Game-Theoretic Framework for Private Data Sharing in Vehicular Networks
Yousef AlSaqabi, Yinan Zhou, Faisal Nawab +1
We present a novel game-theoretic framework designed to enhance privacy and scalability in decentralized vehicular data collection systems. The proposed hybrid architecture compris…
Partitioning and Deployment of Deep Neural Networks on Edge Clusters
Arjun Parthasarathy, Bhaskar Krishnamachari
Edge inference has become more widespread, as its diverse applications range from retail to wearable technology. Clusters of networked resource-constrained edge devices are becomin…
SEIFER: Scalable Edge Inference for Deep Neural Networks
Arjun Parthasarathy, Bhaskar Krishnamachari

Closed-Form Whittle's Index-Enabled Random Access for Timely Status Update
Jingzhou Sun, Zhiyuan Jiang, Bhaskar Krishnamachari +2
We consider a star-topology wireless network for status update where a central node collects status data from a large number of distributed machine-type terminals that share a wire…
Heat-Diffusion: Pareto Optimal Dynamic Routing for Time-Varying Wireless Networks
Reza Banirazi, Edmond Jonckheere, Bhaskar Krishnamachari
A dynamic routing policy, referred to as Heat-Diffusion (HD), is developed for multihop uniclass wireless networks subject to random traffic, time-varying topology and inter-channe…
Deep Reinforcement Learning for Dynamic Multichannel Access in Wireless Networks
Shangxing Wang, Hanpeng Liu, Pedro Henrique Gomes +1
We consider a dynamic multichannel access problem, where multiple correlated channels follow an unknown joint Markov model. A user at each time slot selects a channel to transmit d…
A Unifying Bayesian Optimization Framework for Radio Frequency Localization
Nachikethas A. Jagadeesan, Bhaskar Krishnamachari
We consider the problem of estimating an RF-device's location based on observations, such as received signal strength, from a set of transmitters with known locations. We survey th…
Empirical Evaluation of the Heat-Diffusion Collection Protocol for Wireless Sensor Networks
Pradipta Ghosh, He Ren, Reza Banirazi +2
Heat-Diffusion (HD) routing is our recently-developed queue-aware routing policy for multi-hop wireless networks inspired by Thermodynamics. In the prior theoretical studies, we ha…
Robotic Message Ferrying for Wireless Networks using Coarse-Grained Backpressure Control
Shangxing Wang, Andrea Gasparri, Bhaskar Krishnamachari
We formulate the problem of robots ferrying messages between statically-placed source and sink pairs that they can communicate with wirelessly. We first analyze the capacity region…
LORD: Leader-based framework for Resource Discovery in Mobile Device Clouds
Seyed Mohammad Asghari, Yi-Hsuan Kao, Mohammad Hassan Lotfi +4
We provide a novel solution for Resource Discovery (RD) in mobile device clouds consisting of selfish nodes. Mobile device clouds (MDCs) refer to cooperative arrangement of communi…
Multiflow Transmission in Delay Constrained Cooperative Wireless Networks
Marjan Baghaie, Dorit S. Hochbaum, Bhaskar Krishnamachari
This paper considers the problem of energy-efficient transmission in multi-flow multihop cooperative wireless networks. Although the performance gains of cooperative approaches are…
Backpressure with Adaptive Redundancy (BWAR)
Majed Alresaini, Maheswaran Sathiamoorthy, Bhaskar Krishnamachari +1
Backpressure scheduling and routing, in which packets are preferentially transmitted over links with high queue differentials, offers the promise of throughput-optimal operation fo…
Optimality of Myopic Sensing in Multi-Channel Opportunistic Access
Sahand H. A. Ahmad, Mingyan Liu, Tara Javidi +2
We consider opportunistic communications over multiple channels where the state ("good" or "bad") of each channel evolves as independent and identically distributed Markov processe…
Structure and Optimality of Myopic Policy in Opportunistic Access with Noisy Observations
Qing Zhao, Bhaskar Krishnamachari
A restless multi-armed bandit problem that arises in multichannel opportunistic communications is considered, where channels are modeled as independent and identical Gilbert-Elliot…
