A method for configuring a wireless network of Unattended Ground Sensors, consisting of interconnected nodes each including a sensing module, an own power supply, computing means, communication means, means for saving an operating configuration and means for managing its operation according to this configuration stored in memory, characterized in that it includes the following steps: 1 Defining (step 12) performance criteria forming constraints, with associated threshold values (CPC*), and at least one performance criterion to be optimized, for at least one zone (Z i) to be equipped with nodes, each performance criterion being defined by a model 2 Defining (step 10) for said or each zone (Z i): a. Characteristics (d) of the zone b. Characteristics (E j) of the sensors in the zone 3 Allocating (step 10) to said or each zone (Z i) to be equipped, a number of nodes 4 Applying (step 22) an optimization process per zone on said or each zone (Z i), the optimization process per zone applying the following steps: a. Determining (step 50) the position of the nodes in the zone if it exists for meeting a predetermined optimization criterion; b. Determining (steps 72, 80, 86) an operating point if it exists, characterizing the behavior of the network of sensors in the zone, and c. Determining (steps 72, 80, 86) the configuration (Conf) of the network of sensors in the zone if it exists, defining the configuration parameters of the network of sensors, and d. Determining (steps 66, 88) the possible need of using more nodes or revising the performance criteria (CPC* and CPO) defined in step 1, 5 Increasing the number of nodes or modifying the performance criteria (CPC* and CPO) defined in said or each zone where the performance criteria are not met and reproducing in these zones the optimization process per zone with the new number of nodes or the new performance criteria (CPC* and CPO), and 6 Applying the configuration determined at each node in said or each zone. 1 Defining (step 12) performance criteria forming constraints, with associated threshold values (CPC*), and at least one performance criterion to be optimized, for at least one zone (Z i) to be equipped with nodes, each performance criterion being defined by a model 2 Defining (step 10) for said or each zone (Z i): a.
