“…The signaling cost can be defined as the total authentication signaling message traffic during a communication session [25]. Since the BS scanning messages and the UE registration are the same for all handovers protocols, our study is focused only on the handover control messages.…”

The Initial Network Entry Authentication (INEA) process is the first security entry between client and WiMAX network. WiMAX architecture provides a significant flexibility to respect wireless security requirements. The INEA framework is based on the Extensible Authentication Protocol (EAP) for user authentication and key management. However, EAP authentication method introduces high authentication delay and signaling cost when the user moves between stations. These impact negatively the handover process and decrease the Quality of Service of WiMAX networks. In this paper, we analyze the existing INEA authentication process and we propose a new authentication method and key agreement for handovers process. To prove the new method validity, the verification is performed by using the formal security analyzer Automated Validation of Internet Security Protocols and Applications which is a performed tool to find automatically potential attacks in security protocols. Furthermore, the proposed protocol is compared with other handover protocols. The comparison shows that proposed protocol outperforms the other protocols.

Interworking UMTS and WiMAX networks offers global roaming and cost effective broadband wireless Internet access. Designing efficient Intra and Inter WiMAX handovers in the interworking architecture is a challenging problem. Handovers must be instantaneous and secure at the same time. We attempt to solve this problem by designing Intra and Inter WiMAX handover protocols which are capable of operating in the UMTS-WiMAX interworking architecture and perform mutual pre-authentication between the mobile station and the target network prior to handover. Due to the pre-authentication procedure, our proposed handover protocols outperform standard handover protocols by dispatching fewer handover signaling messages, experiencing less handover delay and preserving computation resources of critical nodes in the interworking architecture. Furthermore, our proposed handover protocols meet essential security requirements and defend against common attacks affecting handover protocols.

“…Indeed, recent wireless networks have various characteristics in terms of latency, bandwidth, frequency and coverage. For example, third generation (3G) cellular networks, such as the Universal Mobile Telecommunication System (UMTS) provide low bandwidth and wide coverage [1]. In contrast, wireless local area networks (WLANs) such as IEEE 802.11 and the European high performance radio LAN (HiperLAN) provide high bandwidth and small coverage [2].…”

Vertical handoff is one of the most important issues for the next generation heterogeneous wireless networks. However, in many situations, unbeneficial vertical handoffs occur across intersystem heterogeneous networks cause network performance degradation. Therefore, we propose a novel configuration architecture that can be deployed in the next generation of wireless networks. Second, we propose a predictive and adaptive Vertical Handoff Decision Scheme that optimizes the handoff initiation time as well as selection of the most optimal network. The proposed vertical handoff decision algorithm considers the technology type as well as the Signal to Interference Ratio (SIR), the Mobile Station (MS) velocity, the user preferences, the applications requirements and the terminal capabilities as the most important factors to make vertical handoff decision. In order to minimize handoff costs, the proposed decision algorithm uses the dwell timer concept. The handoff costs are analyzed in terms of unnecessary and unbeneficial handoffs rate.The simulation results show that the reduction of unnecessary handoffs proposed in our vertical handoff decision scheme reduces the handoff blocking probability, the packets loss rate and the handoff overhead
