Frequency spectrum distribution investments: Evidence from an agent-based experimental economy model

Анотація

In 5G communication systems, one key feature is to establish viable spectrum trading platform, where would the operators and end-users negotiate about the spectrum availability, quality and finally the price over a short timescale. Our motivation is to investigate the impact of the different spectrum pricing strategies on the operator's strategic decisions in terms of the Sharpe ratio indicator. To be able to numerically quantify Sharpe ratio, we constructed the agent-based model of dynamic spectrum access (DSA) market, where the operators lease the frequency resources from the spectrum exchange server (SpecEx) and end-users are capable of the operator switching based on the preferable utility and price. The numerical experiments suggest that the strategic decision of the operators are influenced by the pricing strategy adopted on the retail market and at the same time the operators adopting different pricing strategies can be classified as either risk-seeking or risk-averse.
