In recent years, to ensure reliable monitoring and analysis of unknown and untested environments, practitioners have started using Wireless Sensor Networks (WSNs), 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 end 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 presentation, we describe optimal placement of sensors techniques that maximize the network lifetime under the constraint that connectivity is preserved.
