As vehicles become intelligent for the convenience and safety of drivers, in-vehicle networking (IVN) systems and smart modules are essential components of intelligent vehicles. However, there are obstacles for the wide acceptance of smart modules. First, there exist numerous IVN protocols that a smart module should be able to support. Second, the whole smart module has to be replaced when only the sensor of the module fails. In order to overcome these obstacles, a smart module is implemented as two units; one responsible for network communication and the other for sensor/actuator operations. In addition, the modules use an interface between the two units as defined by the IEEE 1451 standard. This paper presents a design of the smart module based on the IEEE 1451 standard along with the experimental evaluation for time delays.
"An implementation of additional IEEE 1451 features often requires the use of a separate microcontroller or a processor on the TIM (consider, e.g. Lee et al. (2004) and Ross et al. (2009)). Needless to say, these can significantly increase the price and power consumption of the resulting P&P sensors, which is especially undesirable for WSN. "
[Show abstract][Hide abstract] ABSTRACT: The ability to connect sensors to the Wireless Sensor Network WSN nodes without the need for physical device configuration has many advantages: application development is simplified, network deployment and service is easier, and sensors can be swapped or added on-the-fly. The existing solution for sensor Plug-and-Play P&P for WSN nodes is the IEEE 1451 set of standards developed for smart transducers. The serious drawback of this solution is that it cannot be used with the most widespread plain transducers without adding multiple external components. Therefore, in this paper, we introduce a novel mechanism that allows implementation of P&P connection to WSN nodes for commercially available off-the-shelf sensors with the most widespread wired plain digital interfaces SPI, I2C, 1-wire etc. without any single external component utilisation.

"The low–level module of a WSN normally provides computing capability and data processing that offers direct access or remote control functions. The concept and design methodology of smart transducers that adhere to IEEE 1451 has been recently proposed for IVN systems , . IEEE 1451 provides an open platform for the development of networked electronic modules using different physical links. "

The Smart Transducer concept -along with IEEE Standard 1451- improves the scalability of these networked electronic devices into a vehicular system. This paper describes the design and implementation of a real-time environmental wireless sensor network that characterizes air quality in Asuncion, Paraguay. Mobile sensor devices in public transport vehicles provide an effective mechanism to develop an efficient solution for this characterization. The development of the sensor network is presented, and experimental results obtained for the characterization of the proposed environmental monitoring system are provided.

[Show abstract][Hide abstract] ABSTRACT: The smart transducer interface described by IEEE 1451 standard provides precision, single chip solution at low cost for smart systems. Transducer Interface Module (TIM) of the IEEE standard is designed to provide smart readout for transducers.
