面向人体运动干扰和生物安全的无线体域网协作通信技术研究

There are critical requirements for wireless body area networks, such as various traffics, high QoS level and radio security. Thus, both low energy design and reliable communication are needed to resolveprimarily. The cooperative communication in wireless body area network is studied in this program to make the body area communication efficient, safe and reliable under human movement conditions. The relationship between human motions and channel fading is studiedfirstly, and a relay selection algorithm based on channel correlation is proposed; Then, the coding-cooperative method is used to relay communication, and the minimum cost network coding which is suitable in body area network applications is researched to achieve the low power and reliable communications suffering the human movements interference; Finally, all the algorithm and the solutions are verified on the network simulation platform and application testing platform. The achievements about highly reliable communications under human motions will make important role in popularizing wireless body area applications.
