Abstract

Performance of TCP can be severely degraded in Mobile IP-based wireless networks where packet losses not related to network congestion occur frequently during intersubnetwork handoffs by user mobility. To solve such a problem in the networks using Mobile IP, the packet buffering method at a base station recovers those packets dropped during handoff by forwarding the buffered packets at the old base station to the mobile users. But, when the mobile user moves to a congested base station in a new foreign subnetwork, those buffered packets forwarded by the old base station are dropped and TCP transmission performance of a mobile user degrades severely. In this paper, a PBM (Packet Buffering Marker) at a base station is proposed to prevent burst losses of out-of-profile packets during handoffs for DiffServ Assured Services. From simulation results, it is shown that PBM scheme improves TCP throughputs of an Assured Service flow during handoffs.
