On the relevance of using interference and service differentiation routing in the internet-of-things (2013)
Presentation / Conference Contribution

Next generation sensor networks are predicted to be deployed in the Internet-of-the-Things (IoT) with a high level of heterogeneity. They will be using sensor motes which are equipped with different sensing and communication devices and tasked to del...

BOD-LEACH: Broadcasting over duty-cycled radio using LEACH clustering for delay/power efficient dissimilation in wireless sensor networks (2013)
Journal Article

Copyright © 2013 John Wiley & Sons, Ltd. Broadcasting delay-sensitive information over a duty-cycled wireless sensor network is considered, and a cluster-based protocol is proposed. The proposed protocol, namely Broadcast over Duty-Cycle and LEACH...

Duo-MAC: Energy and time constrained data delivery MAC protocol in wireless sensor networks (2013)
Presentation / Conference Contribution

We present Duo-MAC, an asynchronous cascading wake-up scheduled MAC protocol for heterogeneous traffic forwarding in low-power wireless networks. Duo-MAC deals with energy-delay minimization problem and copes with transmission latency encountered by...

Theoretical estimators and lower-bounds for receiver-to-receiver time synchronization in multi-hop wireless networks (2013)
Presentation / Conference Contribution

Maximum likelihood estimators (MLE) for time synchronization parameters of receiver-to-receiver protocols are derived. The MLE are first provided for a single-hop model, then generalized to a multi-hop model. The appropriate Cramer- Rao lower bounds...

Fault-tolerant implementation of a distributed MLE-based time synchronization protocol for wireless sensor networks (2013)
Presentation / Conference Contribution

This paper describes the implementation and evaluation of R4Syn protocol on MICAz platform and TinyOS operating system. The contribution is two folds. First, the implementation uses thorough maximum-likelihood estimators (MLE) in the joint offset/ske...

Fast distributed multi-hop relative time synchronization protocol and estimators for wireless sensor networks (2013)
Journal Article

The challenging problem of time synchronization in wireless sensor networks is considered in this paper, where a new distributed protocol is proposed for both local and multi-hop synchronization. The receiver-to-receiver paradigm is used, which has t... Read More about Fast distributed multi-hop relative time synchronization protocol and estimators for wireless sensor networks.

A study of wireless sensor networks for urban traffic monitoring: Applications and architectures (2013)
Presentation / Conference Contribution

With the constant increasing of vehicular traffic around the world, especially in urban areas, existing traffic management solutions become inefficient. This can be clearly seen in our life through persistent traffic jam and rising number of accident...

Synchronous contention-based MAC protocols for delay-sensitive wireless sensor networks: A review and taxonomy (2013)
Journal Article

Duty-cycling allows obtaining significant energy saving compared to full duty cycle (sleepless) random access MAC protocols. However, it may result in significant latency. In slotted duty-cycled medium access control (MAC) protocols, sensor nodes per...
