Dynamically distributed network control for message dissemination in ITS

Abstract

We propose D2-ITS, a flexible and extensible framework to dynamically distribute network control to enable message dissemination in Intelligent Transport Systems (ITS). By decoupling the control-from the data plane, D2-ITS leverages network programmability to address ITS scalability, delay intolerance and decentralization. It uses a distributed control plane based on a hierarchy of controllers that can dynamically adjust to environment-and network conditions in order to satisfy ITS application requirements. We demonstrate the benefits of D2-ITS through a proof-of-concept prototype using the ns-3 simulation platform. Results indicate lower message delivery latency with minimal additional overhead.

Handover and Load Balancing for Distributed Network Control: Applications in ITS Message Dissemination

“…As previously pointed out, in [8], we propose D2-ITS, a novel dynamically distributed network control plane framework and show how it is able to support ITS' Road Hazard Warning (RHW) message dissemination application.…”

“…In [8], we demonstrated that by decoupling the controlfrom the data plane, D2-ITS leverages network programmability to address ITS scalability, delay intolerance and decentralization. In this work, we extend D2-ITS with handover and load balancing capabilities in order maintain continuous service availability and satisfy application quality-of-service requirements when subject to conditions such as unpredictable mobility patterns of fast moving vehicles, communication channel impairments, etc.…”

“…To achieve seamless handover in D2-ITS, we included the following extensions to D2-ITS's original design (as described in [8]):…”

“…However, logically centralized control function or static control distribution are not compatible with VANET's scalability, geographic distribution, administrative decentralization, and diverse qualityof-service requirements. In [8], we propose the Dynamic Distributed Network Control for ITS, or D2-ITS, a flexible and dynamically distributed network control framework, which aims at addressing the scalability, heterogeneity, delay intolerance, and decentralization requirements of ITS applications. To this end, D2-ITS' distributed control plane: (1) is decoupled from the data plane, and (2) is based on a control hierarchy that can dynamically adjust to current environment and network conditions in order to support ITS application requirements.…”

“…It is worth noting that the applications considered in our work are commercial or entertainment related, while the safety or emergency related services are not addressed by our protocol in view of their high reliability and time constraint requirements. Actually, for those safety-related applications, the most feasible solution is direct broadcasting, including CAM (Cooperative Awareness Messaging), DENM (Decentralized Environmental Notification Messaging) and BSM (Basic Safety Messaging) etc [4].…”
