“…It is hard to keep a seamless experience since UE has to disconnect the previous connection and connect to the next one, the reconnection and re-authentication would bring a big interruption to user services, which may up to 1 s or even longer [23,24], and it will cause great variation to services' experience, especially for real time services.…”

Dense heterogeneous networks (HetNets) are supposed to be one of the most inevitable modalities of future radio access networks (RAN). Though the deployment of dense HetNets would allow wireless networks to achieve high data rate, it also brings severe interference, frequent handover and increasing CAPEX and OPEX, etc. Hence, the convergence of different kinds of networks is becoming more and more urgent. In this paper, a converged management architecture for HetNets (CMA) based on resource virtualization is proposed. Considering the diversity of physical resources among different networks, we virtualize the heterogeneous resources into a unified 3-D resource particle, and introduce a virtual resource layer (VRL) into CMA to govern the virtual resources. And on this basis, the architecture and key technologies of CMA are presented. Moreover, we show that CMA could whittle traditional HetNets management down to the procedure of virtual resources allocation by demonstrating some use cases. In addition, the implementation issues of CMA are analyzed.

“…More thorough security and performance analyses were presented in [23]. The protocol in [22] was used in [24] to reduce HO delays between 3GPP and WLAN. WLLR adopts slightly different messaging and key management scheme than the reauthentication protocol in [22], Our proposed protocols are designed to defend against similar types of attacks that could affect the standard protocols.…”

Abstract-Wireless technologies such as the Wireless Local Area Network (WLAN), the Worldwide Interoperability for Microwave Access (WiMAX), and the Third-Generation (3G) mobile communications system complement each other to support a variety of services suited for the home, urban, and global environments. As roaming users expect a seamless handover (HO) experience when switching from one wireless network to another, fast and secure HO operations must be supported by the networks. In this paper, we present and analyze five reauthentication protocols for HOs between WiMAX and WLANs by subscribers of networks conforming to the 3G Partnership Project (3GPP) standards. Our proposed protocols achieve outstanding performance results compared to standard protocols in terms of reauthentication signaling traffic and reauthentication delay, while fulfilling essential HO security requirements such as the provision of mutual authentication and forward and backward secrecy.

“…Some of them focused on the issue of choosing the next network based on factors like bandwidth, cost, date rate, and so forth when the device is moving out of the current network [6][7][8]. Also, several approaches were published showing how to perform a fast authentication between different access technologies when handover-took place [9][10][11]. Apart from these, a number of works have also been carried out towards addressing other handover related issues [12][13][14].…”

Seamless handover across different access technologies is very important in the future wireless networks. To optimize vertical handover in heterogeneous networks, IEEE 802.21 standard defines Media Independent Handover (MIH) services. The MIH services can be a new target to attackers, which will be the main concern for equipment vendors and service providers. In this paper, we focus specifically on security of Media Independent Information Service (MIIS) and present a new access authentication scheme with user anonymity for MIIS. The protocol can be used to establish a secure channel between the mobile node and the information server. Security and performance of the protocol are also analyzed in this paper.
