With the Canetti-Krawczyk (CK) model, we analyze the authentication module WAIs in the Chinese WLAN national security standard WAPI and its implementation plan respectively. The security weaknesses of WAI in the original WAPI are presented; then WAI in the implementation plan is proved secure in the CK model; at last we point out how the implementation plan overcomes the security weaknesses in ...

Design interest for an efficient call admission control (CAC) scheme for a mixed cell (i.e., a 3G cell with embedded WLAN hotspots) is proliferating for the traffic load sharing between 3G and WLAN to improve system capacity and performance as well. Some article proposes CAC schemes to increase 3G system capacity and to reduce dropping probabilities of handoff calls by using WLAN hotspots. Most...

Over the past few years, Wireless Local Area Networks (WLANs) have been extensively deployed and have significantly evolved. However, the deployment of large-scale WLAN still presents management issues. Moreover, while newer WLAN technologies and services have been emerging at a prolific rate, the architecture of WLAN networks has been quite static and has seen difficulties to evolve. In this p...

This paper proposes a novel load balancing scheme, for an operator-deployed cellular-WLAN heterogeneous network (HetNet), where the user association is controlled by employing cell breathing technique for the WLAN network. This scheme, eliminates the complex coordination and additional signalling overheads between the users and the network, by allowing the users to simply associate with the ava...

Wireless local area network (WLAN) has been widely used in many sectors. The popularity gained is due to many reasons, such as ease of installation, installation flexibility, mobility, reduced cost-of-ownership, and scalability. However, regardless of the benefits, WLAN have some security threats. This paper begins by introducing the concept of WLAN. The introductory section gives brief informa...

© 2013 ETRI Journal, Volume 35, Number 6, December 2013 http://dx.doi.org/10.4218/etrij.13.0213.0404 Dual-mode terminals (DMTs) equipped with cellular and WLAN interfaces have become popular in recent years. Users of DMTs can enjoy high-speed WLAN Internet access and wide area Internet access to cellular networks. However, a DMT may consume power inefficiently when discovering a WLAN with inher...

The WLAN are coming more and more significant factor in telecommunications business. The success of WLAN hotspot networks is increasing and the new GAN/UMA solution is being launched. It is very crucial time in WLAN business and especially for mobile operators. The question is, how they are going to gain from WLAN in most competent way. In this paper is first analyzed some WLAN solutions in the...
