Recently, the High Efficiency WLAN or simply HEW study group was created within IEEE 802.11 working group. This study group considers the improvement of spectrum efficiency to enhance the system's area throughput in high density scenarios. Subsequently, this led to the creation of a new task group called 802.11ax, which is expected to deliver the next Wi-Fi(More)
The rate control mechanism is an effective way to improve the overall system performance in IEEE 802.11 multi-rate networks. However, in dense environments, due to the large number of contending nodes, the packet collisions trigger unfairly the rate control mechanism to decrease the transmission data rate. In this work, we address the performance(More)
In an IEEE 802.15.3 Wireless Personal Area Network (WPAN), an extension of the communication area by the formation of a multi-piconet is one of the most challenging issues. The standard defines a Parent/Child architecture with a centralized decision making. The parent PicoNet Coordinator (PNC) takes exclusively the decision of accepting a child piconet(More)
