1. A server terminal configured to operate in an ad hoc cluster of terminals, comprising:

  • a user interface configured to transmit and receive communications during a call with a first terminal connected to an ad hoc network backbone of an ad hoc network, the ad hoc network comprising a plurality of clusters, each of the clusters comprising at least two piconets and at least one gateway terminal, each gateway terminal configured to form a communications link between at least two of the plurality of clusters, each of the piconets comprising at least one intra-cluster bridge terminal, a master terminal, and a member terminal slaved to the master terminal, and the intra-cluster bridge terminal being a member of the two piconets and configured to form a communications link between the two piconets;

    a processor configured to support an inter-cluster call between a second terminal in a first ad hoc cluster and a third terminal in a second ad hoc cluster by establishing a route on the network backbone for each communication packet transmitted from the second terminal to the third terminal, the route selected from a plurality of routes depending on whether the inter-cluster call is a first type of call or a second type of call that is different from the first type of call; and

    the processor further configured to establish the route by;

    mapping at least one adjacent ad hoc cluster to the corresponding gateway terminal and the corresponding master terminal; and

    communicating with the corresponding master terminal associated with the selected one of the plurality of routes via the corresponding gateway terminal to support intra-cluster scheduling and forwarding of the communication packet from the second terminal.
