As an increasing number of electronic systems are powered by batteries, battery life becomes a primary design consideration. Maxiimizing battery life requires system designers to develop an understanding of the capabilities and limitations of the batteries that power such systems, and to incorporate battery considerations into the system design process.(More)
Since battery life directly impacts the extent and duration of mobility, one of the key considerations in the design of a mobile embedded system should be to maximize the energy delivered by the battery, and hence the battery lifetime. To facilitate exploration of alternative implementations for a mobile embedded system, in this paper we address the issue(More)
The growing popularity of Wireless LAN-based connectiv-ity has increased the use of IEEE 802.11b as an edge access technology. However, with the ability to support high data rates and a wide range of applications, data access in these networks poses a significant demand on limited energy resources of mobile devices. In addition to the application demand,(More)
Future wireless applications, such as cellular video telephony, wireless LANs and PANs, home networks, and sensor networks, point towards a growing demand for multimedia content in wireless communication. However, mobile multi-media communication has several bottlenecks including bandwidth requirements, low-power constraints, and channel noise. In this(More)
—One of the main challenges in adoption and deployment of wireless networked sensing applications is ensuring reliable sensor data collection and aggregation, while satisfying the low-cost, low-energy operating constraints of such applications. A wireless sensor network is inherently vulnerable to different sources of unreliability resulting in transient(More)
—Wireless Sensor Networks are a fast-growing class of systems. They offer many new design challenges, due to stringent requirements like tight energy budgets, low-cost components, limited processing resources, and small footprint devices. Such strict design goals call for technologies like nanometer-scale semiconductor design and low-power wireless(More)
