On the Rate of Convergence of the Power-of-Two-Choices to its Mean-Field Limit
Lei Ying
This paper studies the rate of convergence of the power-of-two-choices, a celebrated randomized load balancing algorithm for many-server queueing systems, to its mean field limit.…
Distributed Admission Control without Knowledge of the Capacity Region
Juan Jose Jaramillo, Lei Ying
We consider the problem of distributed admission control without knowledge of the capacity region in single-hop wireless networks, for flows that require a pre-specified bandwidth…
Distributed Power Control and Coding-Modulation Adaptation in Wireless Networks using Annealed Gibbs Sampling
Shan Zhou, Xinzhou Wu, Lei Ying
In wireless networks, the transmission rate of a link is determined by received signal strength, interference from simultaneous transmissions, and available coding-modulation schem…
Scheduling for Optimal Rate Allocation in Ad Hoc Networks With Heterogeneous Delay Constraints
Juan Jose Jaramillo, R. Srikant, Lei Ying
This paper studies the problem of scheduling in single-hop wireless networks with real-time traffic, where every packet arrival has an associated deadline and a minimum fraction of…
Queue-Architecture and Stability Analysis in Cooperative Relay Networks
Jubin Jose, Sriram Vishwanath
An abstraction of the physical layer coding using bit pipes that are coupled through data-rates is insufficient to capture notions such as node cooperation in cooperative relay net…
The Asymptotic Behavior of Minimum Buffer Size Requirements in Large P2P Streaming Networks
Lei Ying, R. Srikant, Srinivas Shakkottai
The growth of real-time content streaming over the Internet has resulted in the use of peer-to-peer (P2P) approaches for scalable content delivery. In such P2P streaming systems, e…
On Delay Constrained Multicast Capacity of Large-Scale Mobile Ad-Hoc Networks
Shan Zhou, Lei Ying
This paper studies the delay constrained multicast capacity of large scale mobile ad hoc networks (MANETs). We consider a MANET consists of multicast sessions. Each multicast…
Throughput-Optimal Opportunistic Scheduling in the Presence of Flow-Level Dynamics
Shihuan Liu, Lei Ying, R. Srikant
We consider multiuser scheduling in wireless networks with channel variations and flow-level dynamics. Recently, it has been shown that the MaxWeight algorithm, which is throughput…
Optimal Delay-Throughput Trade-offs in Mobile Ad-Hoc Networks: Hybrid Random Walk and One-Dimensional Mobility Models
Lei Ying, R. Srikant
Optimal delay-throughput trade-offs for two-dimensional i.i.d mobility models have been established in [23], where we showed that the optimal trade-offs can be achieved using rate-…
Coding Improves the Optimal Delay-Throughput Trade-offs in Mobile Ad-Hoc Networks: Two-Dimensional I.I.D. Mobility Models
Lei Ying, Sichao Yang, R. Srikant
In this paper, we investigate the delay-throughput trade-offs in mobile ad-hoc networks under two-dimensional i.i.d. mobility models. We consider two mobility time-scales: (i) Fast…
