Optimal Frame Payload Size for Mobile Communications over Wireless Links of Cellular Networks

Internet accesses from mobile phones over cellular networks suffer from severe bandwidth limitations and high bit error rates in the wireless access links. Tailoring wireless link connections to best fit the characteristics of the link is thus very important. In this work, we propose a simple algorithm to find the optimal frame payload size in order to maximize the effective utilization of the wireless link. With some numerical examples, it is shown that the optimal frame payload size becomes a constant value when the window size of the wireless link exceeds a threshold. One can set the frame payload size of the wireless link to this optimal frame payload size for maximum efficiency on the expensive wireless link.
