System and method for determining physical location of a node in a wireless network during an authentication check of the node
First Claim
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.

Abstract
A system and method for providing security to a wireless network by using a mobile node'"'"'s location as a parameter for deciding if access is to be given to the node. The system and method employ access points, wireless routers and mobile nodes, each including at least one transceiver adapted to transmit and receive communication signals to and from other wireless routers, mobile nodes and other mobile access points. Each access point is connected to a network management system which allows enhanced network monitoring and control. Each network node includes technology which may determine an absolute node location containing latitude, longitude and altitude of a node, or a relative node location containing the distance and angle between nodes, or a combination of both absolute and relative location data.
