Titre : Secure time synchronization in wireless sensor network Type de document : texte imprimé Auteurs : Lamis Lellouche ; Rayane Derbal ; Habib Aissaoua, Directeur de thèse Editeur : Setif:UFA Année de publication : 2023 Importance : 1 vol. (74 f.) Format : 29 cm Langues : Français (fre) Catégories : Thèses & Mémoires:Informatique Mots-clés : Security Clock synchronization outliers detection WCCS wireless sensor
networkRésumé : Time synchronization is crucial for wireless sensor networks (WSNs) and secure
time synchronization is a key requirement for many applications running on these networks.
In fact, in the presence of malicious intruders, it is highly probable that the
majority of current time synchronization protocols in WSNs will experience degradation
or complete breakdown. In this thesis, we focus on how to defend the Weighted
Consensus Clock Synchronization (WCCS) protocol in WSNs under malicious nodes.
First, we study the impact of malicious nodes on WCCS. Then, we propose a new
scheme to secure WCCS using an outlier detection method. In order to evaluate our
proposed algorithm, we use Castalia simulator. The simulation results show that our
proposal is very robust against malicious attacks and quite accurate as all malicious
nodes are exactly identified by all adjacent nodes.Côte titre : MAI/0748 En ligne : https://drive.google.com/file/d/1Usm0NcLizAJ5tflZakSxgpDZM6VMC3jT/view?usp=drive [...] Format de la ressource électronique : Secure time synchronization in wireless sensor network [texte imprimé] / Lamis Lellouche ; Rayane Derbal ; Habib Aissaoua, Directeur de thèse . - [S.l.] : Setif:UFA, 2023 . - 1 vol.
