Some situations call for the creation of Mobile Ad hoc Networks (MANETs) because the devices in the network are moving very quickly. For example, military and emergency-response situations require MANETs. Unfortunately, having the nodes of a network rapidly changing direction makes it difficult for them to efficiently transmit information. In the time it takes to transmit a signal after the closest node is identified, the nodes may have moved apart. Researchers at North Carolina State University have developed an algorithm to address this issue.

Instead of having the transmitting node just identify the nearest node at the time, and hoping the closest node will still be in range when transmission starts, the algorithm determines which node will be closest when the transmission starts. The algorithm also determines how quickly the information should be transmitted. If the transmission is too fast, the data can be corrupted, and if the transmission is too slow, there is a loss of efficiency.
