Optimal Group Formation in Dense Wi-Fi Direct Networks for Content Distribution

Wi-Fi Scaling and Performance in Dense Frequency Planned Networks

The area capacity scaling of Wi-Fi has been thought to be poor due to the 802.11 MAC enforcing single transmissions in overlapped cell coverage areas. This is based on the assumption that the energy detection and virtual carrier sense MAC mechanisms at every station correctly detect ongoing transmissions and thus prevent new transmissions. However overlapped or faded packet headers can cause st...

Video distribution with edge stations and Wi-Fi delivery networks

A video distribution architecture with edge stations and WiFi delivery networks as connection to residential homes is described in this paper. An edge station is configurable and controllable by a central server. It is placed in the access point of Wi-Fi networks and has multiple usages. Due to its large storage space it can be used as a mirroring/caching proxy for continuous media. Replicating...

Band-Steering for Dual-Band Wi-Fi Access Points Optimizing Dual-Band Wi-Fi networks

Ambient Interference Effects in Wi-Fi Networks

This paper presents a measurement study of interference from six common devices that use the same 2.4 GHz ISM band as the IEEE 802.11 protocol. Using both controlled experiments and production environment measurements, we quantify the impact of these devices on the performance of 802.11 Wi-Fi networks. In our controlled experiments, we characterize the interference properties of these devices, ...

Estimation of Interference in Wi-Fi Networks

Interference is a troublesome issue that affects the throughput performance of Wi-Fi networks. Therefore it becomes crucial to estimate the interference between nodes and links of a wireless network. This approach includes passive monitoring of traffic which consists of placing multiple sniffers near network nodes to capture the wireless traffic. This traffic is analyzed to conclude about the c...
