The development of a wireless sensor network (WSN) gateway is challenging for sites where limited infrastructures lead to frequent power shortages and and network unreliability. In this paper we present a low-power, low-cost, 802.15.4 and 802.11 compatible solution which uses open source software to meet local conditions. Using the SunSPOT motes on a system which is mostly platform independent, our system is based on the Fox embedded Linux board and equipped with a USB flash drive and a USB WiFi adapter. The system can be solar-powered, and the results of a solar system design are presented. All the hardware components are available off-the-shelf and are easy to assemble. We conclude that our system is preferred for applications in remote areas, where a stable power supply and a reliable network infrastructure are lacking. Furthermore, it can be used to extend the range of wireless sensor networks by layering a network of long range motes above islands of low range motes.
