“…In the loose coupling approach, the WLAN gateway does not have any direct connection to UMTS network elements. WLAN traffic would not go through the UMTS core network [10]. In this approach, UMTS and WLAN can use different mechanisms and protocols to handle authentication, mobility, and billing.…”

Wireless local area networks (WLANs) are providing the most economical means of internet access. However, their access is very much limited. They can be deployed in a large scale by integrating them with cellular networks such as universal mobile telecommunication system (UMTS), general packet radio services (GPRS) etc. A seamless roaming between these two hetero networks can be ensured through mobile IP. But the two networks don't have support towards mobile IP which requires the deployment of home agents and a protocol between the mobile nodes, home agents and foreign agents. Hence seamless roaming can be provided by incorporating Mobile IP support in 802.11 (WLAN) networks. The cellular networks require the home agent placement to be placed and the appropriate home agents to be assigned. The home agent placement and home address assignment are the issues for supporting Mobile IP for heterogeneous roaming. If the mobiles use a home agent (HA) that is deployed in a UMTS network when roaming in a WLAN network, the UMTS network may get overloaded with WLAN traffic. The solution to this problem is to dynamically assign an HA in the WLAN domain. Different architectures can be obtained by placing HA at different positions each having its own shortcomings, in which HA is placed between border router and GGSN that requires HA performing very high speed routing as fast as GPRS gateway signaling node (GGSN) which is practically not possible occurring in the existing architecture. To overcome these difficulties different architectures are proposed in this paper. In the first architecture the HA and GGSN is connected to the border router instead of tightly coupling the HA to the GGSN, and the second architecture is HA can be collocated with one of the GGSN in UMTS network and in the third architecture, GGSN is the default router of the mobile nodes (MN) under its coverage area, the foreign agent (FA) is best collocated with the GGSN. Based on the observation of proposed architectures through performance metrics on packet overhead an attempt towards dynamic home agent assignment has been proposed.

“…The objective penetration level between the 3G networks and WLANs and the provisioned services lead to different requirements for the interworking mechanisms. The services supported in future integrated 3G/WLAN networks are envisioned in Axiotis et al (2004). However, the integration of the two technologies will be a gradual development process.…”

“…It is expected that in a 3G/WLAN integrated network the wireless terminal will be dual-mode, which means that the terminal will be equipped with network interfaces to both 3G networks and WLANs (Axiotis et al, 2004). However, only one subscription is needed with a 3G operator or a WLAN service provider, who has roaming agreements to support the interworking (Buddhikot et al, 2003a).…”

Abstract:The Third Generation (3G) cellular networks provide ubiquitous connectivity but low data rates, whereas Wireless Local Area Networks (WLANs) can offer much higher data rates but only cover smaller geographic areas. Their complementary characteristics make the integration of the two networks a promising trend for next-generation wireless networks. With combined strengths, the integrated networks will provide both wide-area coverage and high-rate data services in hotspots. There are many aspects involved in their interworking, such as mobility, security and Quality of Service (QoS) provisioning. In this paper, we present a survey of most recent interworking mechanisms proposed in the literature, and outline some important open issues to achieve seamless integration.Keywords: 3G/WLAN interworking; tight/loose coupling; mobility management; quality of services; QoS provisioning.

Fourth-generation wireless networks may require an integration of mobile ad hoc networks (MANET) into external network to enhance the flexibility of the communication and roaming. This phenomenon is well-suited for commercial and military applications which yield additional benefit of roaming. However, integration of MANET with external network poses a serious security challenge for communication because of open and distributed nature of the ad hoc network. In this paper, a secure privacy preserving architecture has been proposed to provide privacy and security for data communication in wireless mobile ad hoc networks. This architecture includes the concept of observer obscurity to provide privacy and security for the genuine nodes and to exclude misbehaving nodes in the network. The proposed architecture is designed based on the k-times anonymous authentication and onion routing -a cryptography concept which supports for anonymous communication. The simulation results prove the necessity and effectiveness of the proposed architecture in achieving such privacy and security in the integrated environment.
