Modern protocols for wireless sensor networks efficiently support multi-hop upward traffic from many sensors to a collection point, a key functionality enabling monitoring applications. However, the ever-evolving scenarios involving low-power wireless devices increasingly require support also for downward traffic, e.g., enabling a controller to iss...

LoRa technology is an increasingly popular option for applications that can exploit its low power and long range capabilities. While most efforts to date have studied its characteristics for smart city environments, we take LoRa outside the city limits, exploring how the environment affects its core communication properties. Specifically, we offer...

RPL, the IPv6 Routing Protocol for low-power and lossy networks, is considered the de facto routing protocol for the Internet of Things (IoT). Since its standardization, RPL has contributed to the advancement of communications in the world of tiny, embedded networking devices by providing, along with other standards, a baseline architecture for IoT...

De nouveaux protocoles ont été standardisés afin d'intégrer les réseaux de capteurs sans fil (WSN) dans l'Internet. Parmi eux, RPL pour la couche routage et IEEE 802.15.4 pour la couche MAC. L'objectif de cette thèse est d'améliorer ces protocoles en prenant compte des contraintes énergétiques des dispositifs du WSN. Tout d'abord, nous avons conçu...

RPL, the IPv6 Routing Protocol for Low-Power and Lossy Networks, supports both upward and downward traffic. The latter is fundamental for actuation, for queries, and for any bidirectional protocol such as TCP, yet its support is compromised by memory limitation in the nodes. In RPL storing mode, nodes store routing entries for each destination in t...

Energy is a very scarce resource in Wireless Sensor Networks. While most of the current proposals focus on minimizing the global energy consumption, we aim here at designing an energy-balancing routing protocol that maximizes the lifetime of the most constraint nodes. To improve the network lifetime, each node should consume the same (minimal) quan...

Conference Paper
Full-text available
IEEE 802.15.4 represents a widely used MAC-layer standard for Wireless Sensor Networks. In multihop topologies, the protocol exploits a cluster-tree and organizes the transmissions by alternating sleeping and active periods in a superframe delimited by beacons. In this paper, we propose a new Contention Broadcast Only Period to limit beacon collisi...

The devices composing Wireless Sensor Networks (WSN) are very limited in terms of memory, processing power and battery. We need efficient routing algorithms to ensure a long lifetime of the WSN. However, many solutions focus on minimizing the average energy consumption of all the nodes. Since the lifetime is rather given by the death of the first n...
Conference Paper
Full-text available
The IPv6 Routing Protocol for Low-Power and Lossy Networks (RPL) is one of the emerging routing standards for multihop Wireless Sensor Networks (WSN). RPL is based on the construction of a Destination-Oriented Directed Acyclic Graph (DODAG), which offers a loop-free topology to route data packets. While several routing metrics have been proposed in...

Call for Papers 1st Workshop on Emerging Technologies and Trends in Engineering Low-Power Networks (NewNets - co-located with IEEE WF-IoT) April 15, 2019 - Limerick, Ireland Submission deadline: Thursday, January 17, 2019 https://newnets2019.github.io/ ---------------------------------------------------------------------------- AIMS AND SCOPE A founding pillar of the IoT concept is the availability of low-cost low-power devices with wireless technologies providing both sensing and actuation. In the past decade, the research community have produced proven solutions to build low-power mesh networks. Traditionally, the focus has been on short-range radio communication (e.g., ZigBee, Bluetooth, ZWave). An appealing alternative that have gained momentum in the IoT landscape is to equip the nodes with long-range radio modules. As a result, long-range radio communication technologies (e.g., SigFox, LoRa, and 802.15.4g) are considered as candidate technologies for many low-power wide area network (LPWAN) applications, especially those that require extended coverage such as citywide sensing, environmental monitoring, or remote infrastructure monitoring. The 1st Workshop on Emerging Technologies and Trends in Engineering Low-Power Networks (NewNets) brings together researchers and practitioners working in the field of IoT from both academia and industry, to discuss and explore short- and long-range solutions, the tradeoffs between these two paradigms, as well as how they can be used in synergy. In order to push the state of the art, several points need to be addressed: new features for the long-range technologies (i.e., over-the-air updates, roaming), radio resource management, regulations and policies on spectrum usage and sharing, business case analysis that are more well suited for certain vertical markets. We invite researchers and practitioners from academia and industry to submit papers. We particularly encourage submissions that focus on one of the following: - protocol design; - hardware platform design; - modelling and analysis of low-power short or/and long-range communication; - reliability, adaptability, and dependability of short and long-range communication solutions; - new features for the long-range technologies (i.e., over-the-air updates, roaming); - radio resource management; - deployment experiences, case studies, and lessons learned; - evaluation and testbeds; - regulations and policies on spectrum usage and sharing; - business case analysis that are more well suited for certain vertical markets. SUBMISSION AND FORMATTING Submitted papers must contain between 4 and 6 single spaced U.S. letter pages, including all figures, tables, and references. All submissions must be written in English. Submissions should be formatted using the standard IEEE template for Microsoft Word or LaTeX. Authors should indicate their names and affiliations on the first page of the paper. All submissions must be in PDF format and render without error using standard viewers (e.g., Acrobat Reader). Submitted papers must differ significantly in content from previously published papers and must not be currently under review for any other publication. Paper submission deadline: Thursday, January 17, 2019 (11:59:59PM EST) Notification to authors: Sunday, February 17, 2019 Camera-ready submission deadline: Wednesday, February 27, 2019 ORGANIZERS TPC Co-chairs: Oana Iova (INSA Lyon, France) Ramona Marfievici (Nimbus Research Center, Ireland) Usman Raza (Toshiba Research Europe Limited, UK) TPC MEMBERS Matteo Ceriotti (University of Duisburg-Essen, Germany) Victor Cionca (Cork Institute of Technology, Ireland) Evgeny Khorov (IITP RAS and NRU HSE, Russia) Gaia Maselli (University of Rome La Sapienza, Italy) Konstantin Mikhaylov (University of Oulu, Finland) Georgios Papadopoulus (IMT Atlantique, France) Rajeev Pyiare (Fondazione Bruno Kessler, Italy) Vijay Rao (Delft University of Technology, The Netherlands) Felix Sutton (ABB Corporate Research, Switzerland) Eirini Eleni Tsiropoulou (University of New Mexico, USA) Ambuj Varshney (Uppsala University, Sweden)
