On the Delay and Energy Performance in Coded Two-Hop Line Networks with Bursty Erasures
The authors consider two-hop line networks where the communication links are bursty packet erasure channels modeled as a simple two-state Gilbert-Elliott channel. The first and second node in the line has local information with Poisson-distributed arrivals available and intends to communicate this information to the receiving node in the line. They consider an online approach and random linear network coding for erasure correction. They provide a queueing-theoretic analysis of two different models, a genie aided full duplex model and a partially genie aided half-duplex model, where the genie only provides the channel state information.
