Satellite communications networks are characterized by high bandwidth and ease of mobility with minimum coverage cost. However, when certain network topologies (i.e., Geo-synchronous Orbit [GEO] satellites with fixed terminals, GEO with mobile terminals, and Low Earth Orbit satellites) are of concern, high computational complexity issues arise. Because of network topology characteristics, so many of the network formations that give optimal performance are required to find scalable and stable solutions subject to large sizes and mobility of the networks. Primary interests of this research opportunity are in integrated systematic approaches and guidelines for overlay protocols that interface with either the transport layer or lower layers. Specifically, distributed network topology formations with polynomial complexity are desired to automatically endow nodes in the network some autonomy to decide whether to make links with neighbor nodes or not, while considering the cost required for link formation. In addition, with respect to the bottleneck issue incurred by the multi-source multicast flows, network coding is being considered as a promising technique that is capable of enhancing efficient resource usage and improving robustness and throughput.
