Freeze Dead Line Algorithm for Vertical Handoff in Heterogeneous Wireless Networks

Abstract

In this paper, we propose an algorithm to solve handover problems in heterogeneous wireless networks. Many previous studies concentrated on the lower level layer to solve handover problems. In this paper, we concentrate on high level handover problems such as network and transport layers. We solve handover problems of the transport layer in a heterogeneous wireless networks and propose a Freeze DeadLine (FDL) algorithm for better performance. The proposed method is analyzed from a theoretical perspective and is verified using the Network Simulator– 2.
