Abstract: An Ad-Hoc wireless network according to the present invention employs a TDMA based neighbor discovery protocol, where each network node is assigned a unique time slot to broadcast neighbor discovery packets or messages. A primary controller node is dynamically designated to perform the time slot assignments. A dynamic selection of a secondary or backup controller node is further provided in case of failure of the primary controller node. The present invention further includes flooding techniques based upon TDMA. A TDMA HELLO flood is used to distribute a small number of common parameters to network nodes by placing or piggybacking the information within the neighbor discovery messages. A CNR flood is based on the principles of a RAKE type receiver and used to distribute time slot assignments to the entire network.

Abstract: The present invention protocol offers guaranteed Quality of Service (QoS) for concurrent calls in a highly dynamic, scalable network. The invention employs a TDMA reservation technique to transmit voice traffic to multiple destinations and a CSMA/CA contention scheme to support data traffic. The present invention operates over a link-state based routing protocol that reliably floods routing and resource reservation information to network nodes. The present invention is suitable for general networking applications that require QoS for multimedia traffic in a mobile, Ad-Hoc network and enables conference calls to be established and operated in that type of network under various conditions. Moreover, the present invention capitalizes on certain properties of a radio, such as a RAKE type receiver, that sums up multiple, identical transmissions from multiple sources. In addition, the present invention enables roaming between and/or within a group or island of network nodes during the lifetime of a call.
