Aiming to maximum the lifetime of battery-powered sensors, many research efforts
concentrate on sleep schedule that provides duty cycles for nodes to cut down energy …

To achieve the purpose of energy conservation, various sleep scheduling approaches, such
as duty cycle, are applied in wireless sensor networks (WSN). However, the duty-cycle …

In this paper, we discuss how cooperative transmission (CT) can provide better services
and/or lower the initial cost compared to non-CT in wireless sensor networks. To see the …

Wireless sensor network is the network of tiny size of sensor nodes. These sensor nodes
have sensing capability and transmit the sensed information to sink node. If the energy of …

We consider wireless sensor networks (WSN) powered by energy harvested from the
environment, which is assumed to be sporadic and random in nature. Wireless nodes in …

The use of cooperative communication technology in energy harvesting sensor networks is
one of the most viable solutions to overcome the power limitations of the battery-powerd …

Energy efficiency is one of the major goals for achieving green wireless communications.
