Bounded Fano Decoders over Intermediate Hops Excluding Packet Retransmission

Fano decoding algorithms are packet error detection and correction mechanisms that are mainly used to ensure a reliable end-to-end delivery over noisy channels. The popularity of using Fano decoding gets high in many network environments because of its lower storage requirements and having a decoding complexity that is a channel dependent. In this paper, we propose a new queuing study over the systems of intermediate hops that implement Fano decoders that are bounded by upper and lower threshold decoding limits. These threshold limits make our study to be general so that it can be adapted in any network environment especially the networks that are affected much in noise. There is no packet retransmission included in our queuing study for those packets that needs time above upper threshold limit. They are considered to be lost. We aim in this queuing study to have an expression about the average number of packets in the decoder´s buffer that are waiting to get service.
