Non-cooperative Game For Capacity Offload
Feng Zhang, Wenyi Zhang, Qiang Ling

TL;DR
This paper models the competition among wireless service providers for unlicensed spectrum using non-cooperative game theory, analyzing equilibrium existence, structure, and convergence of best-response dynamics in capacity offload scenarios.
Contribution
It formulates the capacity offload problem as a non-cooperative game, characterizes Nash equilibria, and analyzes convergence properties of best-response dynamics for multiple players.
Findings
A pure-strategy Nash equilibrium always exists in the game.
Alternating-move best-response dynamics converge to NE in two-player scenarios.
Simultaneous-move dynamics may not converge when multiple NEs exist.
Abstract
With the blasting increase of wireless data traffic, incumbent wireless service providers (WSPs) face critical challenges in provisioning spectrum resource. Given the permission of unlicensed access to TV white spaces, WSPs can alleviate their burden by exploiting the concept of "capacity offload" to transfer part of their traffic load to unlicensed spectrum. For such use cases, a central problem is for WSPs to coexist with others, since all of them may access the unlicensed spectrum without coordination thus interfering each other. Game theory provides tools for predicting the behavior of WSPs, and we formulate the coexistence problem under the framework of non-cooperative games as a capacity offload game (COG). We show that a COG always possesses at least one pure-strategy Nash equilibrium (NE), and does not have any mixed-strategy NE. The analysis provides a full characterization of…
