    The paper presents an analytical model for the prediction of multipath fading signal of land mobile satellite (LMS) channels, when non-GEO satellites are used. These satellites introduce a Doppler shift to the received mobile antenna signal, due to the movement with respect to the scatterers and the mobile receiver. The effects of this movement are investigated with reference to the received elect... View full abstract»

    An analytic model is presented for a partially reliable transport protocol based on retransmissions. The model illustrates tradeoffs between two QoS parameters (delay and throughput), and various levels of reliability. The model predicts that the use of a reliable transport service when an application only needs a partially reliable one causes considerable throughput decreases and delay increases ...
