MOBILE AD-HOC NETWORK (MANET) AND METHOD FOR IMPLEMENTING MULTIPLE PATHS FOR FAULT TOLERANCE
First Claim
1. A method for communicating between a source node and a destination node in a mobile ad-hoc network (MANET) also comprising a plurality of intermediate nodes, the method comprising:
- providing a plurality of mobile wireless communications devices, each comprising a wireless transceiver and forming the MANET as source, destination, intermediate and standby nodes;
establishing a main communication path between the source node through intermediate nodes to the destination node based on an underlying routing protocol;
establishing alternative communication paths among neighboring nodes as standby nodes that are positioned an “
n”
hop distance from nodes of the main communication path to form a tube of multiple communication paths from the source node to the destination node; and
reconfiguring the main communication path within the tube of multiple communication paths to an alternative communication path using at least one standby node when the main communication path is broken.

Abstract
A mobile ad-hoc network (MANET) communicates between a source node and destination node and includes a plurality of intermediate nodes. A main communication path is established between the source node through intermediate nodes to the destination node based on an underlying routing protocol. Alternative communication paths are established among neighboring nodes as standby nodes that are positioned an “n” hop distance from nodes of the main communication paths to form a tube of multiple communication paths from the source node to the destination node. The main communication path reconfigured within the tube of multiple communication paths to an alternative communication path using at least one standby node when the main communication path is broken.

11. A method for communicating between a source node and a destination node in a mobile ad-hoc network (MANET) also comprising a plurality of intermediate nodes, the method comprising:
-
providing a plurality of mobile wireless communications devices, each comprising a wireless transceiver and forming the MANET as source, destination, intermediate and standby nodes; establishing a main communication path between the source node through intermediate nodes to the destination node based on an underlying routing protocol; establishing alternative communication paths among neighboring nodes as standby nodes that are positioned an “
n”
hop distance from an adjacent node within and forming part of the main communication path to form a tube of multiple communication paths from the source node to the destination node, wherein each standby node monitors a selected neighboring standby nodes and nodes in the main communication path to determine if data packets are being forwarded and transmitted successfully; andreconfiguring the main communication path within the tube of multiple communication paths to one of said alternative communication paths using at least one standby node when the main communication path is broken. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

a source node, a destination node and a plurality of intermediate nodes forming a main communication path based on an underlying routing protocol; a plurality of neighboring nodes as standby nodes that are positioned an “
n”
hop distance from nodes of the main communication path to form a tube of multiple communication paths as alternative communication paths from the source node to the destination node, wherein each standby node is operative for monitoring selected other neighboring standby nodes and nodes within the main communication path to determine if data packets are being forwarded and transmitted successfully and reconfiguring the main communication path within the tube of multiple communication paths using at least one standby node when the main communication path is broken. - View Dependent Claims (22, 23, 24, 25, 26, 27)
