Improving Handoff Delay In WLAN

Abstract

In this project we want to improve the process of the handoff delay in Wireless Local Area Network (WLAN) between access points (AP). where when the mobile device connected to any access point (APi) and received the power from it, and still receiving, but when the power value of these signal is decreasing or became less than the threshold power value, then these mobile device start to scan about another APj that have a power value more than the threshold power value and the signals power from the first AP (Pavi<Pth≤Pavj), then the handoff occurs. But when the power value of the signal from the old AP still good (Pavi≥ Pth>Pavj ) or (Pavi<Pth>Pavj ) then the handoff will not take place. Aim: Our project aims to solve the problem of decreasing the power value of the signal that received from any AP by laptop over long distance or any condition that make the power below the threshold value .The importance of our project take a large space specially in the hospital where there is a lot of surgery done on the network by doctor from another country where any wrong on the network cause a large danger. Not only in the hospital but in university company office…etc. V Method proposed: First, we want to study the materials that we needed in this project software and hardware and choosing a suitable network adaptor that needed later and identify it by using Mad Wifi driver and installing the Linux on the laptop to make the dealing with network adaptor more easy in addition to study the main concept on the project like WLAN scanning...etc. Materials and Equipment: We will use in this project the requirement software like Linux, MAD Wi-Fi, And requirement hardware like Access Points, mobile device, and wireless network adaptor.
