Impact of Message Size on the Average Delay in Narrowband Wireless Links

In this paper, the authors propose a metric of radio parameters to transmit each packet on real operational wireless networks with two fixed nodes exploring various narrowband channel spacing values. They study the impact of message size on the average delay in a wireless real-time application based on packet switching, thereafter, they show experimentally the existence of a relationship between modulation type, channel spacing, forwarding time and packet length. The practical results prove that forwarding time versus average message size offers a remarkable flexibility with efficiency in the transmission and gives a quick and easy idea of the possible time in the wireless bridge network performance.
