the intelligent transportation system (its) provides wireless and mobile communication between vehicles and infrastructure to improve the safety of transportation and make the journey more enjoyable. this system consists of many fixed and mobile nodes (vehicles, trains, vessels, air planes), wireless and wired telecommunication technologies to exchange information between mobile nodes or betwee...

In this communication, a low-cost circularly polarized wire antenna exhibiting improved gain performance for Dedicated Short Range Communications (DSRC), vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications is presented. The proposed antenna comprises a Y-shaped quarterwavelength monopole antenna surrounded by two iterations of eight conductive arched walls acting as para...

Development and projections of wireless PDAs enable to envisage the design of new application classes that exploit short range and direct communications (e.g. one-hop communications). In a close future we may imagine mobile users dynamically and spontaneously exchanging information as soon as they are close enough. In such a context, a connection between two nodes may be broken at any time beca...

Fig. 1. Inter-chip wireless communication within computer chassis Impulse radio systems have received much attention as a possible architecture for UWB transceivers due to the large data bandwidth, low spectral interference with nearby channels, and simplicity of UWB transmitter/receiver architectures using mostly digital implementations. Due to the low emitted power spectral density of -41.3dB...

Ultra-wideband (UWB) has received significant attention for applications in target positioning and wireless communications recently. The extremely short pulses in turn generate a very wide bandwidth and offer several advantages, such as large throughput, covertness, robustness to jamming, lower power, and coexistence with current radio services. UWB not only can transmit a huge amount of data o...

The traditional, centralized, approach to supervision is challenged when communications between supervision and supervised systems become either slow, disrupted or too costly. To obtain a supervision system that is able to dynamically adapt itself to the communications’ state, we propose to distribute the supervision process through several autonomous agents. To evaluate our approach, we made e...

Product standards have become increasingly important due to increased technological complexity. A barrier to implementing intelligent transportation systems (ITS) technologies has been the development of compatible products and systems. Telecommunications infrastructure has been considered one of the core elements of ITS. Relevant communications options include wireline, wireless and dedicated ...

This paper is concerned with the problem of measuring market response to a "communications mix" -the various means which a firm employs to transmit sales messages to potential buyers. Distributed lag models are applied to time series data for an ethical drug to estimate the short-run and long-run effects on market share of expenditures made for journal advertising, direct mail advertising and s...

In this work we introduce a new model for exploiting network diversity in vehicular environments, which integrates ad-hoc communications with the existing cellular infrastructure aiming to meet the diverse communication requirements of vehicular applications. Although there are a plethora of reported studies on either 802.11p Digital Short Range Communications (DSRC) or cellular networks, joint...
