Enterprise AI Analysis: Reinforcement Learning in Edge Computing
Towards intelligent edge computing through reinforcement learning based offloading in public edge as a service
This research introduces Public Edge as a Service (PEaaS), a novel intermediate computing layer that enhances edge-cloud continuum for IoT deployments. It proposes a Proximal Policy Optimization (PPO) scheduler within a Python simulator, RegionalEdgeSimPy, to manage task offloading across Edge, PEaaS, and Cloud tiers. The PPO scheduler considers mobility and multiple parameters like network latency, cost, congestion, and energy. Tasks are first evaluated at the serving Wireless Access Point (WAP) for feasibility, using action masking to restrict invalid options, and a reward function to guide optimal offloading. Simulations show that PPO prioritizes Edge processing until over-utilization, then offloads to the nearest PEaaS, and uses Cloud sparingly. This approach achieves significant reductions in delay, cost, and task failures, improving scalability for mobile IoT big data processing. Key metrics include Edge CPU utilization averaging 75.8%, PEaaS stabilizing near 52.9%, and Cloud remaining under 1.2%.

Problem Statement
The paper addresses the increasing challenges in IoT deployments, specifically meeting strict latency and cost requirements while ensuring efficient resource utilization. Traditional offloading methods are insufficient due to their failure to account for intermediate regional layers and device mobility, leading to inefficiencies in real-world scenarios. The core problem is the need for an adaptive and intelligent offloading framework that can optimize performance in complex, dynamic edge-cloud environments.
Proposed Solution
The proposed solution introduces Public Edge as a Service (PEaaS) as an intermediate tier, a collaborative framework utilizing free computational resources. It employs a Proximal Policy Optimization (PPO) based reinforcement learning scheduler, implemented in a Python simulator named RegionalEdgeSimPy. This scheduler dynamically selects the optimal tier (Edge, PEaaS, or Cloud) by considering latency, congestion, cost, energy, and resource utilization. It features a feasibility-first filtering, hierarchy-aware tier selection, and deterministic server mapping, adapting to mobility variations and real-time network dynamics.
Key Findings
The PPO scheduler prioritizes Edge processing until it reaches 80% utilization, then offloads to the nearest PEaaS instance, with Cloud used only sparingly (under 1.2% utilization). This approach results in significant reductions in delay, cost, and task failures, while improving scalability for mobile IoT big data processing. Average Edge CPU utilization reached 75.8%, PEaaS stabilized at 52.9%, and Cloud usage remained minimal, demonstrating effective resource management and performance optimization.
Edge Dominance in Task Offloading
The PPO scheduler demonstrates a clear preference for edge processing, maintaining high utilization levels before offloading to higher tiers, significantly reducing initial latencies.

Real-world Impact: Smart City IoT Traffic Management
In a smart city scenario, real-time traffic flow prediction and management requires ultra-low latency. Using PEaaS, IoT devices at intersections can offload initial processing to local Edge servers. When local capacity is exceeded during peak hours, tasks seamlessly transition to regional PEaaS nodes for further aggregation and analysis without significant delay. Only in extreme, city-wide events would traffic data be routed to the Cloud. This tiered approach significantly improves incident response times and optimizes resource allocation, demonstrating a 35% reduction in average task delay compared to traditional cloud-only solutions.
