Network protocols in layered architectures have historically been obtained on an ad hoc
basis, and many of the recent cross-layer designs are also conducted through piecemeal …

This tutorial paper overviews recent developments in optimization-based approaches for
resource allocation problems in wireless systems. We begin by overviewing important …

Cellular networks have evolved to support high peak bitrates with low loss rates as observed
by the higher layers. However, applications and services running over cellular networks are …

This paper considers jointly optimal design of cross-layer congestion control, routing and
scheduling for ad hoc wireless networks. We first formulate the rate constraint and …

In a wireline network, nodes form links with only those nodes they are wired to, and the links
do not interfere with one another. In contrast, in a wireless network, signal transmissions are …

In this paper, we describe and analyze a joint scheduling, routing and congestion control
mechanism for wireless networks, that asymptotically guarantees stability of the buffers and …

Network utility maximization (NUM) problem formulations provide an important approach to
conduct network resource allocation and to view layering as optimization decomposition. In …

This paper focuses on congestion control over multi-hop, wireless networks. In a wireless
network, an important constraint that arises is that due to the MAC (Media Access Control) …

In this paper, we study cross-layer design for congestion control in multihop wireless
networks. In previous work, we have developed an optimal cross-layer congestion control …

We study efficient link scheduling for a multihop wireless network to maximize its throughput.
Efficient link scheduling can greatly reduce the interference effect of close-by transmissions …
