Frame Preamble MAC for Multihop Wireless Sensor Networks: Design and Implementation
1 November 2008, by Abdelmalik Bachir, Andrzej Duda, Martin HeusseMAC protocols based on preamble sampling techniques offer significant energy savings for low data- rate multihop wireless sensor networks by efficiently reducing idle listening in lightly loaded networks. However, without any particular optimization, preamble sampling protocols still consume large amounts of energy due to the overhead induced by the long preamble transmitted prior data frames. To reduce the overhead induced by the use a full length preamble, many improvements have been (...)

Optimizing Routing and Channel Access Protocols to Extend the Lifetime of Wireless Sensor Networks / Allongement de la durée de vie des réseaux sans fil de capteurs par l’optimisation des protocoles de routage et d’accès au canal
29 January 2007, by Abdelmalik BachirExtending the lifetime of a sensor network requires optimizations at two complementary scopes: local and global. At the scope front, each node should optimize its own energy consumption to maximize its life span. At the global scope, nodes should cooperate to optimize the global usage of energy resources. In this thesis, we have addressed both problems through the optimization of communication protocols. Our contribution mainly concerns MAC and Routing protocols. At the MAC layer, we (...)

Energy-aware Georouting with Guaranteed Delivery in Wireless Sensor Networks with Obstacles
1 September 2009, by Bogdan Pavkovicdoi: 10.1007/s10776-009-0105-1
We propose, EtE, a novel end-to-end localized routing protocol for wireless sensor networks that is energy-efficient and guarantees delivery. To forward a packet, a node s in graph G computes the cost of the energy weighted shortest path between s and each of its neighbors in the forward direction towards the destination which minimizes the ratio of the cost of the shortest path to the progress (reduction in distance towards the destination). It then sends (...) -
ANR IRIS 2012-2014
1 January 2012, by Franck RousseauIris website
IRIS proposes to explore how Smart Objects can be interconnected and viewed as interoperable IP based end-hosts on the Internet thus making the Future Internet of Smart Objects happen and enabling the emergence of novel and exciting applications. We are not alone in seeing the vision of IP-based smart objects, as evidenced by the IPSO Alliance, IETF standards (6LoWPAN, ROLL, CoAP), and recent start-ups/companies that follow the same track. However, even though the IETF (...) -

EU ICT CALIPSO 2011-2014
1 September 2011, by Franck RousseauCalipso website
CALIPSO builds Internet Protocol (IP) connected smart object networks, but with novel methods to attain very low power consumption, thereby providing both interoperability and long lifetimes. CALIPSO leans on the significant body of work on sensor networks to integrate radio duty cycling and data-centric mechanisms into the IPv6 stack, something that existing work has not previously done. CALIPSO works at three layers: the network, the routing, and the application layer. We (...)
