Towards a Collision-Free WLAN: Dynamic Parameter Adjustment in CSMA/E2CA
Carrier sense multiple access with enhanced collision avoidance (CSMA/ECA) is a distributed MAC protocol that allows collisionfree access to the medium in WLANs. The only difference between CSMA/ECA and the well-known CSMA/CA is that the former uses a deterministic backoff after successful transmissions. Collision-free operation is reached after a transient state during which some collisions ma...
متن کاملCollision-free Operation in High Density WLAN Deployments
WiFi’s popularity has led to crowded scenarios composed of many Access Points (AP) and clients, often operating on overlapping channels, producing interference that gravely degrades performance. This misallocation of resources is often the result of multiple WLANs ownership, that is, networks are frequently setup automatically without considering neighbouring APs. In this work we overview the e...
متن کاملTowards a Dynamic Adjustment of the Language Weight
Most speech recognition systems use a language weight to reduce the mismatch between the language model and the acoustic models. Usually a constant value of the language weight is chosen for the whole test set. In this paper, we evaluate the possibility to adapt the language weight dynamically to the state of the dialogue or to the current utterance. Our experiments show, that the gain in perfo...
متن کاملDeclutter and Resample: Towards Parameter Free Denoising
In many data analysis applications the following scenario is commonplace: we are given a point set that is supposed to sample a hidden ground truth K in a metric space, but it got corrupted with noise so that some of the data points lie far away from K creating outliers also termed as ambient noise. One of the main goals of denoising algorithms is to eliminate such noise so that the curated dat...
متن کاملPlayer Modeling Using HOSVD towards Dynamic Difficulty Adjustment in Videogames
In this work, we propose and evaluate a Higher Order Singular Value Decomposition (HOSVD) of a tensor as a means to classify player behavior and adjust game difficulty dynamically. Applying this method to player data collected during a plethora of game sessions resulted in a reduction of the dimensionality of the classification problem and a robust classification of player behavior. Simultaneou...
