dc.description.abstract Unidirectional satellite communications becomes much popular because of wide geographic coverage, multicasting features. These features support several one-to-many applications where asymmetric connection is sufficient. At the same time, satellite communications have some disadvantages like inherent noise in the channel or high loss rate because of some weather condition like rain, fog etc. Several multicast transport protocols have been proposed to these applications for UDL where reliability is maintained by a narrow backchannel. Much less works have been devoted to maintain reliability in UDL without backchannel where many receivers are concerned. In this situation, it becomes very much necessary to study about the packet loss patterns in different satellite receivers and how efficiently the packets can be recovered among recipients without contacting to the sender. In this study, a detailed analysis of multicast packet loss patterns is shown with experiments in a real satellite network test bed. An analysis for average number of packet loss by many receivers is also shown those can be recovered by the receivers communicating among themselves without requesting for the lost packets back to the sender. A simple bitmap data structure (fingerprint) named Mixed-PEDbit is designed for the receivers as if they can exchange the packet information (received or lost) with other receivers (peers) with reduced communication. Additionally, a recovery framework is recommended to apply these bitmap data structures.
