The deployment of several biosensors on the human body for the collection of physiological data forms what is called a Wireless Body Area Network (WBAN). Thus, to ensure wireless communications between the different components of WBANs, the IEEE has established the IEEE 802.15.6 standard, which is an optimized communication standard for low-power devices that operate on, in, or around the human body (but not limited to humans). In this context, several simulation studies have been conducted in the literature to analyze and evaluate the performance of the IEEE 802.15.6 CSMA/CA access scheme. Also, efforts have been made to model this scheme to better analyze the characteristics of the standard in a more general context. However, these models are partially applicable to WBANs applications with heterogeneous network traffic.This thesis deals mainly with a challenge related to the modeling of the IEEE 802.15.6 standard to provide a tool for evaluation and analysis of this standard in various channel conditions and situations. We have tried, through the main contributions made in this thesis, to address the shortcomings noted in existing work as follows: the first contribution concerns an evaluation of the performance of the IEEE 802.15.6 standard using numerous queue management strategies, in a realistic medical setting (home monitoring of a patient with a heart problem). The second contribution proposes an LLQ (Low Latency Queuing) queue management model as a complement to the CSMA/CA protocol to efficiently meet the requirements of the standard in terms of Quality of Service (QoS) for certain types of applications.The third contribution deals with the proposal of an analytical model allowing the study of the CSMA/CA access scheme of the IEEE 802.15.6 standard, in terms of latency and packet delivery rate under the assumption that WBANs are composed of heterogeneous nodes and that each of them generates heterogeneous traffic in terms of priority.The last contribution proposes a security protocol called "Server-Based Secure Key Management for the IEEE 802.15.6 standard" (SBSKM) that allows the standard to address the vulnerability of impersonation attacks, by including a trusted server, responsible for the creation, initialization, and distribution of encryption keys and their renewal, as well as to guarantee the identity of sensors joining the network.Keywords: Body Area Networks (WBANs), IEEE 802.15.6 standard, renewal reward process, priority queues, and impersonation attacks.

This book explores the design of ultra wideband (UWB) technology for wireless body-area networks (WBAN). The authors describe a novel implementation of WBAN sensor nodes that use UWB for data transmission and narrow band for data reception, enabling low power sensor nodes, with high data rate capability. The discussion also includes power efficient, medium access control (MAC) protocol design for UWB based WBAN applications and the authors present a MAC protocol in which a guaranteed delivery mechanism is utilized to transfer data with high priority. Readers will also benefit from this book’s feasibility analysis of the UWB technology for human implant applications through the study of electromagnetic and thermal power absorption of human tissue that is exposed to UWB signals.

The proliferation of ubiquitous sensing devices along with advances in low power wireless communication technology have resulted in the extensive use of wireless body area networks (WBANs) as the building blocks of the emerging field of wireless health. In these battery-operated WBANs, the sensor devices are strategically placed in/on the human body and the short/mid/long wireless communications are conducted on/off the surface of the body. As the battery energy does not follow Moore's law, energy-efficiency is always one of the design challenges of wireless health-monitoring systems, impacting usability, security, and cost. The idea of transmission power control (TPC) is to automatically reduce the radio amplifier's output power when the transmission power is more than required. Reduced transmission power translates into more energy savings and reduced interference problems. TPC techniques have been used in abundance in cellular networks and wireless LANs. TPC schemes for WBANs, however, are still in their infancy. For example, current IEEE 802.15.4 specifications do not differentiate between mobile and static settings, thus leaving WBAN transmitters in the dark as to what transmission power level they should utilize. In this dissertation, we have investigated the potential benefits and limitations of TPC as a means to extend the battery lifetime in WBANs at the first three abstraction levels. Physical and MAC layers' approach to TPC perform a local optimization, whereas network layer TPC is capable of a global optimization. At the network layer, we analytically solve an optimization problem whose solution determines an important parameter, i.e., energy-efficient cluster size, for a class of routing/MAC protocols in WBANs. Assuming that the routes are established in an energy-efficient manner, we then experimentally profile the 2.4 GHz on/off-body radio channel under several scenarios regarding mobility states and environments, and we showed that fixed transmission power either wastes energy or hinders reliability. Finally, we devote our attention to an ambulatory medical monitoring WBAN system, which is tied up with different characteristics in terms of mobility, periodicity, and `unforgivingness' of the wireless channel as a result of proximity to the ground as well as to human's body. The target ambulatory WBAN system encompasses a pair of wireless instrumented insoles (known as smart insoles) for gait data collection, plantar pressure monitoring, and gait analysis. We design a sensor-assisted TPC scheme that augments in-network information with information from built-in sensors. To this end, multiple mobility states are defined for the smart insoles and the mobility states are incorporated into transmission power control policies. Available sensor information is leveraged to detect the mobility states, based on which the TPC scheme switches strategies. We validate this new idea of switching transmission power control strategies by implementing and evaluating the sensor-assisted scheme and comparing it against a frame-based TPC scheme, which adjusts the transmit power solely based on recent information about packet transmission successes and failures. Our testbed experiments involving mixed mobility scenarios show that our TPC scheme obtains up to 50% increase in the battery lifetime, enabling the smart insoles to be used in uncontrolled environments. Such an improvement in battery longevity (from 4.0 hours to 7.8 hours) is made by reducing the average energy consumed for communication of a single packet from 4.51 mJ/pkt to 2.27 mJ/pkt. Although designed for the smart insoles as a severely energy-constrained device, the sensor-assisted TPC technique is readily deployable on a variety of today's commodity devices to make a connection between the sensing subsystem and the communication subsystem of such devices. In addition, as the underlying mobility state detection methods place relaxed requirements on how the device should be worn in terms of orientation and position, they can be used for a variety of purposes, such as improving the patient's compliance with medical treatments and therapies.

Wireless sensor and body area networks (WSN and WBAN respectively) have been seen as a future way to monitor humans’ psycho-physiological signs remotely. There are a number of standards that could be used for building WBAN sytems. However, wireless UWB networks based on IEEE 802.15.4a offer the advantages of a large frequency range and low power spectral density, making it suitable for both WSNs and WBANs used for medical applications. The technology has matured sufficiently that it can be used to develop products for the marketplace. This book presents how the IEEE802.15.4-2011 (former IEEE802.15.4a) can be used in wireless body area networks (WBAN) for healthcare and welfare related applications.
