An information fidelity criterion for image quality assessment using natural scene statistics
TLDR
We propose a novel information fidelity criterion for image QA based on natural scene statistics that outperforms current methods in our testing. Expand

Transmission capacity of wireless ad hoc networks with outage constraints
TLDR
In this paper, upper and lower bounds on the transmission capacity of spread-spectrum (SS) wireless ad hoc networks, which incorporate traditional modulation types (no spreading) as a special case, are derived. Expand

Service capacity of peer to peer networks
TLDR
We study the 'service capacity' of peer to peer (P2P) file sharing applications in steady state and show how the average delay seen by peers would scale in the offered load. Expand

Distributed $\alpha$ -Optimal User Association and Cell Load Balancing in Wireless Networks
TLDR
In this paper, we develop a framework for user association in infrastructure-based wireless networks, specifically focused on flow-level cell load balancing under spatially inhomogeneous traffic distributions. Expand

Video Quality Assessment on Mobile Devices: Subjective, Behavioral and Objective Studies
TLDR
We introduce a new video quality database that models video distortions in heavily-trafficked wireless networks and that contains measurements of human subjective impressions of the quality of videos. Expand

Capacity of ad hoc wireless networks with infrastructure support
TLDR
We determine the asymptotic scaling for the per user throughput in a large hybrid ad hoc network, i.e., a network with both ad hoc nodes, which communicate with each other via shared wireless links of capacity W bits/s, and infrastructure nodes which in addition are interconnected via high capacity links.

Joint Scheduling of URLLC and eMBB Traffic in 5G Wireless Networks
TLDR
A framework and algorithms for joint scheduling of URLLC (low latency) and eMBB (broadband) traffic in emerging 5G systems. Expand

Transmission Capacity of Wireless Ad Hoc Networks With Successive Interference Cancellation
TLDR
We study the improvement in TC obtainable with successive interference cancellation (SIC), an important receiver technique that has been shown to achieve the capacity of several classes of multiuser channels, but has not been carefully evaluated in the context of ad hoc wireless networks. Expand

Stability and performance analysis of networks supporting elastic services
TLDR
We consider the stability and performance of a model for networks supporting services that adapt their transmission to the available bandwidth. Expand

Dynamic association for load balancing and interference avoidance in multi-cell networks
TLDR
We formulate the proportional fair association problem P-association in multi-cell networks as a network-wide utility maximization problem and propose optimal offline and practical online algorithms to solve this. Expand
