We’re pleased to announce two new Executive Members of the NS-3 Consortium: the Centre Tecnològic de Telecomunicacions de Catalunya (CTTC) and the INstituto de Engenharia de Sistemas e Computadores do Porto (INESC Porto). Both institutions have a strong history of supporting ns-3 over several years. CTTC, in partnership with Ubiquisys, has led the development of the ns-3 Long Term Evolution (LTE) simulation model, and the Telecommunications and Multimedia Unit at INESC initially funded Gustavo Carneiro’s ns-3 development activities, and continues to perform wireless research involving ns-3. The Steering Committee will expand to include Dr. Nicola Baldo (CTTC) and Prof. Manuel Ricardo (INESC).
