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 i...


What is claimed is: 1. A wireless communication unit to transmit and receive information within a mobile, ad-hoc wireless communications network, including a plurality of wireless communication units arranged into first and second tiers, and to conduct a conference call with at least two other communication units within said network, wherein said first tier arranges said plurality of communication units into a plurality of groups without communication units being common between said first tier groups, each first tier group being associated with at least...
