Fast mean square convergence of consensus algorithms in WSNs with random topologies
The average consensus in wireless sensor networks is achieved under assumptions of symmetric or balanced topology at every time instant. However, communication and/or node failure...

Reaching consensus in asynchronous WSNs: Algebraic approach
Many models of wireless sensor networks (WSNs) assume a perfect synchronization along the graph of such network as a simplifying assumption. In our contribution we base our invest...

Secure Data Collection in Wireless Sensor Networks Using Randomized Dispersive Routes
—Compromised-node and denial-of-service are two key attacks in wireless sensor networks (WSNs). In this paper, we study routing mechanisms that circumvent (bypass) black holes fo...
