To this date, Wireless Sensor Networks are still largely characterized by non-intensive applications, which means that they are mainly used to gather relatively small amounts of data. This project aims at pushing the limits of Sensor Networks to the point of transmitting video in real-time. The crucial advancement that enabled this application was the introduction of Time-Synchronized Channel Hopping which made communication more robust on unreliable wireless links. In addition to using the camera as a sensor, this project is concerned with interfacing smartphones with low power wireless devices. This fast way to test the network and interact with individual motes was put to the test by collecting sensor data (the images in this case) and displaying it on a smartphone. Additionally, smartphones capabilities such as tilt sensors and touch screen control can be used to operate vehicles such as helicopters and cars that are connected to wireless devices.
