Apparatus and method for collecting active route topology information in a mobile ad hoc network
First Claim
1. For use in a mobile ad hoc network formed by a plurality of mobile ad hoc network (MANET) nodes, a first MANET node capable of collecting route information associated with a first route from a source MANET node to a destination MANET node, said first MANET node comprising:
- a radio frequency (RF) transceiver capable of wirelessly communicating with other ones of said plurality of MANET nodes according to an ad hoc on-demand vector (AODV) protocol; and
a controller capable of receiving incoming data packets from said RF transceiver and sending outgoing data packets to said RF transceiver, wherein said controller receives a Path Marker Request message generated by said source MANET node and retrieves first route topology data associated with said first route from said first Path Marker Request message, said first route topology data identifying all intermediate MANET nodes in said first route coupling said first MANET node to said source MANET node.

Abstract
A first MANET node that collects route information associated with a first route from a source MANET node to a destination MANET node in a mobile ad hoc network (MANET). The first MANET node comprises: 1) a radio frequency (RF) transceiver for wirelessly communicating with other MANET nodes according to an ad hoc on-demand vector (AODV) protocol; and 2) a controller for receiving incoming data packets from the RF transceiver and sending outgoing data packets to the RF transceiver. The controller receives a Path Marker Request message generated by the source MANET node and retrieves first route topology data associated with the first route from the first Path Marker Request message. The route first topology data identifies all intermediate MANET nodes in the first route coupling the first MANET node to the source MANET node.

11. For use in a mobile ad hoc network formed by a plurality of mobile ad hoc network (MANET) nodes, a method of collecting route information in a first MANET node, the route information associated with a first route from a source MANET node to a destination MANET node, the method comprising the steps of:
-
receiving in the first MANET node a Path Marker Request message generated by the source MANET node; and retrieving first route topology data associated with the first route from the first Path Marker Request message, the first route topology data identifying all intermediate MANET nodes in the first route coupling the first MANET node to the source MANET node. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
