Project: Gestão de Mobilidade Centrada no Utilizador Final

Acronym: UMM
Main Objective: The work to be developed in this project relates to the topic of global mobility management in spontaneous wireless environments, i.e., environments that self-adjust to any network topology change. Global mobility management is addressed from a network perspective, and the purpose is to ensure a transparent access to Internet services (e.g Triple Play) for the end-user, who will be able to access his/her subscribed services independently from access attachment point, location, and based upon his/her own requirements (“Quality of Experience”, QoE). In addition, global mobility management is to be analyzed from a de-centralized perspective, given that environments to be considered will incorporate wireless local-loops that are based upon end-user willingness to cooperate. Main aspects to focus upon are:

1. Handover management optimization
a. Consider QoE as well as available (aggregated) spectrum to provide the user with the best possible connection seamlessly at any time and independent of location, having in mind user expectations.
b. Analyze and validate adequate cost functions and metrics to estimate QoE levels on-the-fly.
2. User-centric mobility management
a. Investigate and validate algorithms for a self-organized selection of anchor-points, aiming to insure system robustness to highly frequent changes.
b. Devise a global mobility management mechanism taking into consideration the aspects analyzed in relation to handover optimization and incorporating mobility models that support adequate anchor point selection.
