Asymptotic Characterization of Log-Likelihood Maximization Based Algorithms and Applications
The asymptotic distribution of estimates that are based on a sub-optimal search for the maximum of the log-likelihood function is considered. In particular, estimation schemes that...

Improving WSN Simulation and Analysis Accuracy Using Two-Tier Channel Models
— Accurate simulation and analysis of wireless protocols and systems is inherently dependent on an accurate model of the underlying channel. In this paper, we show that residual ...

Stability analysis of the consensus-based distributed LMS algorithm
We deal with consensus-based online estimation and tracking of (non-) stationary signals using ad hoc wireless sensor networks (WSNs). A distributed (D-) least-mean square (LMS) l...

On the Reliability of Large-Scale Distributed Systems A Topological View
In large-scale, self-organized and distributed systems, such as peer-to-peer (P2P) overlays and wireless sensor networks (WSN), a small proportion of nodes are likely to be more c...
