Development of an internet gateway for a wireless sensor network

Abstract

Wireless Sensor Networks (WSNs) are being employed frequently to gather data from an ever-increasing variety of environments and phenomena. \iVSNs offers users in the industrial and academic community a low power, unobtrusive, adaptable and wireless alternative to traditional sensing equipment. This study focuses on the development of a configurable, low power and cost-effective gateway that will link a WSN to the Internet. In addition, the gateway provides onsite storage for the data collected by the WSN which may be uploaded at a scheduled time to a computer at a specified Internet address through a GSM or Ethernet link. Furthermore, the gateway provides a suitable platform capable of executing a variety of multitasking operating systems such as Windows Embedded CE or Linux. This multi-platform support permits the gateway the flexibility, through custom user applications, to adapt its functionality to the requirements of a WSN elm I the environments into which these networks may be deployed. This study has been successful in the design and development of a low-cost gateway solution, allel has produced a functional prototype system,
