Networks based on HAPs will have both access and transport interfaces. In this paper we deal with the design of an optical transport network (OTN) for HAP based networks, namely with the dimensioning, analysing and evaluating the performance of such a network. A simulation tool that implements several routing and wavelength assignment algorithms for wavelength-routed networks was built. Simulations showed that a good routing algorithm combined with a simple wavelength assignment policy can significantly reduce the blocking. For large networks, such as the 35 node European network, double (multi) hop routing is necessary in order to fully interconnect the nodes of the network.
