Fading and obstacles constitute major threats to effective quality of service (QoS) delivery in wireless local area network (WLAN) environments.
In this contribution, we investigate the signal quality of indoor and outdoor WLANs over a defined coverage area. We present…

At present there are different TCP versions providing different performances. In this work the three of them: Reno, CUBIC and Vegas are considered. We simulate a WAN type network analyzing the throughput and performance of these TCP variants in order…

Based on the need to update the language and tools used to teach Procedural Programming during the first year of computer science careers, a cross descriptive research was conducted by assessing different programming languages.
The analysis involved a total of…

To support multimedia applications, it is desirable that an ad hoc network has a provision of Quality
of Service (QoS). However, the provision of QoS in an ad hoc network is a challenging task due to its
inherent…

The Web Accessibility Initiative (WAI) defines the guidelines to facilitate access for people with disabilities to ICT. This article presents a proposal to promote the unification and improvement of the works of two authors, combining the procedures and considerations after…

The introduction of mobile wireless devices brings unique challenges for distribution of data to many devices simultaneously. An optimizing multicast methodology called Probabilistic Multicast Trees (PMT) is extended to handle mobile wireless devices. We will show that PMT multiple tree…

This dissertation formalizes a comprehensive approach based on compiler technology [3-5] to simulate some basic forms of automata viz., finite accepters, finite transducers, pushdown accepters and Turing machines. These basic forms of automata are known for their simplicity and generality,…
