Model-based evaluation of location-based relaying policies in a realistic mobile indoor scenario

For WLAN systems in which relaying is used to improve throughput performance, node mobility and information collection delays can have a significant impact on the performance of a relay selection scheme. This paper analyzes this influence on the decision process using a previously developed Markov Chain model. The evaluation is done for a realistic indoor scenario that is based on ray-tracing enriched measurements from the WHERE2 project. Further, these results are compared to results obtained using an idealistic path loss model, and we show that the performance impact of node mobility and information collection delays is significantly different for the two data sets.
