Abstract

This deliverable presents the final version of the specification for the mechanisms included in the Wi-5 Access Points (APs), which have been developed within WP3 of the Wi-5 project. Coordinated by a controller, these APs are able to run the Smart Access Point Solutions including resource management algorithms such as dynamic channel allocation, load balancing and power control. The seamless handover is also an important functionality to support this and the integration with the coordination entities of the Wi-5 architecture (i.e., the Wi-5 controller) and the interface with performance monitoring mechanisms are also defined. The document also includes a series of simulations aimed at studying the possibility of performing a centrally controlled coordination of the frame aggregation functionalities available in 802.11n and 802.11ac. The main section of this deliverable (section 4) is devoted to explaining the final version of the functionalities enabling all the Wi-5 features, with detailed information about their implementation, and the advances with respect to previous versions reported in Deliverables D3.2 and D3.3. These functions rely on the monitoring mechanisms defined in Deliverable D3.1. This section includes a) The framework used for the implementation based on the use of Light Virtual APs (LVAPs). b) The horizontal handover scheme, integrating multi-channel APs with the LVAPs approach, which includes extensive tests of the handover latency illustrating that they can really be seamless. c) Different applications including Channel Assignment, Mobility Management (in a reactive and a proactive way), and Load Balancing based on Received Signal (RSSI), Fittingness Factor and also considering the services being run in the terminals. Another section (section 5) details the results of a battery of measurements of the delays incurred by the system. Finally, a simulation environment is used in order to test different ways of performing a coordinated control of the frame aggregation mechanisms of 802.11. A Conclusions section surveys the work that has been carried out. The most innovative aspects are: a) The development of a method able to proactively manage the mobility of the users, also combining this with load balancing in real time. b) The proposal of central coordination for frame aggregation, which can provide a significant improvement in efficiency while still respecting the real-time requirements.
