Packet Level Performance Analysis in Wireless User-Relaying Networks

Free registration required

Executive Summary

In this paper, the impact of user relaying on the behavior of a relay node, which acts as the source node at the same time, is analyzed in a wireless relay network at the packet level. The analysis process models the behavior of the relay node as a queuing system and represents the service for its own packet transmission as an M/G/1-type Markov chain. By considering the fact that the maximum number of packet arrivals is ordinarily limited in a practical system, the M/G/1-type Markov chain is further reformatted into a Quasi-Birth-Death (QBD) process through re-blocking so as to simplify the analysis and obtain the associated performance, such as average packet transmission delay.
