Comparative analysis of synchronization strategies in sensor network with misbehaving clocks

Clock synchronization protocols for sensor networks can be divided into hierarchical, cluster-structure-based, and fully-distributed. In this paper we compare hierarchical and fully-distributed strategies using a realistic clock model that allows to simulate different clock types and introduce faulty behaviour in selected nodes. This allows to focus the analysis on the resilience of different synchronization strategies in the presence of non-ideal clocks, for which results are provided.
