Ubiquitous healthcare system using emergency strategy based on wireless body area system

More and more study and application of ubiquitous healthcare system have been based on WBN (wireless body area networks). However, there are several important aspects that should be considered, such as the large amount sensing data, limited mobile terminal power supply, wireless bandwidth for video data flow. In ubiquitous healthcare networks, some personal health-care data are very important, such as body temperature, vital capacity, respiration signal, maximal oxygen uptake, etc. How to effectively transmit and analyze the personal health information using wireless sensor terminal is the difficult task. In this paper, we realize the ubiquitous networks to process these health data. The strategy of multi-users choosing is the main problem. Extensive simulations are also conducted to evaluate the performance in terms of fault probability, throughput, and mobile healthcare network utilization.
