Performance evaluation of MAC transmission power control in wireless sensor networks
In this paper we provide a method to analytically compute the energy saving provided by the use of transmission power control (TPC) at the MAC layer in wireless sensor networks (W...

Opportunistic real-time routing in multi-hop wireless sensor networks
Wireless sensor networks (WSNs) are subject to significant resource constraints. Particularly, routing protocols for lowrate WSNs suffer from maintaining routing metrics and sta...

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...
