Communication and processing consideration for alerting systems implemented through mobile sensor networks

摘要

At the beginning of the paper it is presented an alerting system architecture based on mobile sensor network. Then it is analyzed the current available radio communication infrastructure which can be used for implementation of alerting systems in conjunction with the alerting systems requirements. Further we shown how the digital signal processor (DSPs) are the best fit for the processing level We propose some ideas of selection criterion bused on this analyze and an implementation of a mobile sensor network with applicability in alerting systems. Built with the purpose of surveillance, data gathering and warning, alert systems could benefit from the increase flexibility offered by a mobile sensor network. In order to ensure a low cost and an extended battery life, for communication between nodes the ZigBee standard was chosen. For the prompt response of the system we design a software kernel with real time operation and implement on DSP architecture.
