A web service based gateway architecture for wireless sensor networks

This paper 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.
