Broens et al. elaborated on the app

Broens et al. elaborated on the application layer proposed by Maarten, and assumed that the lower layers would supply common functionalities, such as connectivity, context management and service management. The application layer contained three main components: application container, generic container, and domain-specific functions. Although the authors claimed that this context-aware application framework provided an application environment that made development mhealth applications feasible and improved usability, evaluation results were not presented. In this framework, the mobile phone was used as a MBU (Mobile Base Unit) to offer gateway functionality to connect the BAN to the m-health support system.
