In this chapter, we have presented a different approach to solve the problems of RWA in wavelength-routed survivable optical networks. This approach solves the problems of RWA jointly by formulating the problem as a linear programming problem. Although this approach increases the number of variables required to formulate the problem, it ensures obtaining the optimum solution. The study also found that many network optimization problems can be solved using an LP solvers. However, more research is needed to investigate the problem and find out ways to ensure integer solutions using LP solver when an optimum integer solution is feasible. The following problem formulation has been performed:

Ad hoc networks are an area of telecommunications that has grown in popularity due to its wide applicability. It also presents some interesting and difficult optimization problems. In this chapter we presented some of the optimization issues related to ad hoc networks, as well as techniques employed in their solution. This is an active area of research, and certainly will see many developments in the near future in terms of improved formulations and algorithms.

In this chapter, the time-independent Green’s functions are defined, their main properties are presented, methods for their calculation are briefly discussed, and their use in problems of physical interest is summarized.
