“…In Diab et al (2007) a generic mathematical model is proposed for performance analysis of mobility management protocols but the focus of this model is also Mobile IP and it does not discuss the end-toend solutions. Murthy and Phiri (2005) have discussed handover latency in WLAN/GPRS inter-working system and identified the parameters that affect the handover latency. A survey of mobility management protocols has been carried out in Shah and Yousaf (2008) and Al-Surmi et al (2012).…”

“…The increasing popularity of Wireless Local Area Network (WLAN) enabled devices has trigged interest in the development of systems that will integrate WLAN and cellular wide area data network technologies such as WiMAX or Universal Mobile Telecommunications System (UMTS) with support for vertical handoffs between the different cellular networks [1]. Because of the demand for efficient mechanism, mobile users will be able to experience ubiquitous data services and very high data rates across heterogeneous networks by using WLANs as a complementary technology for next generation cellular data networks, while providing the end user continuous access [2].…”

The complementary characteristics of Worldwide Interoperability for Microwave Access (WiMAX) and IEEE 802.11 Wireless Local Area Network (WLAN) networks make them attractive for integration to offer the best of both technologies. However, in order to make the integration effective, the in-depth mobility study by simulation is necessary. This paper addresses the simulation models for mobility management procedures in an interworking of WiMAX and WLAN network for the various integration scenarios. The mobile multihomed node models of WiMAX and WLAN interfaces are developed and simulated in various traffic environments and network integration topologies including group mobility and MANET. The simulation results show that the developed models are useful for mobility studies in various integration wireless networks.

“…Tight coupling and loose coupling are two basic methods of cellular/WLAN integration. Although faster handoff is achieved in tight coupling architecture, it incurs design complexity and congestion in cellular network [5,7,8]. Other hand, loose coupling architecture will be more promising for next generation all-IP based heterogeneous network [9,10].…”

Demand for the Internet services through GPRS/3 G networks is proliferating day-by-day. But low bit rate puts constraints on multimedia or mobile business services. In contrast. Wireless Local Area Networks (WLANs) provide high bit rate with low deployment cost. Therefore, integration of these two complementary systems would be the focus of next generation wireless networks. However mobility and handoff management become the key issues for such integration. If a cellular operator deploys as Operator's IP network (OIN), it will be connected to GPRS at Gi interface and to the Internet through firewall. Alternatively, the Internet can be connected directly at Gi interface and OIN can be connected to the Internet. These connection mechanisms restrict on scalability due to large packet forwarding delay. In this paper, we propose a new way to integrate GPRS/UMTS, OIN and the Internet for better scalability and smaller packet delay. We deploy one gateway for users of cellular (GPRS/UMTS) and WLAN host. The gateway is in OIN and is connected directly with GGSN at Gi interface. The home agent functionalities are distributed in two level hierarchies within the OIN to reduce the packet and handoff delay. The proposed architecture would be useful for large network size.
