Time-bound single-path opportunistic forwarding in disconnected industrial environments

摘要

Vehicular ad hoc networks have enabled applications for real-time data sharing such as safety and infotainment services in smart cities. Notably, with the widespread adoption of the internet of things (IoT), the back-end networks are not designed to carry large amounts of data as it leads up to network congestion and consumes a significant amount of energy. Moreover, the IoT sensor data requires real-time transmission for efficient decision making, especially for safety-related warning messages. Often a greedy approach is usually adopted to select the next-hop vehicle near the destination node; however, without considering the direction, the performance degrades. In this paper, we propose a vehicle-based real-time data transfer framework using a path-aware dissemination scheme. The messages are forwarded to vehicles on the road segment leading up to the destination. We compare the proposed scheme to traditional methods like flooding, random vehicle selection, and distance-based techniques. The results demonstrate that the proposed path-based technique increases the success rate with a minimum number of intermediate hops. (C) 2020 Elsevier Inc. All rights reserved.
