Skype has been the most successful service provider and studying it may provide insights into possible solutions. A model has been proposed for further research that is not only user centered, but can also benefit from some of Skype’s attributes such as ability to interact with NATs and firewalls seamlessly.
Video conferencing is rapidly gaining momentum and many end users are adopting this service. For instance, skype is the fastest growing audio conferencing service provider with its annual revenue exceeding $ 136 million (Huang, Chen, & Huang, 2009). With the rapid growth and expansion witnessed in this industry, information technology experts are concerned with the impact of video calls, and the quality of experience under a variety of network conditions that are available to them. Skype offers its end users voice calls services, text messaging services, audio conferencing services, and instant messaging (Baset & Schulzrine, 2006). Delivering delay sensitive voice data from one user to user effectively has been a multimedia networking problem. Voice data has a high data rate. Failures in networks for example, impairments in network capacity significantly affects the voice traffic data rates. The rapid increase in multimedia traffic seen over the internet presents a major hurdle in delivery of quality service to end users. In order to deliver quality service, voice data has to be sent using a high bit rate. Using a higher bit rate could however result in the waste of network resources. Using a higher bit rate mat also result in congestion within the network. the aim is to guarantee quality of experience (QoE) the end users receive is high. However, using high bit rates would result in network congestion which would in turn compromise end user QoE.
In order to address this problem, studies have been conducted on skype to establish how it manages to deliver to its end users a high

The recent telecommunication trends have well influenced other sectors like business, education, and tourism with the emergence of e-commerce, online tutorials, and other web-based services. The remarkable feature of the broadband is that it connects people all over the world, and provides common populace with easy accessibility as DSL or cable modem at their homes.
WIRELESS NETWORKS COMMUNICATION. Wireless networking has advanced from a fascinating curiosity to an appealing technology choice for potential corporate users in all sectors of the economy. Successful test projects are helping an increasing number of institutions to make the shift towards major wireless projects.
The service accessibility of 4G LTE is expected to impose spectacular impact upon different mobile applications as well as service-provider competitions. This is owing to the reason of its effective featured services that include low latency and higher upload as well as download speeds among others.
Unfortunately, internet has become one of the ways that the thieves use to steal our personal and financial information. There are cases where unsuspecting customers have their user names and passwords hacked into by hackers who steal their credit card numbers and finally gain access to their money in various bank accounts and retirement funds.
The main aim is to maximize the use of internet services and the speed at which the internet connection operates in support of the communication across the wireless channels. The 4G wireless networks is expected to provide data access at approximately 85 percent in speed by statistics, above the initial network connectivity, to make it about sixty percent of daily average internet access in the United States.
The most recent version which is referred to 4G provides higher speed and faster communication as compared to 3G networks. The international standards recognized for mobile communication are regarded as 3G and 4G. The standards are used for specifying how the airwaves are utilized for broadcasting information which includes voice and data.
This is a transport protocol that is aimed at complete reliability but at the expense of delays whereas other protocols give better quality of service (QoS) at the cost of reliability. Some applications are better at taking delays in transmission rather than
ny data communication process, at least three elements such as information source, information transmission channel, and an information destination are key. However, circuit switching and packet switching are the only two key types of data switching (Benedetto S., and Biglieri
Low energy adaptive clustering hierarchy (LEACH) is mainly designed for the sensor networks in cases where the end user intends to remotely monitor and control the environment. Its main goal is to lower
