PS-Net : Personalized Secure Wi-Fi Networks

Designing High Performance Enterprise Wi-Fi Networks

Use of mobile computing devices such as laptops, PDAs, and Wi-Fi enabled phones is increasing in the workplace. As the usage of corporate 802.11 wireless networks (WLANs) grows, network performance is becoming a significant concern. We have built DenseAP, a novel system for improving the performance of enterprise WLANs using a dense deployment of access points (APs). In sharp contrast with wire...

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, ...

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

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...

Eliminating Communication Redundancy in Wi-Fi Networks

Studies have shown the presence of considerable amounts of redundancy in Internet traffic content. Recent works are exploring possibilities for exploiting network traffic redundancy, but these works invariably focus on fixed wireline networks. Unlike wireline networks, wireless and mobile environments exhibit unique challenges and opportunities in the context of redundancy elimination. In this ...
