Dual band centralized Ad-hoc Network Architecture (CANA) definition

Concerning the layer 2: a novel Centralized Ad-hoc Network Architecture (CANA) was proposed in order to allow for the coexistence of a short range ad-hoc mode of operation under the umbrella of the traditional WLAN cell (HiperLAN/2 in particular). This new architecture includes all adhoc algorithms comprising node discovery and route as well as dual mode of operation between 5 and 60GHz comprising related DLC and CL enhancements.

It has been verified that these DLC extensions allows a seamless operation between 5GHz (in a TTD/TDMA centralized mode) and 60GHz (using a centralized clustered architecture with Neighborhood discovery and adhoc routing) with reasonable overhead.

As a result of these studies an entire software platform based on the Network Simulator tool integrating all the CANA modules has been implemented and is usable for detailed performance assessment.

The development, evaluation and testing of the new dual-mode MAC layer, the required Neighborhood Discovery process and the interactions with the upper layer have been performed. The goal of integrating the ad-hoc concept at 60 GHz into the standard HIPERLAN/2 system by providing for the concurrent operation of the AP at a 60 GHz cluster has been achieved. In this way, it was shown that MTs may take advantage of the total capacity increase by using the shorter-range and more vulnerable 60GHz paths under the appropriate adjustment of the developed algorithms.
