Buffering study over intermediate hops including packet retransmission

Abstract

Sequential decoding is one of the most important convolutional code's algorithms that can work in intermediate hops efficiently. It is of interest since its error detection and correction techniques are considered to be variable and dependent to channel state. In this paper, we conduct a new buffering study over intermediate hops' systems that employ sequential decoding algorithms. As a result of that, we find a closed form expression for the expected buffer occupancy under different assumptions. Our study can be applicable to any network environments that are affected by noise which consequently leads to high packet error rate. The results are presented and explained when considering different system's parameters.
