ABSTRACT
Body sensors have gained increasing interest during the past several years. With more applications deployed, it is imperative to ensure the success of data analysis, which largely depends on data transmission reliability as well as the importance of samples received. Traditional approaches focus on improving data reliability through various schemes such as prioritization of MAC access. In this paper, we analyzed the characteristics of time series body sensor data and propose to rank sample importance based on a multi-level approach. With this approach, samples are grouped into five levels, indicating their importance with regard to data analysis. Then, a progressive transmission strategy is designed to transmit samples in order of their importance so that the overall received data quality is maximized. Preliminary simulation results indicate that as much as 40–60% bandwidth saving can be achieved while meeting the requirements of data analysis algorithms.
