The development of wireless broadband access network (WBAN) leads to enhance the insufficiency of unoccupied radio resources. This is quite expected in coming times, wireless cellular technologies and wireless local area networks (WLANs) will work together in coexistence scenario within the alike unlicensed spectrums (USs). Although, two most emerging wireless networks, i.e., Long Term Evaluati...

Globally, the number of mobile broadband subscriptions is growing and the amount of mobile data traffic is expected to continue to grow rapidly. In the next five years the number of smartphone subscriptions is expected to more than double, while the amount of mobile traffic per active subscription per month of these subscribers is expected to nearly quadruple. As a consequence, mobile network o...

Voice over IP (VoIP) applications such as Skype, Google Talk, and FaceTime are promising technologies for providing low cost voice calls to customers over the existing data networks. Wireless networks such as Wi-Fi and WiMAX focus on delivering Quality of Service (QoS) for VoIP applications. However, there are numerous aspects that affect quality of voice connections over wireless networks. In ...

For the development of the 4G wireless networks the design of seamless and efficient Vertical handovers is an essential issue. Next generation wireless communications will likely rely on integrated networks consisting of multiple wireless technologies. So the integration of WiMAX with other wireless technologies, such as WLAN, Wi-Fi, UMTS or 3G, has attracted research community for the last few...

Wireless communication systems that consist of cellular, WLAN and Wi-Max access networks simultaneously are termed as heterogeneous wireless networks. Heterogeneous networks connect computers and other devices with different protocols. In the existing system the Greedy Approach was used for video transmission in heterogeneous network. It minimizes the video quality distortion by scheduling the ...

To provide uninterrupted service to all subscribers, we need to incorporate a low cost, flexible Heterogeneous network which can able to couple any kind of network for efficient spectrum utilization, hence improve system capacity. Therefore we have designed an integrated Wi-Fi, WiMAX network which provides high throughput, low end to end delay, flat and low jitter. Introduction Wireless communi...

Fiber-Wireless (Fi-Wi) is proposed as a hybrid access network (e.g. PON) with wireless access network (e.g. WMN) to provide high bandwidth, cost effective, and last mile internet access. It is powerful hybrid architecture of optimal backend and wireless front-end to support high data rates and throughput with minimum delay. This paper involves different types of optimizing algorithms which help...

Motivating students to learn Wi-Fi (wireless fidelity) wireless networking to undergraduate students is often difficult because many students find the subject rather technical and abstract when presented in traditional lecture format. This paper focuses on the teaching and learning aspects of Wi-Fi networking using limited hardware resources. It provides a walk-through tutorial on setting up Wi...

The development of health tele monitoring through wireless body area networks (WBANs) is an evolving direction in personalized medicine and home-based mobile health care. In a health tele monitoring system, a WBAN consists of a number of lightweight miniature sensors. The sensors measure physiological parameters such as electrocardiography (ECG), electroencephalogram (EEG), body temperature, an...

Urban access networks are the external part of worldwide networks that make telecommunication services accessible to end users and represent a critical part of the infrastructures of modern cities. An important recent trend in urban access networks is the integration of fiber and wireless networks, leading to so-called fiber-wireless (Fi-Wi) networks. Fi-Wi networks get the best of both technol...
