A Cross-Layer Design Approach to Enhance 802.15.4

The low-power communication in wireless sensor networks can be impacted by severe channel impairments. In this paper, to address this problem and achieve high network goodput, we propose that the medium access control protocol takes into consideration the ...

On the Throughput of Ad Hoc Networks using Connectivity Graphs

Christina Fragouli

In this paper we propose a set of necessary and sufficient conditions under which the throughput in an ad-hoc network can remain constant as the number of nodes n increases. Throughput refers to the minimum achievable rate between a source-destination pair ...

ASIC implementation of a MIMO-OFDM transceiver for 192 Mbps WLANs

Andreas Peter Burg

Next generation wireless local area networks (WLANs) such as the IEEE 802.11n standard are expected to rely on multiple antennas at both transmitter and receiver to increase throughput and link reliability. However, these improvements come at a significant ...

Improving TCP Performance in Ad Hoc Networks Using Signal Strength Based Link Management

Fabius Klemm

Mobility in ad hoc networks causes frequent link failures, which in turn causes packet losses. TCP attributes these packet losses to congestion. This incorrect inference results in frequent TCP re-transmission time-outs and therefore a degradation in TCP p ...

Scaling Laws for Energy-constrained Wireless Networks

Suhas Diggavi, Jasper Goseling

Although there has been much interest in scaling laws for wireless networks, most work has focussed on characterizing throughput and delay in power-constrained networks. Energy-constrained networks have not received much attention. Previous work on energy- ...

Denial-of-service resilience in peer-to-peer file sharing systems

Willy Zwaenepoel, Dan Mihai Dumitriu

Peer-to-peer (p2p) file sharing systems are characterized by highly replicated content distributed among nodes with enormous aggregate resources for storage and communication. These properties alone are not sufficient, however, to render p2p networks immun ...

Media Aware Routing in Large Scale Networks with Overlay

Pascal Frossard, Dan Jurca, Sofija Petrovic

This paper presents a new routing strategy, that selects the best network paths in an overlay network, in order to minimize the distortion perceived by the end user. We first propose a model that reports the video distortion as a function of the encoding r ...

A Bandwidth Sharing Approach to Improve Licensed Spectrum Utilization

Panagiotis Papadimitratos

The spectrum of deployed wireless cellular communication systems is found to be under-utilized, even though licensed spectrum is at a premium. To efficiently utilize the bandwidth left unused in a cellular system, which we denote as the primary system (PRI ...

Efficient processing of XPath queries with structured overlay networks

Karl Aberer, Manfred Hauswirth, Gleb Skobeltsyn

Non-trivial search predicates beyond mere equality are at the current focus of P2P research. Structured queries, as an important type of non-trivial search, have been studied extensively mainly for unstructured P2P systems so far. As unstructured P2P syste ...
