Towards a routing framework in ad hoc space networks

Abstract: The unique characteristics of space networks lead to different research approaches from those in terrestrial networks. In this paper, a routing framework called Space Gateway Routing (SGR) is proposed for routing through different autonomous regions (ARs) in ad hoc space networks. SGR has two integral parts: External SGR (ESGR) and Interior SGR (ISGR). ESGR addresses the delivery of different traffic types through ARs. Inside ESGR, the Location-Predicted Directional Broadcast (LPDB) is proposed for fast delivery of remote control messages and automatic data delivery. The Receiver-Initiated On-demand Routing (RIOR) is proposed for controlled data delivery, where the route discovery is initiated on-demand by the receiver, and routing tables are maintained in soft state at intermediate nodes. ISGR exchanges inter-AR routing information among border routers within an AR and schedules interAR message transmission. The Longest Queues (LQ) policy is proposed for contact allocation f...
