We study the design of incentive mechanisms for problem information elicitation without verification (IEWV). In IEWV, a data requester seeks to proper incentives optimize tradeoff between quality (collected from distributed crowd workers) and total cost (provided verifiable ground truth. While prior work often relies on sufficient knowledge worker information, we scenario where cannot access workers' heterogeneous costs ex-ante. propose continuum-armed bandit-based mechanism that dynamically...

Conventionally, mobile network operators charge users for data plan subscriptions. To create new revenue streams, some now also incentivize to watch ads with rewards and collect payments from advertisers. In this work, we study two such rewarding schemes: a Subscription-Aware Rewarding (SAR) scheme Subscription-Unaware (SUR) scheme. Under the SAR scheme, only subscribers of operators' existing plans are eligible rewards; under SUR all (e.g., who do not subscribe can still get SIM cards...

To address the increasingly severe congestion problem in cellular networks, mobile operators are actively considering offloading traffic to other complementary networks. In this paper, we study online network selection operator-initiated data with multiple users, taking into account operation cost, queueing delay, and load different access networks (e.g., macrocell, femtocell, Wi-Fi networks). We first design a Delay-Aware Network Selection (DNS) algorithm based on Lyapunov optimization...
