In Wireless Sensor Network (WSN) deployments, wireless sensor nodes should be strategically placed in order to maximize the sensed area while minimizing the number of nodes to be placed in the field. Moreover, wireless radio coverage distances should be taken into account in order to cover large areas. Wireless sensors may be located quite far from each other, allowing lower deployment costs, but it may increase the wireless sensor node power consumption due to the energy needed to reach large distances. Although many factors may affect the position of each wireless sensor node inside the WSN, there are two main ones: the radio coverage area, which allows the sensors to communicate, and, the sensing coverage area, which gives the sensing region. Both types of coverage areas could be affected by the field where the WSN is deployed, but different factors affect each type of coverage. The goal is to maximize the coverage percentage, while coverage holes should be minimized.
