Game Theory Optimizes Decentralized Edge Caching Under Budget and Storage Limits

arXiv preprint · 2026

Key Findings

01The game constitutes an exact potential game under light storage constraints, guaranteeing a pure-strategy Nash equilibrium and decentralized convergence.
02Under binding storage constraints, the game loses its potential game structure, but simulations show stable and efficient convergence.
03Convergence behavior is primarily driven by content provider competition, not the scale of edge infrastructure.
04Storage scarcity exacerbates inequality among content providers and increases the bargaining power of edge devices.

Application

Design takeaway

When designing decentralized systems with competing entities and limited resources, model the strategic interactions and economic incentives to ensure efficient and fair resource allocation.

How to apply

Use game theory to model scenarios where multiple independent agents with limited resources must make decisions that affect each other, such as in distributed computing, resource sharing platforms, or supply chain management.

Project actions

01When defining your problem, clearly identify the competing agents and their objectives.
02Consider using game theory to model the interactions if agents' decisions are interdependent and strategic.

Method & Evidence

AimHow can a hierarchical game-theoretic model be used to optimize decentralized edge caching systems considering content provider budgets, edge device storage, and strategic competition?

MethodGame-theoretic modelling and simulation

ProcedureThe researchers formulated a hierarchical game combining a Stackelberg model for content provider-edge device interactions and a non-cooperative game among content providers. They analyzed the game's properties under different storage constraint scenarios and simulated convergence behavior.

ContextDecentralized edge caching systems in mobile social networks

Variables

IVContent provider budgets, edge device storage capacity, storage constraint bindingness.

DVConvergence behavior, economic outcomes (inequality, bargaining power), system efficiency.

CVNumber of content providers, number of edge devices, content popularity distribution, operational costs.

Strengths & Limitations

Strengths

+Provides a formal mathematical framework for analyzing complex decentralized systems.
+Offers insights into the economic implications of resource scarcity and competition.

Limitations

The complexity of real-world interactions might be simplified in a game-theoretic model, potentially overlooking nuances.

Reliability & validity

The reliability of the model's predictions depends on the accuracy of the game's assumptions and the robustness of the simulation. Validity is supported by the theoretical guarantees of potential games under specific conditions and empirical evidence from simulations.

Think critically

How might the assumptions of rationality and perfect information in game theory affect the applicability of this model to real-world edge caching scenarios where users and providers may not always act optimally or have complete information?

Design Principles

"Model strategic interactions and resource constraints to optimize decentralized system performance and equity."

This research provides a robust framework for designing and managing complex distributed systems where multiple entities with competing interests and limited resources must collaborate. Understanding these strategic dynamics is crucial for optimizing performance, ensuring fairness, and achieving economic viability in edge computing deployments.

What This Means for Your Design

Imagine a group of friends deciding how to share a limited number of snacks at a party. This research uses math (game theory) to figure out the best way for different companies to share limited storage space on devices to give people content quickly, even when they have different amounts of money to spend and limited space.

Paragraph starter

This design project employs a game-theoretic modelling approach, inspired by research such as Sedghani et al. (2026), to analyze the strategic interactions and resource allocation among competing entities within a decentralized system. By formulating a hierarchical game, we aim to understand how budget and storage constraints influence outcomes and to identify optimal strategies for efficient and equitable resource distribution.
