A Low Complexity Algorithm for Statistically Based Estimation of Average IP Packet Delay in Cellular Data Networks
نویسندگان
چکیده
Abstract: A new, low computation complexity technique for prediction of the average delay of IP packets, transported over cellular data networks with SR-ARQ loop, is presented in this paper. This prediction takes into account the SR-ARQ influence on the average IP packet delay, assuming that the MAC works with a static schedule policy (offering a fixed periodic access to radio resources). This assumption allows the use of this prediction as a link performance descriptor that is complementary to C/I, BER and BLER. A series of simulations and calculations have been performed to analyze the error introduced by the prediction. The results of these tests prove that the proposed method introduces a negligible prediction error, while the computation complexity is kept at a reasonable low level.
