Physiological information acquisition through wireless biomedical sensor networks

The monitoring and acquisition of patients' physiological information are quite crucial for the further treatment. Wireless network of biomedical sensors shows great potential to significantly enhance the biometrics performance. Meanwhile, it poses prominent characteristics and challenges to medicos and engineers for its particular medical application compare to other application of wireless sensor networks (WSN). This paper first investigates the exciting conceivable application of WSN in medical area. Then the unique challenges and requirements are analyzed in detail. Along with the further study of the logical architecture and network protocols, preliminary solutions are proposed for the WBSN in a hospital environment.
