Transport layer mobility protocols: Issues, challenges and a comparative study

Mobility of Internet hosts allows computing nodes to move between subnets while being connected to the remote nodes. To provide seamless connectivity to the roaming users, several mobility protocols have been developed at different layers. Some schemes have been proposed in the transport layer. However, no research has been performed to analyze different transport layer mobility schemes. In this paper, we have discussed a number of transport layer mobility protocols. We have identified different mobility related issues and have chosen a number of evaluation criteria to critically analyze existing transport layer mobility schemes. Our critical analysis can help reader understand the strengths and weaknesses of these mobility schemes.
