Abstract
We have considered fast handoff algorithms to support seamless streaming in wireless LANs. It is impossible to provide seamless streaming service while moving within wireless LANs, In this paper, we proposed a new handoff algorithm where the critical value for handoff can be adjusted according to peripheral wireless circumstances. This algorithm can prevent an unnecessary scanning job and save handoff delay time through the active scanning procedure to the specific channel groups. Also, we evaluated the handoff performance of our proposed algorithm, and compared it with the performance of the existing wireless LAN. We can see that the performance with our proposal is better than that of the general wireless LAN.
