As we move towards the next generation networks, one of the fundamental issues to consider is the integration of wireless technologies. Integrated networks will have impressive capabilities as well as cumbersome challenges in areas such as Radio Resource Management (RRM), Quality of Service (QoS), Security, Mobility, and Power Management. In this paper, we tackle one of the challenges facing researchers and developers in this area. The main objective of this research was to build an integrated WiFiWiMAX network in a test-bed environment, and to investigate the effects of integration on the QoS performance. This study is based on practical deployment and measurements in a laboratory environment. We successfully implemented an integrated system and experimented with various QoS scenarios. A set of RRM schemes were defined for the integrated networks and actual results collected from network analyzer showed that the QoS requirements were met throughout the WiFi-WiMAX networks.

“…WiMAX base stations can serve as wireless backhauls where the bandwidth of WiMAX networks is shared by Wi-Fi hotspots to provide Internet connectivity to mobile Wi-Fi users (Fantacci & Tarchi, 2006;Lin, Lin, Chang, & Cheng, 2009;Huang, Hu, Chen, Chen, & Chen, 2010). From the aspect of practicability, the integration of Wi-Fi and WiMAX can benefit Wi-Fi service providers because the cost of wired infrastructure can be avoided.…”

Several emerging studies have focused on the pricing issue of bandwidth sharing between Wi-Fi and WiMAX networks; however, most either concentrate on the design of collaborated protocols or figure out the issue without the overall consideration of consumer preferences and contract design. In this study, we explore a wireless service market in which there are two wireless service providers operating Wi-Fi and WiMAX. One of the research dimensions given in this study is whether wireless service providers implement bandwidth sharing, while the other is whether they make decisions individually or jointly. By involving consumer preferences and a wholesale price contract in the present model, we find that bandwidth sharing would benefit a WiMAX service provider, yet a Wi-Fi service provider would make no significant savings under a wholesale price contract. In addition, the profit of a WiMAX service provider may increase with Wi-Fi coverage when bandwidth sharing has been implemented but decrease with Wi-Fi coverage when both wireless services operate without bandwidth sharing. Furthermore, the WiMAX service provider allocates more capacity when the average usage rate increases, but lowers the expenditure of capacity when the average usage rate is too high.

“…In [12], an integrated architecture utilizing a novel WiMAX/WiFi access point (W 2 -AP) device was proposed to effectively combine the WiMAX and WiFi technologies, where the protocol operation of the WiFi hotspots is the same as that of the WiMAX system, and thus the WiFi network can support connection-oriented transmissions and QoS in a similar fashion to the WiMAX system. In [13], the application of integrated IEEE 802.16/802.11 broadband wireless access technologies was investigated along with related protocol issues for telemedicine services.…”

Performance Modeling of an Integrated Wireless Network Using WiMAX as Backhaul Support for WiFi Traffic

We propose an analytic model for an integrated wireless network using WiMAX as backhaul support for WiFi traffic and evaluate the system performance. A unique feature for the proposed model is that the WiFi traffic completely reflects the realistic user mobility. A WiFi call can be overflowed to its overlaid WiMAX cell when it is rejected at the WiFi cell; a WiFi call may also work for some period of time in the WiFi cell and then make a vertical handoff to its overlaid WiMAX cell when it wants to move from its current WiFi cell (e.g., office) to its target WiFi cell (e.g., airport). Further, the target WiFi cell may be located at another place in the same WiMAX cell, or at a different WiMAX cell. We use Markov processes to model the dynamics of the WiMAX traffic and WiFi traffic including the overflowed WiFi traffic, the vertical handoff WiFi traffic, the horizontal handoff WiFi traffic, and the take-back WiFi traffic. We derive the explicit expressions of various traffic arrival rates and performance metrics and analyze the performance improvement of the WiFi traffic and the impact on the WiMAX traffic due to backhaul support. Numerical results are provided for further understanding of the gain and loss of the integrated architecture.
