This paper explores the feasibility of leveraging concepts from deep reinforcement learning (DRL) to enable dynamic resource management in Wi-Fi networks implementing distributed m…
Coverage and Rate Analysis of Super Wi-Fi Networks Using Stochastic Geometry
Neelakantan Nurani Krishnan, Gokul Sridharan, Ivan Seskar +1
Recent regulatory changes proposed by the Federal Communications Commission (FCC) permitting unlicensed use of television white space (TVWS) channels present new opportunities for…
Wireless Backhaul Node Placement for Small Cell Networks
Muhammad Nazmul Islam, Ashwin Sampath, Atul Maharshi +2
Small cells have been proposed as a vehicle for wireless networks to keep up with surging demand. Small cells come with a significant challenge of providing backhaul to transport d…
Uplink Linear Receivers for Multi-cell Multiuser MIMO with Pilot Contamination: Large System Analysis
Narayanan Krishnan, Roy D. Yates, Narayan B. Mandayam
Base stations with a large number of transmit antennas have the potential to serve a large number of users at high rates. However, the receiver processing in the uplink relies on c…
Cellular Systems with Many Antennas: Large System Analysis under Pilot Contamination
Narayanan Krishnan, Roy D. Yates, Narayan B. Mandayam
Base stations with a large number of transmit antennas have the potential to serve a large number of users simultaneously at higher rates. They also promise a lower power consumpti…
Implementation of Distributed Time Exchange Based Cooperative Forwarding
Muhammad Nazmul Islam, Shantharam Balasubramanian, Narayan B. Mandayam +2
In this paper, we design and implement time exchange (TE) based cooperative forwarding where nodes use transmission time slots as incentives for relaying. We focus on distributed j…
Optimal Resource Allocation and Relay Selection in Bandwidth Exchange Based Cooperative Forwarding
Muhammad Nazmul Islam, Narayan Mandayam, Sastry Kompella
In this paper, we investigate joint optimal relay selection and resource allocation under bandwidth exchange (BE) enabled incentivized cooperative forwarding in wireless networks.…
Analyzing Random Network Coding with Differential Equations and Differential Inclusions
Dan Zhang, Narayan B. Mandayam
We develop a framework based on differential equations (DE) and differential inclusions (DI) for analyzing Random Network Coding (RNC), as well as a nonlinear variant referred to a…
Opportunistic Communications in Fading Multiaccess Relay Channels
Lalitha Sankar, Yingbin Liang, Narayan Mandayam +1
The problem of optimal resource allocation is studied for ergodic fading orthogonal multiaccess relay channels (MARCs) in which the users (sources) communicate with a destination w…
Relay vs. User Cooperation in Time-Duplexed Multiaccess Networks
Lalitha Sankar, Gerhard Kramer, Narayan B. Mandayam
The performance of user-cooperation in a multi-access network is compared to that of using a wireless relay. Using the total transmit and processing power consumed at all nodes as…
On the Sum-Capacity of Degraded Gaussian Multiaccess Relay Channels
Lalitha Sankar, Narayan B. Mandayam, H. Vincent Poor
The sum-capacity is studied for a K-user degraded Gaussian multiaccess relay channel (MARC) where the multiaccess signal received at the destination from the K sources and relay is…
Opportunistic Communications in an Orthogonal Multiaccess Relay Channel
Lalitha Sankar, Yingbin Liang, H. Vincent Poor +1
The problem of resource allocation is studied for a two-user fading orthogonal multiaccess relay channel (MARC) where both users (sources) communicate with a destination in the pre…
A Utility-Based Approach to Power Control and Receiver Design in Wireless Data Networks
Farhad Meshkati, H. Vincent Poor, Stuart C. Schwartz +1
In this work, the cross-layer design problem of joint multiuser detection and power control is studied using a game-theoretic approach. The uplink of a direct-sequence code divisio…
A Non-Cooperative Power Control Game for Multi-Carrier CDMA Systems
Farhad Meshkati, Mung Chiang, Stuart C. Schwartz +2
In this work, a non-cooperative power control game for multi-carrier CDMA systems is proposed. In the proposed game, each user needs to decide how much power to transmit over each…
