TSCH Evaluation under Heterogeneous Mobile Scenarios

Performance Evaluation of Heterogeneous Network Scenarios

Packet loss, delay and jitter degrade the quality of services like VoIP (Voice over IP) or Video Streaming over IP networks. In real networks, an experimental measure of these parameters is fundamental in the planning process of new services over novel network infrastructures. Furthermore, currently networks are complex heterogeneous systems (in terms of access network technologies, end-users’ ...

Evaluation Framework for Dependable Mobile Learning Scenarios

The goal of the dependability analysis is to predict inconsistencies and to reveal ambiguities and incompleteness in the designed learning scenario. Evaluation, in traditional learning design, is generally planned after the execution of the scenario. In mobile learning, this stage becomes too difficult and expensive to apply due to the complexity and heterogeneity of mobile infrastructure with ...

User evaluation of mobile augmented reality scenarios

Augmented reality (AR) technologies are becoming state-of-the-art in the mobile technology domain. However, developing successful end user services around AR is still in its infancy, which is partially resulting from the lack of user research regarding potential users’ expectations and user acceptance in the particular area. In order to identify the most potential use cases and contexts, in whi...

An Evaluation of Mobile End Devices in Multimedia Streaming Scenarios

This paper compares handhelds based on the iPhone and Android operating systems in multimedia streaming scenarios. We simulate typical Internet network impairments, i.e. packet delay and packet loss, and evaluate their effects on the end devices. Additional evaluations include bandwidth overhead inflicted by the different streaming approaches and traffic shape and fairness when both handhelds c...
