“…The GGSN based integration mechanism has been widely studied and suggested by several researchers in the literature (Tsao and Lin, 2002a;Benoubira et al, 2011;Varma et al, 2003;Altwelib et al, 2007;Altwelib and Ashibani, 2005;Tsao and Lin, 2002b;Buddhikot et al, 2003). When GGSN is the integration point, SGSNE or gateway is required to perform the internetworking.…”

To provide anywhere at any time services in an integrated wireless networking environment, seamless mobility is one of the most important and challenging issues. Recent literature shows that the seamless mobility can be achieved by performing significant modifications in existing network designs and protocol architectures. However, such intensive modification increases the network implementation complexity and deployment cost. In this study , we have proposed a Simple and Seamless Vertical Handoff Protocol (SSVHOP) to attain the seamless mobility without implementing any major modification in the existing network topology or protocol architecture. The foundations of the underlying principle of the SSVHOP are based on a proactive RSS handoff triggering mechanism and multi-homing capabilities of mobile terminal. In addition, SSVHOP reduces the signaling and processing cost of the network to achieve low handoff delay and packet loss during upward and downward vertical handoff scenarios. Moreover, it has been observed that the proposed design also improves the data session performance by routing the data packets on the optimal route and by introducing an overhead free mechanism for data transportation in an integrated UMTS/WLAN network. We evaluated and compared the SSVHOP with the tight coupling mechanism. By analyzing mathematical modeling and simulation results, it is evident that the SSVHOP performs better than the tight coupling mechanism for all tested applications and measurement parameters.

“…Loose coupling Approach for UMTS/WiMAX Integration by adaptive modulation technique in non-line-of-sight (NLOS) environments. Base stations of WiMAX can provide communication without the need of line-of-sight (LOS) connection [5]. Interworked WiMAX-3G Cellular Data Networks architecture for Mobility Management and Performance Evaluation by interworking environment and the service exibiity that this technology offers to the currently deployed wireless broadband technologies makes it appealing to users, service developers and network operators [6].…”

Wireless network is one of the wide areas of interest due to the advanced services they provide. As in the modern era, advanced technologies in wireless network are developing at a rapid rate so it is also necessary to increase the quality & services of them. Recently developed technology like 3G, Wi-Fi, WiMAX, LTE etc are widely used over the world and provides many varieties of services. This paper comparatively analyze the two advanced technology of wireless network: WiMAX and 3G network on the basis of several parameters like energy efficiency, QoS etc to evaluate their performance to find out which networks present the best services and advantages. The metrics used for performance evaluation are Average Jitter, Average Delay, Energy Consumption, Average Queue length, Signal Received with Errors, Total unicast data sent & received, Unicast received Throughput of the WiMAX and 3G network using QualNet 6.1 simulator.
