Abstract: One of the most active sharing economy sectors is bike sharing, which is different from ride sharing. This business model, enabled by mobile Internet and cloud computing platforms, seeks vehicle supplies at matching times…
Abstract: Periodic beaconing is essential for neighbor tracking as vehicular communications become widespread. Vehicles periodically broadcast their kinematic data, and receivers estimate their position. Beaconing neighbors requires small position errors and transmission delay for safety….
Abstract: Mobile crowdsensing (MCS) systems require worker incentives to achieve good truth discovery performance. Most incentive mechanisms only compensate workers for sensing costs, neglecting privacy leakage costs. No privacy-preserving incentive mechanism has personalized worker payments…
Abstract: The Internet of Underwater Things (IoUT) will enable naval military, scientific, and commercial applications. Since these systems use traditional batteries, powering them in deep water remains a challenge. This project describes the first batteryless…
Abstract: To meet the tremendous demand of Internet of Things (IoT) applications, the 3rd generation partnership project (3GPP) has specified the narrowband IoT (NB-IoT) standard. However, collisions in the random access (RA) channel of NB-IoT…
Abstract: User mobility prediction is widely researched. Many studies have used algorithms to predict where users will go based on their contexts and trajectories. Most studies target specific predictions. While successful cases are often reported,…
Abstract: Supremo is a cloud-assisted mobile image super-resolution (SR) system. We optimize state-of-the-art DNN to reduce inference latency since SR is compute-intensive. We also design a mobile-cloud cooperative execution pipeline with specialized data compression algorithms…
Abstract: Network slicing could transform the telecommunications ecosystem by offering new players in different markets tailored connectivity services based on their business strategies. Dynamic resource sharing is essential for efficiency, cost savings, and resource negotiation…
Abstract: This project derives closed-form expressions for significant statistical properties of the link signal-to-noise ratio (SNR) and separation distance in mobile ad hoc networks with Ornstein-Uhlenbeck (OU) mobility and Rayleigh fading. These systems depend on…
Abstract: Bike underflow or overflow causes bike-sharing system outages. Rebalancing station loads requires hiring workers. The complex rebalancing problem is partitioned temporally and spatially. The temporal domain has fixed-duration slices. NP-hard, we assign a worker…
Abstract: Indoor positioning systems have proliferated due to commercial interest in indoor localization services. Localization is limited by system requirements like site survey, user intervention, or specific hardware/software, despite extensive research. PYLON, an indoor path…
Abstract: Indoor localization allows retailers, warehouses, and libraries to sense and understand human behavior and provide personalized services. Existing indoor localization technologies are unable to identify different people, have severe object occlusion when multiple people…
