When the environmental conditions are stable, a typical Wireless Sensor Network (WSN) application may sense and process very similar or constant data values for long durations. Thi...
—Energy conservation is drawing increasing attention in data networking. One school of thought believes that a dominant amount of energy saving comes from turning off network ele...
Electric energy consumed in data centers is rapidly growing. Power-aware IT, recently called `green IT', is widely recognized as a significant challenge. Disk storage is a no...
— This paper presents Pirrus, a replica management system that addresses the problem of providing data availability on a wireless sensor network. Pirrus uses probabilistic failur...
In wireless sensor networks (WSNs), energy consumption and data quality are two important issues due to limited energy resources and the need for accurate data. In this scenario, i...
