Abstract

IP mobility support is based on terminal behavior, recognizing mobility and maintaining a continuous communication session. The existing mobile IP location registration sends a message to one or more routers during a handoff within a domain by using a multicast address to process messages continuously. This implementation requires persistent message processing among all routers to determine new multicast address assignments. To solve this problem, we propose a method that enables the mobile user to obtain a QoS guarantee when the mobile device moves to an overlapping area under the mobile IP. Therefore, dynamic mobility management includes location updates under the mobile IP, and transmission of packets from the expected access points. When a handoff occurs while the mobile device is connected, the mobile host dynamically adapts to the mobility characteristics of the mobile node and transmits missed packets. In addition, by first using a location router, handoff latency reduction and packet loss requirements between domains in the overlapping mobile network environment are resolved. Second, the proposed algorithm has low-control traffic in the mobile network, allowing quick handoffs. Although instantaneous throughput is reduced during handoffs, tunneling is reduced by 10-30%, even after a handoff, by retransmitting packets missed by the mobile host, while location-registration-update times are reduced by 20-80%.

移动 IP 网络中基于 LRS 的高效动态 IP 数据传送移动性管理

IP 移动性支持以终端行为为基础，识别移动性并保持连续的通信会话。现有的移动 IP 位置注册通过使用多播地址持续处理信息，在域内切换时向一个或多个路由器发送信息。这种实现方式需要在所有路由器之间持续处理信息，以确定新的组播地址分配。为了解决这个问题，我们提出了一种方法，当移动设备移动到移动 IP 下的重叠区域时，移动用户可以获得 QoS 保证。因此，动态移动管理包括移动 IP 下的位置更新，以及从预期接入点传输数据包。当移动设备连接时发生切换，移动主机会动态适应移动节点的移动特性，并传输遗漏数据包。此外，通过首先使用定位路由器，可以解决重叠移动网络环境中域之间的切换延迟降低和数据包丢失要求。其次，建议的算法在移动网络中的控制流量较低，允许快速切换。虽然在切换期间瞬时吞吐量会减少，但通过重传移动主机错过的数据包，即使在切换后，隧道传输也会减少 10-30%，而位置注册更新时间则会减少 20-80%。
