Guaranteeing the network lifetime in wireless sensor networks: A MAC layer approach
Energy is the most crucial but scarce resource in wireless sensor networks (WSNs). A wealth of MAC protocols are proposed only to prolong the network lifetime for energy-efficienc...

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...

A Software-Defined Radio System for Backscatter Sensor Networks
Backscatter radio is proposed for sensor networks. In that way, the transmitter for each sensor is simplified to a transistor connected to an antenna and therefore, the cost for ea...
