Opportunistic transmission scheduling with resource-sharing constraints in wireless networks
We present an "opportunistic" transmission scheduling policy that exploits time-varying channel conditions and maximizes the system performance stochastically under a certain resource allocationExpand

A tutorial on cross-layer optimization in wireless networks
This tutorial paper overviews recent developments in optimization-based approaches for resource allocation problems in wireless systems. We begin by overviewing important results in the area ofExpand

A framework for opportunistic scheduling in wireless networks
Abstract We present a method, called opportunistic scheduling, for exploiting the time-varying nature of the radio environment to increase the overall performance of the system under certain qualityExpand

A utility-based power-control scheme in wireless cellular systems
Distributed power-control algorithms for systems with hard signal-to-interference ratio (SIR) constraints may diverge when infeasibility arises. In this paper, we present a power-control frameworkExpand

LITEWORP: a lightweight countermeasure for the wormhole attack in multihop wireless networks
In multihop wireless systems, such as ad-hoc and sensor networks, the need for cooperation among nodes to relay each other's packets exposes them to a wide range of security attacks. A particularlyExpand

Update or wait: How to keep your data fresh
In this work we study how to manage the freshness of status updates sent from a source to a remote monitor via a network server. A proper metric of data freshness at the monitor is theExpand

On the complexity of scheduling in wireless networks
We consider the problem of throughput-optimal scheduling in wireless networks subject to interference constraints. We model the interference using a family of K -hop interference models. We define aExpand

Non-convex optimization and rate control for multi-class services in the Internet
In this paper, we investigate the problem of distributively allocating transmission data rates to users in the Internet. We allow users to have concave as well as sigmoidal utility functions asExpand

A central-limit-theorem-based approach for analyzing queue behavior in high-speed networks
In this paper, we study P(/spl Qscr/>x), the tail of the steady-state queue length distribution at a high-speed multiplexer. In particular, we focus on the case when the aggregate traffic to theExpand
