| This project provides a novel method to access ZigBee based wireless sensor networks (WSN) from the Internet using web service approach. We designed a novel gateway between the WSN and the Internet mainly for the scenario of home and building automation. With the improvement of the traditional gateway, the users on the Internet can access the data of the sensor networks flexibly via web services. Each node in the WSN has a unique IP as its identifier, and it can be accessed by the IP directly.
A set of system design requirements were developed that cover the hardware design of the nodes, the design of the sensor network, and the capabilities for remote data access and management. We propose a system architecture that addresses these requirements in general. The application-driven design exercise serves to identify important areas of further work in power management, data sampling, communications, network retasking, and health monitoring.
