4 Technical Challenges Facing BSN Although the BSN platform aims to provide the ideal wireless setting for the networking of human body sensors and the setting up of pervasive health monitoring systems, there are a number of technical challenges that lie ahead. These include the need for better sensor design, MEMS integration, biocompatibility, power source miniaturisation, low power wireless transmission, context awareness, secure data transfer, and integration with therapeutic systems, each of which are mentioned briefly below, and covered in more detail throughout this book.

In terms of security, BSN data must be secured with strong cryptography to protect the patient’s privacy. However, strong cryptography requires extensive computation and resources. Considering the limited resources that a BSN node can have, a compromised approach has to be taken to maximise security whilst minimising resource utilisation. Furthermore, the highly dynamic nature of the BSN means that typically static network authentication methods will not be applicable. Even methods proposed for ad hoc networks such as the asymmetric cryptography technique would be computationally too expensive for BSN applications [61].

Nanoscale particles are likely to be the smallest component of sensing systems and may be deployed in a number of ways. For example, nanoscale particles may themselves be coated to form a biomechanical sensing system. An existing example of this is a protein-encapsulated single-walled carbon nanotube sensor that alters its fluorescence depending on exposure to glucose in the surrounding tissues [32]. In fact nanoparticles have even been attached to antigen amyloid-derived diffusible ligands in order to develop a nanoscale optical biosensor for Alzheimer’s disease [75].
