is validated by simulations. The results obtained in this paper can be used to design standard priority parameters for medical and non-medical applications
