Authors: G.Kousalya and P.Narayanasamy and T.G.Srinivasalu
Abstract: Paper designed to minimize the handoff latency in IEEE 802.11 wireless local area networks. Mobility management in wireless/mobile network is another major issue. The algorithms for low latency handoff with reduced data loss and signaling overhead needs to be developed. We have proposed a novel pre-handoff initiation algorithm along with threshold points to reduce the handoff latency during inter and intra subnet handoff. In our approach we proposed to divide the base station (BS) range into two zones namely Z1- Good, Z2 -Average zone based on the signal strength as well as current location. Our pre handoff initiation algorithm is triggered when the mobile unit (MU) enters the threshold minimum (Thmin) point; it receives the information about the candidate BS with QoS parameters. This reduces the layer 2 ( L2 ) latency and improves the performance of handoff process compared to the conventional blind handoff process
