Health monitoring using WBAN: topology design, routing and thermal issues
The developments that shaped the twenty/twenty-first century with respect to wireless technologies have had a great influence on quality of life, where wireless body area networks (WBANs) - implantable sensor nodes, more specifically, have recently emerged as a successful initiative for monitoring health remotely, and thus a research challenge. Two concerns that need addressing here are heat dissipation which causes damage to surrounding tissues, and introduction of relay nodes to increase network lifetime, but on the other hand may cause health hazards. There arises a need to find an efficient network topology design to overcome the above-mentioned concerns. This chapter discusses in detail WBAN, its applications, related technologies, energy-aware topology design, efficient relay node placement methods and, last but not least, energy-efficient and thermal-aware routing techniques.
