PowerNap: a power-aware distributed Wi-Fi access point scheduling algorithm

In this paper, we design a power-aware distributed access point scheduling algorithm, PowerNap, to enhance power conservation of co-existing multiple access points (APs) each having multiple clients in the same wireless vicinity. This consequently addresses low channel utilization, degraded throughput, and unfairness problems of Wi-Fi networks in an energy-efficient way. PowerNap schedules tran...

Wi Fi Protected Access-Pre-Shared Key Hybrid Algorithm

Potentially large number of cryptography solutions to attain security is widely known and recognized. Looking for a stronger scheme is the aim of most researchers to hide valuable information from each other. In this information age, many encryption algorithm exist to help keep information secure and these algorithms vary in complexity and ability to resist cracking. In this paper we present a ...

Architecting Citywide Ubiquitous Wi-Fi Access

Cities around the world are currently considering building expensive Wi-Fi infrastructure. In urban areas, resident operated Wi-Fi access points (APs) are dense enough to achieve ubiquitous Internet access, provided we can induce the hosts to provide guest Wi-Fi access. However, sharing Wi-Fi involves taking on responsibility for the guest’s actions. Our main contribution is a novel mechanism t...

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

Indoor location tracking using RSSI readings from a single Wi-Fi access point

This paper describes research towards a system for locating wireless nodes in a home environment requiring merely a single access point. The only sensor reading used for the location estimation is the received signal strength indication (RSSI) as given by an RF interface, e.g., Wi-Fi. Wireless signal strength maps for the positioning filter are obtained by a two-step parametric and measurement ...
