A survey of open body sensor networks: Applications and challenges

Originated from Wireless Sensor Networks (WSNs), Body Sensor Networks (BSNs) have been applied to numerous domains. However, after an in-depth analysis of the state-of-the-art, several factors have been found to limit the development of applications based on BSNs. In this paper we introduce the concept of Open BSNs for improving the development of BSNs. Specifically, open BSNs can improve key aspects such as energy efficiency, system interoperability, system usability and scalability, and privacy support. Application scenarios and future research challenges of Open BSNs are also presented.
