The PhD program has commenced on December 2012 for three years where the graduation is expected to be in 2016. The main theme of this work is to improve the energy efficiency of Wireless Sensor Networks (WSNs). The thesis has multiple approaches tackling the main sources of energy consumption in WSNs. These approaches are classified into three main roots: ”‘Energy-cheap”’ data aggregation, Hard...

This document is a tutorial version of [1], its main purpose is to provide enough information and tools to generate link layer models for wireless sensor networks (WSN), namely the packet reception rate (PRR) as a function of distance. It also provides a basic understanding of simple concepts in wireless communication (used in the model) for people who does not feel comfortable with the physica...

Wireless Sensor Networks (WSNs) have many sensor nodes having restricted battery, which transmit sensed data to the Base Station that requires high energy consumption. Numerous routing protocols have now been proposed in this regard getting energy efficiency in heterogeneous situations. Though, each protocol is inappropriate for heterogeneous WSNs. Efficiency of WSNs declines as varying the het...
