Hierarchical mobile ad-hoc network and methods for performing reactive routing therein using ad-hoc on-demand distance vector routing (AODV)
First Claim
1. A method for sending data in a wireless ad-hoc network comprising a plurality of nodes grouped into clusters of nodes and a plurality of wireless links connecting the plurality of nodes, each cluster having a designated cluster leader node, the method comprising:
- sending a cluster-level route request from a source node of a source cluster to a cluster leader node of the source cluster;
determining a cluster-level route between the source cluster and a destination cluster comprising a destination node responsive to the cluster-level route request and using a plurality of the cluster leader nodes;
determining a node-level route from the source node to the destination node along the cluster-level route, each node along the node-level route storing an address of a next node along the node-level route; and
transferring data from the source node to the destination node via the node-level route based upon the addresses of each next node along the node-level route.

Abstract
A method is provided for sending data in a wireless ad-hoc network including a plurality of nodes grouped into clusters of nodes and a plurality of wireless links connecting the plurality of nodes, where each cluster has a designated cluster leader node. The method may include sending a cluster-level route request from a source node of a source cluster to a cluster leader node of the source cluster, and determining a cluster-level route between the source cluster and a destination cluster including a destination node responsive to the cluster-level route request and using a plurality of the cluster leader nodes. Further, a node-level route may be determined from the source node to the destination node along the cluster-level route, and each node along the node-level route may store an address of a next node along the node-level route. Additionally, the data may be transferred via the node-level route based upon the stored addresses.

25. A mobile ad-hoc network comprising:
-
a plurality of nodes grouped into clusters of nodes, each cluster having a designated cluster leader node; and
a plurality of wireless links connecting said plurality of nodes;
said plurality of nodes sending data therebetween by sending a cluster-level route request from a source node of a source cluster to a cluster leader node of said source cluster, determining a cluster-level route between said source cluster and a destination cluster comprising a destination node responsive to the cluster-level route request and using a plurality of said cluster leader nodes, determining a node-level route from said source node to said destination node along the cluster-level route, each node along the node-level route storing an address of a next node along the node-level route, and transferring data from said source node to said destination node via the node-level route based upon the addresses of each next node along the node-level route. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
