ITS-based decision making mechanism for opportunistic networking in heterogeneous network environment

Rodrigo Silva 1, 2
Abstract : Demand from different actors for extended connectivity where vehicles can exchange data with other devices have pushed vehicle manufacturers to invest in embedded solutions, which paves the way towards Cooperative Intelligent Transportation Systems (C-ITS). Cooperative vehicles enable the development of an ecosystem of services around them. Due to the heterogeneousness of such services and their specific requirements, for ubiquitous connectivity it is necessary to combine existing wireless technologies, providing applications with a communication architecture that hides such underlying access technologies specificities. Moreover, due to vehicles’ high velocity it is needed a Decision Maker (DM) mechanism capable to take into account the short-term prevision about network environment in order to better manage all flow communications. Based on the Intelligent Transportation Systems (ITS) architecture proposed by International Organization for Standardization (ISO), we proposed the Ant-based Decision Maker for Opportunistic Networking (AD4ON), a modular decision maker mechanism capable to choose the best available access network for each data flow in an heterogeneous and dynamic network environment. The proposed mechanism manages requirements and preferences from different actors, taking into account the short-term prevision about the network environment. Simulations have demonstrated that the AD4ON outperforms current benchmark algorithms, by increasing decision’s stability, reducing the “ping-pong” effect and maximizing flow’s satisfaction. Moreover, we demonstrate that taking into account the short-term prevision, the AD4ON can optimize the algorithm reaction time.
