A Fast Handoff Mechanism for Bluetooth Network Access Points

The handoff for Bluetooth network access points is a critical issue before Bluetooth technology is applied widely The special characteristics of Bluetooth technology present great challenges in studying and implementing fast handoff of access points Presented in this paper is an innovative backward soft handoff mechanism controlled by access point to realize fast handover The access point supervises the link between itself and the mobile point in real time and calculates the value to determine handover according to the distance and the link quality While the value is more than one threshold, the access point searches in advance for the optimal candidate from its neighborhood While the value continues to surmount another threshold, the mobile point is switched to a new access point Deducing from the simulations of the virtual handoff scenarios, it validates that the scheme finishes the handoff procedure in a very short time
