Center node: "reliability bounds for delay constrained multi hop networks"
  Abstract: We consider a linear multi-hop network composed of multi-state discrete-time memoryless channels over each hop, with orthogonal time-sharing across hops under a half-duplex relaying protocol. We analyze the probability of error and associated reliability function \cite{Gallager68} over the multi-hop network; with emphasis on random coding and sphere packing bounds, under the assumption of point-to-point coding over each hop. In particular, we define the system reliability function for the multi-hop network and derive lower and upper bounds on this function to specify the reliability-optimal operating conditions of the network under an end-to-end constraint on the total number of channel uses. Moreover, we apply the reliability analysis to bound the expected end-to-end latency of multi-hop communication under the support of an automatic repeat request (ARQ) protocol. Considering an additive white Gaussian noise (AWGN) channel model over each hop, we evaluate and compare these bounds to draw insights on the role of multi-hopping toward enhancing the end-to-end rate-reliability-delay tradeoff.
