In a multi-hop wireless sensor network (WSN), the nodes that are one hop away from the
Sink die first and cause an" energy hole," because they must forward the traffic from the rest …

Cooperative communication (CC) allows multiple nodes to simultaneously transmit the same
packet to the receiver so that the combined signal at the receiver can be correctly decoded …

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 …

An opportunistic large array (OLA) is a group of simple, inexpensive relays or forwarding
nodes that operate without any mutual coordination, but naturally fire together in response to …

Energy-constrained wireless sensor networks require robust and energy-efficient wireless
communication protocols to minimize the energy consumption as much as possible …

Cooperative communication (CC) allows multiple nodes to simultaneously transmit the same
packet to the receiver so that the combined signal at the receiver can be correctly decoded …

Cooperative transmission technique is now widely considered as a promising approach to
combat fading and achieve energy efficiency in wireless networks. In this paper we focus on …

Energy hole is an inherent problem in wireless sensor networks, which results from heavier
traffic loads of nodes nearer to the sink, and leads to significant network lifetime reduction …

In this letter, we propose a new metric for energy-efficient cooperative transmission in
wireless sensor networks (WSN) where the circuit energy consumption is taken into …

The design of Wireless Sensor Networks (WSNs) should focus on energy efficiency since
wireless sensor nodes work on limited batteries, which are difficult or impossible to replace …
