Enhancing the Reliability of Dense LoRaWAN Networks With Multi-User Receivers

Andreas Peter Burg, Joachim Tobias Tapparel, Mathieu Pierre Xhonneux

LoRaWAN is a low-power wireless technology that provides long-range connectivity to battery-powered Internet of Things (IoT) devices. To minimize the energy consumption of the IoT nodes, LoRaWAN networks use for the uplink a pure non-slotted ALOHA multiple ...

Successive Refinement to Caching for Dynamic Requests

Michael Christoph Gastpar, Pinar Sen

In the celebrated coded caching problem studied by Maddah-Ali and Niesen, the peak-traffic network load is to be reduced by first caching some information about contents into individual memories of end users during the off-peak hours and then upon user req ...

A Theory of Traffic Regulators for Deterministic Networks with Application to Interleaved Regulators

Jean-Yves Le Boudec

We define the minimal interleaved regulator, which generalizes the Urgency Based Shaper that was recently proposed by Specht and Samii as a simpler alternative to per-flow reshaping in deterministic networks with aggregate scheduling. With this regulator, ...

Adding flexibility to multi-tenant networks

Georgios Ioannidis

Cloud computing has been experiencing sharp development over the last years, leading to an increased demand for application migration to the cloud. Cloud providers, in an effort to attract more customers and earn their confidence, offer to tenants the illu ...

Empirical Performance Evaluation of Data Dissemination Mechanisms for Spot Applications

Jean-Yves Le Boudec, Alaeddine El Fawal, Adel Aziz

We evaluate, by measurements on a real testbed, the performance of networking services required for spot applications. We call a “spot application” an application for smartphones (such as “Ad-hoc Flash Sales”) that disseminates information in a local neigh ...

High Bandwidth CMOS Magnetic Sensors Based on the Miniaturized Circular Vertical Hall Device

Mirjana Banjevic

Hall-effect devices make up by far the largest part of all magnetic sensors on the market today. The main reason is compatibility of Hall devices with modern semiconductor technology. In particular, integrated Hall sensor micro-systems fabricated in low-co ...

In-Network Packet Scheduling and Rate Allocation: A Content Delivery Perspective

We investigate two important problems in media delivery via active network agents. First, we consider streaming multiple video assets over a shared backbone network through an intermediate proxy-server to a set of receiving clients. The proxy is located at ...

Multicast Parametric Sampling of 320 Gb/s Return-to-Zero Signal

Camille Sophie Brès

Technology for simultaneous demultiplexing of subrate tributaries is described and applied to 320-Gb/s return-tozero input. The parametric architecture is scalable with respect to processed input rate and relies on cascaded all-optical multicasting and sub ...

An Energy Detection Receiver Robust to Multi-User Interference for IEEE 802.15.4a Networks

Jean-Yves Le Boudec, Ruben Merz, Manuel Flury

Energy-detection receivers are appealing to IEEE 802.15.4a low data-rate networks because of their low complexity. With a reasonable energy consumption, these receivers can exploit the ranging capabilities and multipath resistance of impulse-radio UWB (IR- ...

On the throughput scaling of wireless relay networks

Patrick Thiran, Olivier Dousse

The throughput of wireless networks is known to scale poorly when the number of users grows. The rate at which an arbitrary pair of nodes can communicate must decrease to zero as the number of users tends to infinity, under various assumptions. One of them ...
