This paper presents the Genetic Algorithms (GA) as an efficient solution for the Okumura-Hata prediction model tuning on railways communications. A method for modelling the propagation model tuning parameters was presented. The algorithm tuning and validation were based on real networks measurements carried out on four different propagation scenarios and several performance indicators were used. It...
In this paper a new pedestrian mobility model for outdoor scenarios is presented. It captures realistic features like moving-in-groups, conscious traveling and smart traveling. The routing algorithm proposed within the model works under a step by step approach, leading users to their destination while, at the same time, using more attractable streets from a pedestrian point of view. The model concept...
