Abstract
Performance of TCP can be severely degraded in WLP-based Mobile IP networks due to packet loss. It is not related to network congestion that occurs frequently during inter-subnetwork handover of user. To solve this problem, packet buffering method recovers packets dropped during handover by forwarding packets buffered at old BS to mobile nodes. But if a mobile node moves to a congested BS of a new foreign subnetwork, buffered packets will be dropped. And TCP transmission performance of the mobile node degrades severely. In this paper, we propose a buffer management with considering handover to provide a new disposal standard for handover packets. Simulation results show that the proposed buffer management provides a link utilization improvement in congested wireless links.
