QMIP: Query-based Mobile IP for performance enhancement

Mobile IP (MIP) suffers from the so-called triangular routing problem. Moreover, MIP Home Agent (HA) tends to undergo server data traffic load, since it should deliver all the data packets toward mobile nodes. This Paper proposes a simple extension of MIP, called Query-based MIP (QMIP), in which the binding query to HA will be used to get the care-of address of a mobile node and to deliver the subsequent data packets over the optimized data path. The proposed QMIP scheme can be applied to MIPv4 and Proxy MIPv6 as well. By analysis, we show that the QMIP can reduce the overall transmission delays of data packets to mobile nodes, compared to the MIP.
