Abstract


In order to meet the demand for wireless communication users , improve service quality, many domestic and foreign researchers are working on how to reduce the switching delay to ensure the quality of communication. This paper reviews a number of domestic and international aspects of the handover latency on references, describes several typical fast handover method to analyze these methods switching delay processing their disadvantages and advantages . On the basis of the existing programs , this paper presents two rapid switching method . One is based on hierarchical mobile IPv6 flow under the fast switching method, it will stream-based hierarchical structure of thought and ideas effectively combine . In this method, flow state information to determine the binding update message whether the node after the cross routers, if so, then the crossover router between the new location of the mobile node to establish a temporary tunnel to the mobile node from the communication node data flow will is redirected to the new location of the mobile node , without the need to wait for completion of the registration process , thus reducing the switching delay of the downlink data stream . At the same time , it uses the mobile anchor point of the mobile node's movement is divided into macro- and micro- moving mobile , since the mobile processes are usually carried out in a domain , only a registration to the mobile anchor point , thus greatly reducing the registration overhead and reduces the upstream switching delays. Another is to support route optimization in mobile IPv6 network stream-based fast switching method, which determines the use of flow information has reached a cross router , if so, then sent to the home agent blocking the binding update message and modify its binding cache , and a binding approval message is sent back to the mobile node so that the mobile node and the correspondent node data packets to the mobile node through a cross between the router and the optimal route directly to each other, thereby reducing both the downstream and upstream data flow switching time data stream . Then use NS2 simulator , networking topology, these two scenarios simulation. The experimental results show that both the new stream-based approach than the standard switching, hierarchical switching with less switching delay time.
