This work presents the performance evaluation of the cross-layer prediction framework in the context of ad hoc network mobility and multiple access interference. Node mobility influences the quality of channel prediction and, obviously, packet reception. It also leads to varying levels of interference, depending on the scenario used and the number of users received. Interference is considered from two angles: it reduces detection quality, and not all users are equally affected by glare. We begin by defining the user load. We then present simulations performed with our cross-layer conceptual framework in the various ad hoc network contexts represented by the baseline scenario, if node speed changes or if the number of supported connections increases. Numerical results are given for the entire platform in terms of reception quality and the quantities of data received thanks to variable-rate transmissions. Three speed levels and all mobility scenarios were studied. An analysis is then made to interpret the numerical results.
