Near-Term Digital Radio (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Near-term digital radio (NTDR) program provided a prototype mobile ad-hoc network (MANET) radio system to the United States Army. The MANET protocols were provided by Bolt, Beranek and Newman; the radio hardware was supplied by ITT. These systems have been fielded by the United Kingdom as the High-capacity data radio (HCDR) and by the Israelis as the Israeli data radio. They have also been purchased by a number of other countries for experimentation. The NTDR protocols consist of two components: clustering and routing. The clustering algorithms dynamically organize a given network into cluster heads and cluster members. The cluster heads create a backbone; the cluster members use the services of this backbone to send and receive packets. The cluster heads use a link-state routing algorithm to maintain the integrity of their backbone and to track the locations of cluster members.
