Abstract-- We propose here an analytical framework to quan-
tify the impact of cooperative diversity on the energy con-
sumption and lifetime of sensor networks. It is well accepted
that cooperative diversity increases energy efficiency in fading
environments. However, previous works have not analyzed, from
a theoretical perspective, these benefits in a network setting.
This paper presents a theoretical framework to model routing
behavior and cooperative relay selection, using this information
to predict the lifetime and energy consumption of the network.
I. INTRODUCTION
Wireless sensor networks (WSNs) refer to a broad class of
wireless networks consisting of small, inexpensive and energy
limited devices [1]. In these networks, sensors have the respon-
