Unmanned Aerial vehicles (UAV), more commonly known as drones, are widely used by military and civilian applications. They can be used for remote sensing, transportation, scientific research, armed attacks, search, and rescue. They can be used in applications where human presence is dangerous. Drones could be equipped with cameras, sensors, communications equipment, and weapons. UAVs can be piloted by a human from land or can be autonomous. In the future, autonomous UAVs will work collaboratively with other aircrafts. UAVs can communicate wirelessly, forming a MANET. Thus the constraints and advantages of MANETs are transferable to networks of UAV. This paper presents some networking protocols for the UAV wireless networks.
