N2 - Handoff scheme provides continuous and seamless transfer when the mobile node moves around the overlay area of wireless networks. It is not practical to use the traditional Received Signal Strength Indication (RSSI) based methods to decide when to process handoff in Collaborative Virtual Environment (CVE), because the probe delay occupies most of the handoff delay time. In this paper, we propose a handoff scheme based on time interval indication (TII) in CVE over WLAN. Using the time interval between state protocol data units(PDUs) as a metric, can reduce the number of probes to decrease the probe delay in the processing of CVE. We take advantage of state forecast arithmetic to simulate object movement during processing of handoff. Numerical results demonstrate that the proposed approach reduces probe delay time in the entire operation of CVE.
