    Radical improvements in battery technology are unlikely—their energy density is already very high. Incremental improvements are likely, but some of those improvements will be eaten up by the energy demands of increased functionality in mobile devices. It is therefore essential to explore alternative approaches to extending battery life. View full abstract»

    Pervasive computing aims to integrate computation into our daily work practice to enhance our activities without being noticed. In other words, computing becomes truly invisible. Yet at the heart of every pervasive computing system are electronic components that consume energy. Managing the energy needs of mobile systems, or systems for which reliable power isn’t guaranteed, can be a signific... View full abstract»

    One of the many challenges associated with sensor networks is how to transmit data and power the sensors. Sensing multiple parameters in the environment requires miniaturized sensor nodes, relatively powerful programming platforms to interface with and process the data, and reliable long-term power solutions. Batteries provide the most obvious power source as long as the modules are reasonably big... View full abstract»

    Mobile devices are becoming increasingly popular, from laptops, PDAs, and cell phones to emerging platforms such as wireless sensor networks. Available battery energy has become a critical mobile-system resource. A mobile device's usefulness is often limited not by its hardware's raw speed but by its battery's energy. Energy consumption is a major systems-design challenge. We designed our ECOSyste... View full abstract»

    Funding initiatives often drive large-scale research agendas in both academia and industry. In many instances, these initiatives arise from projects led by a few individuals who articulate a compelling vision of the future. In our fields, the late 1980s and early '90s provided several such visions and demonstrations. Mark Weiser at Xerox PARC (Palo Alto Research Center) coined the term ubiquitous ...

    With the invention of the PC and emergence of the network, we realized we need new concepts and capabilities to program networks of computers. Standards such as TCP/IP and IEEE 802 played a major role in transforming the first computer network concept (Arpanet) to the Internet we know today. However, we also had to invent new computing models such as the client-server model, transactions, distribu... View full abstract»
