    • A key issue in research around embedded Internet systems (EIS) is to reduce power consumption. We envision EIS devices with lifetimes in the range of months or even years. This calls for developing aggressive power management techniques with a high degree of context awareness. As a first step towards this goal we introduce a design methodology for making context aware power optimizations of EIS. The presented design methodology which is verified by experimental results is a promising first step in prolonging operating time of battery powered wireless EIS.

    • By using a sensor connected to a generic wireless embedded Internet system (EIS) platform, data can be presented on-line over the Internet using a standard WWW-browser. When started, the EIS device automatically searches and connects to other devices providing Internet connectivity. The EIS can also provide Internet access for other devices, for example other EIS platforms, thus creating a local network. In this paper we focus on mobile phones with GPRS as the means for wireless Internet connectivity as it provides enhanced area coverage in today's networks. To overcome the problem of non-public IP addresses, a basic server based solution is developed. Our experiments confirm that within GPRS coverage, the EIS device successfully provides Internet access and presents data for on-line monitoring over the Internet.
