Recently wireless mesh network (WMN) has become popular especially for its low cost deployment in the areas of poor network infrastructure and terrain of difficult deployment. Although paths in WMN backbone network are stable, the access link contention can severely constrain the end-to-end throughput. We proposed an integrated routing system for WMN that(More)
This paper shows a full end-to-end WiFi-WiMAX network deployment in a testbed environment. It also demonstrates network integration of various wireless technologies that can be used by ISPs to provide services to large and small enterprise customers. The research indicates that WiFi-WiMAX deployment does not deteriorate throughput as compared to a(More)
Although cellular networks such as GPRS (2.5G) or UMTS (3G) have achieved both circuit switching and packet switching services with wide area coverage, they still fall short of meeting the high data rate demands of mobile users. Integrating cellular network with other high-speed and low-cost wireless technologies is a key challenge for migrating to 4G. The(More)
The access link contention can severely constrain the endto-end throughput of the path between a source and destination mobile node connected through the backbone of the Wireless Mesh Network (WMN). In this paper, we propose an integrated routing system for WMN that includes both the backbone paths and the ad-hoc paths formed as a result of direct(More)
As the wireless technology becomes more and more prevalent, the demand for it in the enterprise world grows to be more evident. The main objective of this test-bed environment research is to create a comprehensive and integrated WiMAX and Wi-Fi network and investigate the effects of WiMAX QOS routines on the throughput and delay time in the system. We(More)
Distribution of radio resources in fourth generation (4G) networks requires sophisticated Radio Resources Management (RRM) techniques to guarantee a sustainable level of Quality of Service (QoS) support. By analyzing the adaptive nature of the project applications and their traffic it is possible to substantially enhance broadband service delivery. In this(More)
