Dynamic Rate Adaptation for Improved Throughput and Delay in Wireless Network Coded Broadcast

In this paper, the authors provide theoretical and simulation based study of the delay performance for a number of existing throughput optimal broadcast schemes and uses the results to design a new dynamic rate adaptation scheme which achieves higher transmission rates at lower packet delivery delays. Under the Bernoulli packet arrival model, the receivers' delay and throughput performance is examined. Based on their Markov states, the knowledge difference between the sender and receiver, three distinct methods for decoding are identified: zero state, leader state and coefficient-based decoding.
