  • Fault-Tolerant Implementation of a Distributed MLE-based Time Synchronization Protocol for Wireless Sensor Networks 

    Djenouri, Djamel; Merabtine, Nassima; Mekahlia, Fatma Zohra; Doudou, Messaoud
    In : IEEE Wireless Communications and Networking Conference (WCNC), (IEEE Communications Society, Shangai, China, 2013-04)
    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/skew model, while all similar MLEbased estimators are merely evaluated ...
  • Power-aware QoS Geographical Routing for Wireless Sensor Networks - Implementation using Contiki 

    Djenouri, Djamel
    In : Rapports de recherche internes, (CERIST, Alger, 2010-05)
    This paper presents the design and implementation of a new geographical quality of service (QoS) routing for wireless sensor networks. The protocol is based on tra±c di®erentiation and provides customized QoS accord- ing to the tra±c requirement. For each packet, the protocol attempts to ful¯ll the required data-related ...
