Figure 1. A possible second-order coloring scheme for a network with |V| = 13 nodes.
Figure 2. Illustration of the cost functions (4) and (7) versus x and y coordinates (target location); the minimum of the cost function is indicated by a white square
Figure 3. Simulation results for cooperative localization when L 0 is known: normalized root mean square error (NRMSE) versus k comparison for different N , when M = 50, σ = 0 dB, R = 6 m, B = 30 m, L 0 = 40 dB, γ = 3, d 0 = 1 m, M c = 500
Figure 5 illustrates the NRMSE versus k performance of the considered approaches for σ = 6 dB.
