In recent years, to ensure reliable monitoring and analysis of unknown and untested environments, practitioners have started using Wireless Sensor Networks (WSNs), i.e., collections of tiny disposable, low-power devices, equipped with programmable computing, multiple-parameter-sensing, and wireless communication capacity, able to measure ambient conditions to detect some objects located or events happening around. Hundreds to thousands of unattended sensors forming a WSN communicate with each other and with a central base-station that, in its turn, communicates with the user(s). When designing a WSN, it is critically important to place the sensors and set up routing protocols in such a way as to maintain connectivity and maximize the network lifetime. In this paper, we describe techniques that maximize the network lifetime under the constraint that connectivity is preserved.
