The evolution of wireless network protocols such as Bluetooth and ZigBee, and the reducing size, cost (and power consumption) of small scale sensor devices means that new approaches to healthcare monitoring and provision are now possible. From the technological side, new wireless devices can be envisaged that can monitor patients both externally (in terms of movement, flexibility and mobility) and even internally (in terms of embedded devices). From the health and social care side, such wireless devices can allow home monitoring of patients. This can allow more efficient and effective use of health and social care professionals, and also allow patients in remote areas to potentially receive as much healthcare monitoring as patients in urban environments. However, it is important that any use of such new technologies is carefully piloted and integrated with traditional health and social care approaches, especially in terms of the reliability and security of patient data. In this chapter, the authors provide a discussion on the state-of-the-art research initiatives that are trying to address these challenges. A discussion is presented on some of the more recent background work and a view of what future body area networks and smart environments might look like. Throughout the discussion the authors present the challenges faced by many research communities and the likely trends that will emerge given such challenges.
