Recently, the issue of unnecessary handoff in WLAN networks has been the subject of recent research efforts. WLANs are designed to provide high-speed connectivity in a limited area, similar to their wired counterparts. The IEEE 802.11 Standard has become widely adopted for wireless LANs. The handoff algorithm allows mobile nodes to switch between access points (APs) as they move between areas serviced by different APs. However, determining when to initiate a handoff poses challenges, particularly concerning unnecessary handoffs. Many researchers have investigated this issue and have proposed mechanisms to address it. Thus, this study focuses on reviewing the related works about handoff and discusses the challenges and recent advances.
