Several communication environments, supporting important operational scenarios such as deep space communications, Earth observation and mobile terrestrial communications, are extremely challenging for traditional TCP/IP protocols because of their intrinsic characteristic to not guarantee continuously an end-to-end path. An attractive application scenario is concerned the presence of terminals moving on a large area requiring handovers among different networks. This paper addresses mobility management through a DTN-based architecture, focusing on both routing and application level issues. In addition, a preliminary analysis of performance of a TCP-based convergence layer is carried out within satellite segment, highlighting implications on the overall architecture. Finally, TCP Noordwijk is proposed as a DTN convergence layer over satellite links and validated through NS-2 simulations.
