Abstract: Communication in underground tunnels is one of the most important and challenging areas for engineering fraternity with multiplicity of constraints. Various factors such as frequency, tunnel size, cross-section shape and curvature, material used for construction, antenna position and polarization, all influence the path loss. With the availability of large number of factors which influences the path loss, the task of finding the optimal solution becomes complex. Constraint Satisfaction Programming has the potential of tackling wide range of search problems easily. The task of optimizing the path loss in tunnels can be modeled in CSP as that of searching the optimal set of parameters affecting the path loss.
