Abstract
In nowadays applications of Wireless Sensor Networks (WSN), the client makes use of sensing data in Internet. A network gateway is required to connect WSN to Internet for data exchanging. In conventional studies, they usually apply personal computer as the network gateway. This model has shortcomings in high cost, large size, and high energy consumption. It is a meaningful research issue to make an improvement on these shortcomings. This thesis tries to modify the firmware of a Wireless Local Area Networks Access Point (WLAN AP), and make it as the network gateway of WSN and Internet. We call this WLAN AP as WiZAP (WiFi ZigBee Access Point). Even though the computation ability and memory resource provided by WiZAP is not as sufficient as PC, WiZAP has low cost, small size, and low energy consumption. This thesis introduces the WiZAP architecture that provides modularity and low cost methods to connect WSN with Internet and supply users not only Internet services but also WSN functions. By adjusting the parameter of MAC layer in WiFi, we propose some observations to avoid data collision when Zigbee and WiFi coexist. We make a comparable analysis of research associated with the architecture, and show the advantage such as high flexibility, low cost, convenient to build, and low energy consumption.
