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...

Multiratecast in Wireless Fault Tolerant Sensor and Actuator Networks
We study the multicast problem in wireless sensor networks, where the source can send data to a fixed number of destinations (actuators) at a different rate (multiratecast). A typi...

Energy-Efficient Duty Cycle Assignment for Receiver-Based Convergecast in Wireless Sensor Networks
Duty cycling is often used to reduce the energy consumption caused by idle listening in Wireless Sensor Networks (WSNs). Most studies on WSN protocols define a common duty cycle va...

Maximization of Data Gathering in Clustered Wireless Sensor Networks
In this paper, we investigate the maximization of the amount of gathered data in a clustered wireless sensor network (WSN). The amount of gathered data is maximized by (1) choosing...
