The motivation behind SMART-Net is to overcome the limitations of conventional Broadband Wireless Access systems, in which all communications are required to pass through one costly central base station. Therefore, the project proposes a novel system architecture enabling next generation of Wireless Mesh Networks which will support new applications by the Internet, innovative service packages delivery offered by telecom operators and advanced communication solutions for public safety and homeland security.The SMART-Net concept is based on a decentralised vision in which access infrastructure is partly distributed across the network, allowing reduction of service cost and significant increase of performance. To this end, smart antennas, traditionally deployed in base stations, are provided for use with each subscriber unit. The ability to combine efficiently these new capabilities with mesh networking will allow the system to support scalability, reliability and security. This approach is strengthened with advanced routing and scheduling protocols specifically designed for heterogeneous Wireless Mesh Networks.A key objective of the project is to make available comprehensive and configurable experimental facilities for investigation of future wireless networks. This is achieved by deploying simulation and real-life Testbeds based on advanced Radio Access Technologies. Assessments of the proposed solutions are intended to be conducted in a large-scale environment, interconnecting the real and virtual Testbeds, thereby merging both real and simulated worlds. Moreover an open-access is provided for use by external entities and potential federations with other Testbeds.
