“…This study also presents a TPMS module for in-tire pressure monitoring. There are two distinctive differences: (1) The study in (Flatscher et al, 2010) makes use of a scavenging unit which converts vibration into electrical energy. By using an electromagnetic harvesting interface, as it is done in this study, no motion is required to power the sensor module.…”

Problem statement:This study presents a wireless sensor node dedicated for in-tire pressure and temperature monitoring. Additional features set it apart from the many different systems available on the highly competitive market. State-of-the-art implementations are mounted on the rim of a tire. Here the sensor node will be mounted on the inner liner of the tire. By moving the sensor node from the rim to the inner liner, new challenges in the analog design arise. Approach: To implement this sensor node new power supply methods are investigated. Next, analog designs with the focus on low power are developed. Since the sensor node is operated in a harsh environment, robustness is a key issue. Results: The discussed sensor is capable of either active or passive communication. The passive communication is used in the field of Radio Frequency Identification (RFID), whereas active communication is used to transmit the sensor data. A combination of both is also possible. To supply the chip in the tire an RF energy harvesting interface is implemented. An input sensitivity of -19.7dBm for the harvesting interface and -12.5 dBm for the RFID interface is measured. The on-chip temperature sensor consumes 4µA including the analog to digital converter. Conclusion: Choosing the discussed sensor node for in-tire monitoring enables new fields of applications. With this sensor node sensing additional parameters like road condition is possible. Using passive communication improves warehouse management for tire manufactures. Also, tire type identification at the car is enabled.

“…Such a basic confi guration may further be packaged on the micro-chip or even organized at wafer level, with increasingly capable systems and subsystems as required for a complete sensor system. An example of innovative wafer-level packaging, or so-called '3-D integration', of the physical layers needed for extremely small nodes in future wireless sensor networks (WSN) is described in some detail in Flatscher et al (2010). The required physical layers of a node in a WSN will typically include those illustrated also in the e-CUBES concept shown in Fig.…”

“…With this additional information, the coordinator is able to check, if the request is received in the correct GRS and from the correct node before confirming the reservation. It is worth mentioning that the performance of the GRS reservation method can be increased, if the used RF-transceiver device (physical layer) is optimized for fast start-up and frame synchronization, such as described in [13].…”

Wireless communication in a car has several advantages, given that demanded safety and real-time requirements are fulfilled. This paper presents a wireless MAC protocol designed for the needs of automotive and industrial applications. The proposed MAC protocol provides special support for network traffic prioritization in order to guarantee worst-case message delays for a set of high-prioritized nodes. The performance is further analyzed with a network simulator and compared with the IEEE 802.15.4 standard CSMA/CA protocol.
