TL;DR: The Fast Scan scheme is proposed which reduces the scanning delay by using a client-based database and the net handoff delay is reduced for IEEE 802.11b networks.
Abstract: IEEE 802.11 Wireless LANs are increasingly being used in real environments for broad-band access. Such large scale IEEE 802.11 WLAN implies the need for client station support from one Access Point to another. The client stations (STA) can move freely, but because of the short range of their Access Points (APs), they usually need to reassociate with different APs and communicate through them. When changing APs, a client station starts a process known as a handoff that can take up to few seconds, which is too long for real-time applications such as Voice over IP (VoIP).Various solutions have been proposed to change or improve the client behavior when doing a handoff. The delay incurred in scanning for APs across channels contributes to 90% of the total handoff delay. In this paper, the Fast Scan scheme is proposed which reduces the scanning delay by using a client-based database. The net handoff delay is reduced for IEEE 802.11b networks. The proposed schemes do not need any changes in the infrastructure (access points) and require only a single radio and a small cache memory at the client side.

TL;DR: In this article, a dual network access point capable of establishing a home wireless network and a further secondary wireless network for a number of wireless devices is proposed, where the access point monitors the devices connected to the first network and adjusts the advertised minimum supportable rate on the second network.
Abstract: A dual network access point capable of establishing a home wireless network and a further secondary wireless network for a number of wireless devices. The first wireless network is a private home WLAN while the second wireless network is a guest network or a hotspot network. To prevent secondary network users impacting the performance of the first network, the access point monitors the devices connected to the first network and adjusts the advertised minimum supportable rate on the second network.
