> 中文摘要: 提出一种预查询移动支持方案(mobile Internet protocol_based on location pre-query,简称MIP_Q),以解决家乡网络的流量瓶颈和单点故障问题,从而提高移动通信的效率和可靠性.MIP_Q通过扩展域名服务系统管理和跟踪移动节点的当前位置信息,省去了家乡代理;采用并行切换控制方式,同时避免了MIP(mobile Internet protocol,简称MIP)中的三角路由和隧道路由问题;借助有效的计算方法,分析和比较了MIP_Q与MIP,MIP_LR的平均移动通信成本和切换时延;在实现方面与广泛应用的广域蜂窝移动网络进行了类比.结果表明:MIP_Q在切换效率和新增实体数等方面优于同类方案;MIP_Q可以极大地降低节点的移动通信成本,减小切换时延;MIP_Q具有良好的可行性.最后提出MIP_Q的仿真和实现方案.
Abstract: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.
