A smart system to program Body Sensor Networks

A Body Sensor Network (BSN) must be designed to work autonomously. On the other hand, they must provide mechanisms that allow their control by healthcare personnel, as the clinical assessment of these professionals should always be the basis for the programming strategy. A great challenge in BSN software design is to provide, in a transparent way, access to the internal configurations of the networks and their sensor nodes without excluding their capability for autonomous operation. In BSN´s, the inclusion of this functionality requires a programming interface that is suitable for healthcare personnel, as well as smart compilers. A smart system software compiler to BSN sensor nodes is a recent proposal and its main purpose is to make choices during the software compilation process to increase the effectiveness of the system´s use, considering the application´s requirements, the hardware possibilities and mainly the specialist´s knowledge to increase the applications lifetime. The success of this approach can lead to a paradigm shift, since healthcare professionals will be able to act as the actual programmers and maintainers of the BSN. It´s important to argue that doctors are legally responsible to their patient´s treatment even the treatments are tailored using autonomous systems. The purpose of this paper is to describe implementation details and some computer models that can be used to build smart system software centered in an intermediate-level compiler that could be used to program BSN sensor nodes.
