3.2 Computation of Node Location

In this section, the location of the Target Node (TN) is estimated considering that measurement errors can be present, for every pair of Detecting Nodes (DN) and Target Nodes (Fig. 2).

Fig. 2 a In an ideal situation. b With measurement errors. Dark circle indicates the nodes (D1, D2, D3, T0). a is a situation which is ideal since propagation of signal circles cross at one point representing a unique location. b is a situation which is practical and has errors in the signal distances, hence the circles do not cross at one single point; in fact, they might not be able to cross at any point. Hence this scenario represents a situation where we may not be able to obtain a location with acceptable accuracy
