ABSTRACT
Over the last few years, the vast majority of smart devices has been equipped with a variety of sensors, including accelation, light and gravity sensors, magnetometers etc. Moreover, mobile smart devices possess high computational power, storage in the order of gigabytes, whereas high battery capacity and high bandwidth are available. The biggest advantage of the wide presence of mobile smart devices is that all this distributed computing power is already at hands of people, being idle for the most time. This fact presents a chance of utilizing this distributed computational infrastructure with the goal of building participatory sensing systems with various applications for enviromental support, like health or structure monitoring. In this paper we are presenting a generic distributed framework consisting only of mobile smart devices and operating only in the network. We utilize a scalable, fault-tolerant communication protocol, that performs best-effort time synchronization of the nodes and present a first approach in an example application of distributed structural health monitoring (SHM).
