What is Energy Efficiency in Computing?
Energy efficiency in computing refers to the development of models and algorithms designed to reduce power consumption in computing systems such as peer-to-peer systems, wireless sensor networks, fog computing in IoT, virtual machines, and dynamic server clusters.
Research in this field encompasses 2,261 works focused on energy-efficient server selection algorithms, computation models for virtual machines, and strategies for dynamic clusters of servers. Key areas include power management in memory systems and applications in ubiquitous computing environments. Growth rate over the past five years is not available from the data.
Topic Hierarchy
Research Sub-Topics
Dynamic Voltage and Frequency Scaling
This sub-topic examines techniques for dynamically adjusting processor voltage and frequency to minimize power usage while preserving performance in computing systems. Researchers develop algorithms and hardware controls for real-time adaptation in CPUs, GPUs, and mobile devices.
Energy-Efficient Server Selection Algorithms
This area focuses on algorithms that select optimal servers in cloud and distributed systems based on power consumption, load, and location metrics. Studies analyze trade-offs between energy savings, latency, and cost in large-scale deployments.
Power Management in Wireless Sensor Networks
Researchers investigate protocols, routing, and scheduling methods to extend battery life in resource-constrained wireless sensor networks for IoT applications. Key studies cover duty cycling, data aggregation, and topology control strategies.
Energy Models for Virtual Machines
This sub-topic develops accurate computational models to predict and optimize power consumption of virtual machines in cloud environments. Research includes measurement-based modeling, migration strategies, and consolidation techniques.
Energy Efficiency in Fog Computing
Studies explore distributed computing paradigms at network edges to minimize latency and power in IoT-fog architectures. Researchers focus on task offloading, resource provisioning, and edge caching optimized for energy constraints.
Why It Matters
Energy efficiency in computing addresses thermal and electrical constraints in enterprise server architectures, where datacenter operators face rising energy costs. David et al. (2011) demonstrated memory power management via dynamic voltage/frequency scaling, showing that voltage/frequency adjustments can reduce energy use across systems while maintaining performance. This approach supports energy-proportional computing, enabling scalable operations in data centers handling petabyte-scale data, as seen in platforms like Google Earth Engine which process vast satellite imagery catalogs for planetary analysis (Gorelick et al., 2017). Applications extend to IoT fog computing and wireless sensor networks, reducing power draw in pervasive systems.
