摘要: The intelligent transportation systems (ITS) use advanced communications and control technologies to improve current systems. To achieve many ITS applications, the ability exchange messages between vehicles is necessary. This generally required as inter vehicle communication (IVC). IVC can be considered a special case of ad hoc networks, where nodes only move along predefined road paths. We propose new broadcast protocols that make global positioning system (GPS) information enhance performance service in IVC. efficiently necessary for any (e.g, updating routing tables, etc). two algorithms effectively reduce number re-broadcast without affecting hosts (vehicles) receive broadcast. simulation results show up several hundred percentage bandwidth utilization improvement achieved by our proposed protocols.
