Abstract :
Non-geostationary (NGEO) satellite networks can meet the requirements of next-generation Internet services with high bit rates and much lower latency than geostationary (GEO) systems. However, various characteristics of these systems dissimilar from wired and GEO systems expose some formidable challenges. Dynamic topology of the network and constraints on key system resources such as on-board CPU and memory are essential points to be considered for an efficient system design. In this paper, a novel adaptive routing mechanism in two-layered satellite network considering the network´s real time information is introduced. Adaptive routing protocol for quality of service (ARPQ) utilizes on-board processing (OBP) and avoids congestion by distributing traffic load between MEO and LEO layers. We utilize a prioritized queueing policy to satisfy QoS requirements of delay-sensitive applications while evading non real-time traffic suffer low performance level
