Power and throughput optimization in Ad-hoc cooperative MIMO systems

The large number of network nodes and the energy constraints make the field of wireless networks, especially Ad-hoc network one of the most important application fields for Cooperative Diversity. In this paper we presents a new architecture based on the principle of cooperation between the terminals, in which MIMO technology is virtually introduced to transmit information, taking benefit from the existing of different nodes and making use of diversity in an Ad hoc network to improve the QoS. The objective is to build new steps to be followed to apply our ‘MIMO Cooperative’ model to an architecture network which already exists within a medium of ad hoc mode, by taking into account the interaction between the various layers and the analysis of the performances. Then, we will be choosing the suitable parameters in order to maximize the Throughput and we will add a function which helps calculate the optimum capacity while keeping a higher flow which is our interest within the framework of this work.
