Joint Optimization of Throughput and Packet Drop Rate for Delay Sensitive Applications in TDD Satellite Network Coded Systems
In this paper, the authors consider the issue of throughput and Packet Drop Rate (PDR) optimization as two performance metrics for delay sensitive applications in network coded Time Division Duplex (TDD) satellite systems with large Round Trip Times (RTT). They adopt Random Linear Network Coding (RLNC) under two different scenarios, feedback-less and with feedback, and their goal is to jointly optimize the mean throughputs and PDRs of users in the system. For this purpose, they propose a systematic framework and start with formulating and optimizing these performance metrics for the single-user case. This framework enables one to analytically compare the performance metrics under different system parameters and settings.
