Integration and scalable coordination of many sensor nodes in a Wireless Sensor Network (WSN) is among this century challenges. To provide energy-efficient communication protocol and coordination algorithm for topology maintenance, this requires employing global optimization of communication and sensing. In designing a sensor network, there are certain QoS parameters that need to be considered, such as density, accuracy, latency and lifetime. The authors consider density as the most important parameter to fulfill network coverage with energy saving.
