Energy Efficiency in Fog Computing
Research Guide
What is Energy Efficiency in Fog Computing?
Energy Efficiency in Fog Computing optimizes power consumption in distributed edge computing systems that process IoT data near the source to reduce latency and cloud dependency.
Research centers on tree-based fog models, task scheduling, and fault-tolerant resource allocation for IoT environments (Oma et al., 2018, 132 citations). Key works include energy-efficient scheduling algorithms (Verma et al., 2016, 127 citations) and dynamic tree models (Oma et al., 2020, 17 citations). Over 10 papers from 2016-2023 explore these approaches, with Oma et al. dominating fault-tolerant designs.
Why It Matters
Energy-efficient fog computing enables sustainable IoT deployments in smart cities and healthcare by minimizing power use at edge nodes (Oma et al., 2018). It supports real-time applications like remote monitoring without cloud reliance, reducing latency and costs (Verma et al., 2016). Resource allocation models improve scalability for educational fog environments (Shruthi et al., 2022). Flexible models cut IoT energy by up to 30% in fault scenarios (Duolikun et al., 2023).
Key Research Challenges
Dynamic Resource Provisioning
Fog nodes face variable IoT loads requiring adaptive allocation to avoid energy waste. Scheduling algorithms struggle with real-time balancing (Verma et al., 2016). Weighted greedy knapsack methods help but overlook multi-tenant priorities (Shruthi et al., 2022).
Fault Tolerance in Trees
Tree-based fog models need recovery mechanisms that preserve energy during node failures. Energy-efficient recovery algorithms extend lifetimes but increase overhead (Oma et al., 2019). Fault-tolerant designs trade off computation for reliability (Oma et al., 2018).
Scalable Energy Modeling
Modeling energy in mobile and dynamic fog requires flexible structures like DTBFC. Evaluations show trade-offs between tree depth and consumption (Oma et al., 2018). Recent flexible models reduce consumption but complicate deployment (Duolikun et al., 2023).
