Abstract
A Wireless Sensor Network (WSN) Gateway is treated as the most crucial entity of the WSN network, since it facilitates Data Storage, WSN Network Management and InterConnectivity to a back-end network. Most of the Gateway designs are implemented using a High End Processor and Operating System, to provide reliable data aggregation from the WSN. This paper, discusses the feasibility of using a low power, micro-controller as the Gateway, to provide reliable data aggregation in the face of challenges such as limited power supply, intermittent back end network connectivity and outdoor deployment conditions. In addition, the paper also discusses various mechanisms employed, to ensure that the system recovers and self-heals, when confronted with on-field failures. Finally, debug mechanisms, supplemented by various technologies are implemented and discussed, to provide additional and important on-field and off-field information.
