Research on Network Layer Host Mobility Support |
| |
| Abstract: | The development of computing techniques and communication techniques and requirements of personal communication make mobile computing and wireless networks possible and indispensable. Novel network environment offers new challenges to traditional network protocols. Especially, as middle layer protocols in the network architecture,the network layer protocols cannot support host mobility because of the hierarchical addressing and routing mechanisms and static name and address binding.New functions and protocols must be added in order to support host mobility in the network layer. In this paper we summarize the impact of host mobility on network protocols ,the problems of traditional protocols to support host mobility ,the architecture and practical schemes to support host mobility in the network layer ,and the emphases ,current status and direction of network layer host mobility support. |
