- Collision warning system for connected cars
- In the European Union alone, more than 40,000 people die every year in car accidents. Even if alcohol abuse or excessive speeds are certainly the major causes of these accidents, many crashes could be avoided if collision avoidance systems CAS were used. Such systems have been developed by researchers working...

- An Experimental Study on the Capture Effect in 802.11a Networks
- In wireless networks, a frame collision does not necessarily result in all the simultaneously transmitted frames being lost. Depending on the relative signal power and the arrival timing of the involved frames, one frame can survive the collision and be successfully received by the receiver. Using the IEEE 802.11a wireless...

- Scalability Analysis of Rate Adaptation Techniques in Congested IEEE 802.11 Networks: An ORBIT Testbed Comparative Study
- Recent real-world measurements in dense congested radio environments have pointed out the inefficiency of frame error-based bit-rate adaptation mechanisms, which significantly reduce network capacity by misinterpreting frame errors due to collisions. These effects are likely to be amplified with the heavy use of media applications. Fortunately, traditional SNR-based rate adaptation,...

- On Scheduling and Real-Time Capacity of Hexagonal Wireless Sensor Networks
- Since wireless ad-hoc networks use shared communication medium, accesses to the medium must be coordinated to avoid packet collisions. Transmission scheduling algorithms allocate time slots to the nodes of a network such that if the nodes transmit only during the allocated time slots, no collision occurs. For real-time applications, by...
