%X In this paper, an approach for IP mobility support with Location Pre-Query (MIP_Q) is put forward for solving the traffic bottleneck and single point error at home network, and also for improving the efficiency and reliability of communication. MIP_Q eliminates the agent of HA (home Agent) by extending the functions of DNS (domain name system) to manage and track the location database of mobile nodes. MIP_Q uses parallel handoff procedures and avoids the triangle routing and tunneling. The cost and handoff delay of MIP_Q by an effective algorithm with MIP and MIP_LR are analyzed and compared. The realization of MIP_Q is also discussed by referring to the widely used wide area cellular mobile networks. The analysis results show that MIP_Q precedes MIP and MIP_Q on handoff efficiency and the number of additional entities. MIP_Q can greatly reduce the mean cost of mobile communication and lead to a reasonable handoff delay. MIP_Q also has feasibility on implementation. Finally, the MIP_Qs simulation and implementation schemes are given out.
