Analysis and implementation of a wireless sensor network with remote access through SMS

The use of wireless sensor networks for monitoring physical and chemical parameters in large regions far from populations allows for real-time monitoring with high levels of spatial resolution. This paper presents WubiNet, a wireless network designed for monitoring large regions. Depending on the available infrastructures, the network can be operating for two years using only batteries, or its coordinator can be powered by solar cells to guarantee the transmission of the collected data by SMS using GSM/GPRS technology or satellite phones. The data are transmitted to a base station located out of the range of the node transceivers, where can be represented and analyzed.
