In wireless networks, trying to avoid interferences by using allocation and scheduling techniques is not an effective and permanent solution. In a high density network where nodes can have a large communication range, the channel capacity can be insufficient to support all broadcast messages even if they are perfectly scheduled. This is the case of the control channel (CCH) in the IEEE 1609.4 standard...
Vehicle Ad-Hoc Networks was developed in order to improve the safety and comfort while driving a car. Thereby, IEEE 802.11p and IEEE 1609.4 are used for this purpose. However, these protocols showed some limitations, and this is showed through the low probability of successful transmission for safety messages and through the low throughput achieved for service messages. This paper proposes new mechanism,...
The following paper discusses the design and implementation of a 3D gesture-based control system that can substitute any complex human-machine interface with a simpler and more familiar one. This system that can be used by any user disregarding his/her background (age, education, health, language etc.…), making it dependent on nothing more than the movements of the user’s hands, thus allowing them...
This paper, represents a design constituting of a robot that uses an Arduino to drive motors enabling it to move around the room in a direction determined by a Processing sketch that uses the Kinect to scan the room and determine where the robot should move. The design works by tracking the center of mass of a human having a skeleton, and avoiding obstacles that interfere it`s movement. The approach...
