An Efficient Algorithm for Fast Handoff in Wireless Mobile Networks

摘要

Mobile handoff is a relatively significant charters-tic that involves the quality of connections (QoC) between the base stations (BS) and mobile hosts (MH). Maintaining the QoC in IEEE 802.11 networks is an important challenge in wireless mobile networks, and conjointly the necessity for the different real-life wireless mobile applications. To take care of the QoC, these wireless mobile applications is responsible for fast handoffs between BS. Most of the current research is based on a neighbor graph and maintaining the neighbor table by the connected access point and calculates the scan delay. This paper has proposed a novel neighboring approach for fast handoff where scan delay has been reduced to zero by exploiting the MH neighbor table. The result shows that the proposed approach is better than state-of-the-art approaches in terms of scan delay and re-association delay.
