Design of Multiterm Spectrum Resource Trading Contracts in UAV-Enabled IoT
Weibo Hao, Fang Ye, Yuan Tian · IEEE Internet of Things Journal · 2024
The unmanned aerial vehicle (UAV), serving as an aerial platform, is capable of assisting IoT devices in providing global emergency coverage. To incentivize the macro base station (MBS) operator to lease idle spectrum resources to the UAV operator, an appropriate cross-layer spectrum trading mechanism needs to be established. To address the time-variation and asymmetry of information in spectrum trading, this article adopts multiterm contract theory to analyze this issue. We formulate the problem of designing multiterm optimal trading for these three scenarios: 1) 1-D static transactions; 2) multidimensional static transactions; and 3) dynamic transactions. We employed deviations instead of derivatives to decompose the original problem into several subproblems. Based on the numerical results, we conclude that multiterm transactions cannot be simply decomposed into repeated single-term transactions. The optimal contract design should fully consider the composition of private information in multiterm transactions, as well as obtaining discounts from future revenue commitments.
