Car-based data collection for low energy devices

Abstract : In smart cities, the mobility of vehicles can be utilized to collect data produced by connected objects in the environment. In the convergence between the Vehicle-to-Everything (V2X) communications and the Intelligent Transportation System (ITS) vision, several ITS infrastructures will be available to assist in the data delivery to the central server. With the unique data collection environment in place, a routing protocol needs to be developed to utilize all the components efficiently. In this thesis, our main research question focus on whether a simple and efficient Vehicular Delay Tolerant Networks (VDTN) routing protocol for delay-tolerant applications can be designed and achieves high performance with the ease of adoption and standardization in mind. Here, we present and evaluate a simple and efficient hierarchical VDTN routing protocol named DC4LED and compare its performances to the benchmark routing protocols. The evaluation shows comparable performances of the DC4LED to the Epidemic routing protocol, as the upper benchmark, in its probability of data delivery and average latency. The DC4LED displays a critical advantage in maintaining a low network overhead over an increasing number of vehicles in the network, highlighting its efficiency and implementation scalability. We also extend the DC4LED routing protocol, which adopts the limited multi-copy forwarding strategy for a denser data collection network to reduce the delivery latency further as the vehicular network grows. Our overall results show the high performances of our proposed strategy for delay-tolerant data collection in smart cities. It also indicates that the complexity of existing VDTN routing protocols is not necessary for the envisioned services.
