Abstract:
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 forming the tube of multiple communication paths to obtain one of unidirectional and bidirectional communications; 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.
