Implementação de uma arquitetura para o encaminhamento baseado no arcabouço Context-Aware Adaptive Routing Framework (CAARF)

Abstract

With the evolution of technologies, the number of users, devices and applications increases every day. However, even with the increase on bandwidth and transmission speed the resources available are not enough to ensure delivery and transmission quality of the packets. In order to meet the requirements of these new applications it is important to consider different aspects of the communication platform, such as traffic control, allocation and resources management, policing, admission control, scalability, among others. Currently, the traffic management of real-time applications is carried out based on quality of service metrics. However, given the emerging user’s and application’s requirements, such as mobility, flexibility, and larger demand of content, traffic management has become inefficient, taking the final user to be unsatisfied with the final delivery of content. The proposal of context-aware networks allows the mitigation of these problems turning data communication which is network oriented into a communication oriented to user’s and communication devices’ requirements and characteristics. The concept of context-oriented network is applied in this dissertation through the implementation of a solution for the context-aware adaptive routing, considering user’s, computational system’s and network resources’ behavior and expectations. Through this work it is possible to demonstrate that the implementation of context-aware networks allows the improvement of user’s experience and the optimization of network’s resources access.
