Abstract:
We propose a spectrum enforcement framework across multiple channels by mobile, crowdsourced agents (also called volunteers), who work in collaboration with a trustworthy infrastructure. The success of spectrum sharing relies on the automated enforcement of spectrum policies. The primary challenge addressed here is to ensure efficient ex post spectrum enforcement. In order to achieve this, we focus on attaining maximum coverage of the area of enforcement and of all channels, and on ensuring reliable and accurate detection of spectrum violation. Maximum coverage of the given area of enforcement is ensured by proposing to divide it into smaller regions using the Lloyd’s algorithm and solving the enforcement problem by a divide and conquer mechanism over the entire area. We determine the qualification of volunteers based on their likelihood of being in a region, and on their trustworthiness. We define algorithms to select qualified volunteers for every region in an online manner such that every channel is efficiently covered. The enforcement framework is simulated in CSIM19 (C++ version) and extensive analysis of the performance of the proposed methodologies is performed.
