Handoff Mobiles with Low Latency in Heterogeneous Networks for Seamless Mobility: A Survey and Future Directions
As the number of mobiles and mobile networks increases every year, the authors are facing new problems and challenges in incorporate various networks with various standards and technologies. In that the problem of handoff is a big parameter which affects the performance dramatically. Many ideas and schemes for handoff mobiles with low latency have been proposed in the past. But, because of new technologies and more number of networks increases every day, the existing ideas are no longer supported efficiently. So they need a different handoff schemes that consider the current situation. In this paper, they describe the handoff process, need for handoff, and types of handoff. Then they present a review on vertical handoff for seamless mobility.
