One of the main issues in the fourth generation (4G) wireless networks is the vertical handoff decision. The handoff is the mechanism used in order to let a mobile node (MN) switches from a network to another without remarkable service disconnection. Thus, the delay consumed to choose the suitable network to which the MN may connect is a major issue, which may impact the offered quality of service (QoS). In this paper we will present a Secured Vertical Handoff Decision (Sec-DVHD) scheme using the PKI algorithm, which is an extension of our proposed scheme, the distributed vertical handoff decision (DVHD). The simulation shows a good performance of the Sec-DVHD in term of handoff blocking rate and throughput.
