In recent years, wireless local area networks have been developed and deployed in many wireless applications. When the Mobile Node (MN) accesses different access points (APs), handoff latency may cause packet loss and result in serious problems in real-time applications. Also, although, the mobility between access points was initially not a major concern, the inter-AP mobility becomes an essential issue in WLAN towards the paradigm of ubiquitous computing. This project proposes an efficient soft handoff scheme realized by dual handoff. The mobile node maintains two active links to forward and backward access points respectively and the handoffs are never simultaneous to ensure one data link or thoroughfare always exists.
