说明：  本文正是在研究WIMAX/802.16e协议和FMIPv6协议的基础之 上，提出了基于FMIPv6的WIMAX网络快速切换机制，该方案采用跨 层切换的思想，MAC层联合网络层同时进行切换，在链路尚未断开 之前即完成新转交地址(NCOA)获取等功能，从而加快了切换进程， 减小了切换时延和切换时的丢包率。在提出本切换机制的基础上，本 文在NSZ仿真平台上对所提出的切换方案做了系统性的性能仿真，通 过仿真结果验证了方案的可行性和优越性。 ( In this paper, IEEE802.16e standard is described at first. Then an introduction for the basic knowledge and research in MIPv6 and FMIPv6 protocol is given. A fast handover scheme of WiMAX network which based on FMIPv6 protocol is suggested, which implements the fast handover at IP layer associating with MAC layer at the same time. scheme minimizes handover latency by predicting and preparing This the impending handover in advance. Finally, simulation are carried out to evaluate the performance of this fast handover scheme. The result of the simulation shows that the fast handover scheme has good performance. )

For a given source vertex (node) in the graph, the algorithm finds the path with lowest cost (i.e. the shortest path) between that vertex and every other vertex. It can also be used for finding costs of shortest paths from a single vertex to a single destination vertex by stopping the algorithm once the shortest path to the destination vertex has been determined. For example, if the vertices of the graph represent cities and edge path costs represent driving distances between pairs of cities connected by a direct road, Dijkstra s algorithm can be used to find the shortest route between one city and all other cities. As a result, the shortest path first is widely used in network routing protocols, most notably IS-IS and OSPF (Open Shortest Path First).
