Theoretical analysis of cooperative diversity in wireless sensor networks

Abstract

We propose here an analytical framework to quantify the impact of cooperative diversity on the energy consumption 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
