Analyzing the Effect of Increased Distribution on a Wearable Appliance

Wearable Systems are important tools to increase the reach of Computer Science into helping other research fields. In this context, System-on-Chips with embedded low-power processors are useful tools to develop prototypes and solutions. Nevertheless, the limited resources of these systems create a limit on the speed and quality of the gathered information. A possible alternative for this problem is to increase the number of embedded computers composing the system, distributing the workload between different nodes. In this study, we analyze the effect of increased distribution on the main wearable constraints using a prototype. In order to investigate the energetic impact of increased distribution, we perform a long-run test. Also, we propose a novel testbed based on the Quality-of-Service (QoS) concepts and use it to analyze the effect of this increased distribution in communication and synchronization performance.
