Abstract: Many realistic mobile social networks have evolving bipartite graphs, in which dynamically added elements are divided into two entities and connected by links between them, such as users and items in recommendation networks, authors…
Abstract: Geo-indistinguishability allows users to submit obfuscated locations to Location-Based Service providers and still use services. Inference attacks can compromise these mechanisms. Long-term observation attacks can reveal a user’s real locations if an attacker knows…
Abstract: Fog computing, which integrates mobile-edge and cloud resources, has emerged due to the widespread adoption of Internet-of-Things (IoT) applications. Due to resource constraints, IoT mobility, heterogeneity, network hierarchy, and stochastic behaviors, scheduling application tasks…
Abstract: 3GPP is working hard to achieve 5G sub-millisecond latencies. If exogenous transport layer delays are ignored, such efforts may fail. To avoid wasting wireless resources, Radio Access Networks (RANs) are deployed with large buffers….
Abstract: This project optimizes cellular network underlay multicast device-to-device (D2MD) energy efficiency. We maximize global network and user energy efficiency considering fairness factors like maximum power and minimum rate constraints. We use a canonical mixed-integer…
Abstract: In underwater acoustic networks (UWANs), long propagation delay degrades throughput, making medium access control (MAC) protocol design critical. This paper develops a deep reinforcement learning (DRL)-based MAC protocol for UWANs, delayed-reward deep-reinforcement learning multiple…
Abstract: Wireless network performance depends on user association. We study the user association problem in densely deployed full-duplex cellular networks with highly variable transmit powers and topologies (e.g., heterogeneous networks). Decoupled UL-DL (DUDe) association allows…
Abstract: Dense deployment of small cells on different frequency bands using multiple technologies can help address the imminent thousand-fold traffic increase. Heterogeneous network (HetNet) architecture efficiently offloads traffic between tiers and technologies. Over the years,…
Abstract: Data collection, sensing coverage, and device control depend on sweep coverage. This paper addresses the cooperative sweep coverage problem with multiple mobile sensors to periodically cover all surveillance region PoIs. In contrast to traditional…
Abstract: Telco technologies have grown rapidly from 2G to 5G. Telco operators manage, operate, and optimize networks with precise outdoor localization. Telco operators use MR data to localize outdoor mobile devices, unlike GPS. Telco localization…
Abstract: Due to their scalability, affordability, and prevalence of Bluetooth-enabled devices, Bluetooth low energy (BLE) beacon networks are a common infrastructure for IoT and smart city applications. BLE beacon networks’ short battery life increases maintenance…
Abstract: This project addresses the coexistence problem between multiple wireless body area networks (WBANs), where co-channel interference can occur if channels are not allocated properly, reducing energy efficiency and packet transmission reliability. We solve the…
