The proposed research project addresses adaptive routing in packet-oriented non-geostationary satellite networks with intersatellite links (ISL). The emphasis of the study is on the design of efficient per-hop routing algorithms for connectionless networks, which are taking into account combined metrics with quality of service parameters and are trying to provide uniform traffic load distribution among ISLs. The study will first identify criteria for the selection of the most suitable routing algorithm and parameters for adaptation, which will be followed by the analysis of existing routing algorithms in non-geostationary satellite networks. The design of adaptive routing algorithms will start with the definition of suitable link-cost metrics for adaptive routing and the selection of link cost function. Furthermore, the study will propose forwarding policies for alternate link routing, suitable for optimisation of network performance and improvement of resources utilisation. The proposed routing algorithms will be adapted so as to support path selection according to diverse traffic characteristics leading to type of service routing. Finally, the most suitable mechanisms to introduce certain degree of QoS guarantees in the proposed routing algorithms will be identified and their complexity assessed. A suitable ISL routing model will be developed as a part of the proposed research project. Built on a packet level and using modular approach this model will allow performance comparison of different routing algorithms considering different traffic flow models. Thus, the existing models for traffic generation in a simulation model of non-geostationary satellite network will also be analysed and the most suitable approach will be taken to develop traffic flow models with different concentration of sources and flows.
