System and method for determining relative positioning in ad-hoc networks
First Claim
1. A method for displaying node location information in an ad-hoc communications network, said network including a plurality of nodes being adapted to transmit and receive signals to and from other nodes in said network, the method comprising:
- distributing a plurality of nodes at a deployment area and calculating a position of at least one node of said plurality based on at least one distance measurement calculated by said plurality, and controlling said plurality to communicate said position to a first node of said plurality; and
controlling said first node of said plurality to calculate and to display at least one of an absolute position of said at least one node, a relative position of said at least one node and a first path of said at least one node.

Abstract
A system and method for improving the ability of a portable voice and data wireless communications network to provide position information regarding mobile nodes located within a network. The system and method employs mobile access points, wireless routers, and mobile nodes, which each contain at least one transceiver, and are mounted or dispersed at a geographic location. Access points can be connected to mobile vehicles, or connected to a network management system, and wireless routers can be mounted to portable stands for easy deployment. Mobile nodes can be attached to equipment or personnel for tracking purposes, and each 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.

13. A system for displaying node location information in an ad-hoc communications network, said network including a plurality of nodes being adapted to transmit and receive signals to and from other nodes in said network, the system comprising:
-
a plurality of nodes, adapted to deploy and to occupy a deployment area and in response, to calculate a position of at least one node of said plurality based on at least one distance measurement calculated by said plurality, and to communicate said position to a first node of said plurality; and
said first node, adapted to calculate and to display at least one of an absolute position of said at least one node, a relative position of said at least one node and a first path of said at least one node. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
