Architectural and technical aspects for Ad Hoc Networks based on UTRA TDD for Inter-Vehicle Communication

چکیده
The CarTALK 2000 [1] project aims at the development of an Ad Hoc wireless network, which can be classified as fast moving outdoor network. Main characteristics of such a kind of network are the large and variable number of mobile terminals, an extremely dynamic network topology and stringent requirements related to broadcast warning messages. In order to satisfy the basic requirements of such a radio interface, the framework of the UMTS Terrestrial Radio Access Time Division Duplex (UTRA-TDD) with modifications has been adopted as target system in the CarTALK 2000 project. This paper introduces the architectural reference model of the communication system and discusses the main technical issues that arise when passing from a centralised network architecture (as the current UTRA-TDD communication system architecture) to a totally decentralised Ad Hoc mode.

متن کاملRR-ALOHA, a Reliable R-ALOHA broadcast channel for ad-hoc inter-vehicle communication networks
Ad-hoc networking is under evaluation for inter-vehicle communication architectures. In spite of the large existing literature, many problems generated by the peculiarity of this specific scenario are still unsolved. In this paper we present a novel MAC protocol, RR-ALOHA, able to guarantee a reliable single-hop broadcast communication in an ad-hoc network environment where the hidden terminals...
