A fundamental issue in the design of a wireless sensor network(WSN) is to devise mechanisms to make efficient use of its energy, and thus, extend its lifetime. Hardware and software solutions for WSNs must be energy-efficient in order to make better use of the limited energy available at sensor nodes. The goal of this tutorial is to discuss the role of energy in the design of WSNs. Most of the WSN protocols just try to save as much energy as possible in order to be suitable for this new kind of network. Others use the amount of the remaining energy at a node when performing a given task. However, an energy-efficient solution should probably consider cross-layer aspects. Due to the limited energy restriction, understanding the role of the energy in a WSN design is of paramount importance.

Introductory to intermediate
Raquel Mini holds a PhD in Computer Science from the Federal University of Minas Gerais (UFMG), Brazil. Since 1999 she is an Associate Professor of Computer Science at PUC Minas, Brazil. In her thesis work she studied the energy map construction for wireless sensor networks. Since 2001 she has been working on energy aware protocols for these networks. In the last 3 years, she has published several papers about wireless sensor networks in international conferences and journals. Her main research areas are sensor networks, distributed algorithms, and mobile computing.
Antonio Loureiro is an Associate Professor of Computer Science at the Federal University of Minas Gerais (UFMG), Brazil. Professor Loureiro holds a PhD in Computer Science from the University of British Columbia, Canada, 1995. His main research areas are sensor networks, mobile computing, computer networks and distributed systems. In the last 10 years he has published over 70 papers in international conferences and journals. Most of those papers were presented by Professor Loureiro who also has been the instructor of six tutorials in Brazilian conferences in the last five years. In August 2004, he presented a plenary session at the International Workshop on Telecommunications, and, in May 2005, he presented the tutorial entitled "Management of Wireless Sensor Networks" at the 9th IFIP/IEEE International Symposium on Integrated Network Management. Since 1996, when he became a faculty member at UFMG, Professor Loureiro has received six times the Undergraduate Teaching Excellence Award in Computer Science from the students at the Department of Computer Science. He was the TPC Chair for LANOMS 2001 (Latin American Network Operations and Management Symposium, sponsored by IEEE Communications Society) and for the 2005 ACM Workshop on Wireless Multimedia Networking and Performance Modeling.
