A Distributed Wake-Up Scheduling for Opportunistic Forwarding in Wireless Sensor Networks
In wireless sensor networks (WSNs), sensor nodes are typically subjected to energy constraints and often prone to topology changes. While duty cycling has been widely used for ener...

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...
