Transactional model of a company based on the Hub-Spoke and LDPC/MIMO models

This paper offers a description of a new transactional model designed for a m-commerce 4G architecture, and the economic benefit that it can bring to an organization. For the design, it has been used a Hub and Spoke transport model for the material flow, a Queuing model for the bank company transactions flow, and a LDPC/MIMO channel for the transmission environment. With the new system, the SNR can be reduced approximately in 8 dB, which makes possible a greater rapidity in the transactions. The global results show an economic gain of at least a 20.12%, because of the redesign of the conversations, the optimization of the Transport Problem using the Hub and Spoke Model and the reduction in the errors of the sent data.
