Achieving IP handoff with a short latency and minimal packet loss is essential for mobile devices that roam across IP subnets. Many existing solutions require changes to be made to the network or transport layer, and they tend to suffer from long handoff latency in either soft or hard hand-off scenario, or both; and some are difficult to deploy in practice.(More)
We compare the performance of three handoff protocols , namely Mobile IP, Fast Handoff and mSCTP. Among the three schemes, Mobile IP suffers from the lowest data throughput and longest handoff latency. Fast Handoff can perform better, provided that the mobile node can handoff to the new base station at an appropriate time instant when data forwarding(More)
