MIMO systems take advantage of multiple antennas at the transmitters and receivers, as well as multipath propagation, to provide more reliable, higher capacity wireless links. As a result, these links can support a set of much higher data rates than single-input single-output (SISO) links. However, it is not always optimal for a node to transmit at its largest supported rate. Depending on various factors, it may be more efficient for a node to transmit at one of its lower transmission rates. One metric that can be used to determine the optimal transmission rate for a packet over a MIMO link is goodput. In this thesis, we derive a model for a MIMO link between two wireless nodes. This model includes a method for simulating successful packet transmission based on the distribution of the link’s capacity. In addition, the model uses the goodput metric to select the optimal transmission rate for a packet from a MIMO link’s set of achievable rates. Through the use of MATLAB and modifications to the Network Simulator (NS-2), our MIMO link model is incorporated into NS-2 and simulations are executed for experimental data.","abstract_html":"Over the years, multiple-input multiple-output (MIMO) technology has become more prevalent in modern wireless communication systems.
