1. A method for restricting network access between nodes in an ad-hoc communications network, said nodes being adapted to transmit and receive signals to and from other nodes in said ad-hoc network, the method comprising:

  • controlling a first node in said ad-hoc communications network to receive a request for network access from a second node and in response, controlling at least one node in said network to calculate a location of said second node;

    controlling said first node to allow said second node to have access to said network if said location of said second node is within a network access restriction boundary;

    controlling said first node to communicate said request for network access to a third node; and

    controlling said third node to communicate to said first node a request for said location calculation of said second node and in response, controlling said first node to calculate said location of said second node and communicate said location to said third node.
