Three Dimensional Broadcast Protocol forWireless Networks

We present three dimensional broadcast (3DB) a wireless protocol designed for communication among nodes in three dimensional space. 3DB can be used for a large variety of applications, with static or mobile nodes. However, in this paper we apply 3DB for communications among airplanes, to show that the protocol performs very good even in such difficult conditions. On the other hand, communications among aeroplanes is an important application. In this scenario, 3DB enables the broadcast of emergency and surveillance information such as real time video over the network even in presence of adverse conditions, such as coordinated terrorist attacks, which might have disrupted other communication ways. 3DB is very robust. 3DB minimizes the number of retransmissions and therefore reduce the collisions, which could considerably delay transmissions and disrupt the communications during emergency situations. 3DB performs very well in highly dynamic ad hoc networks of airplane. We have evaluated 3DB through analysis and ns-2 simulations.
