Abstract: A wireless ad hoc network comprising a plurality of nodes, each of the nodes has a dynamically determined role, a portion of the nodes are designated with the role of super node and the remaining of the nodes are designated with the role of ordinary nodes, the super nodes form the routing backbone of the network, each of the nodes includes a transmitter, transmitting messages over a wireless medium, a receiver, receiving messages over a wireless medium, a local topology processor, coupled with the transmitter and with the receiver, maintains a local topology database, the local topology processor further determines the role of the node, a network topology processor, operative when the role of the node is super node, coupled with the transmitter, with the receiver and with the local topology processor, maintains the network topology database, and establishes and terminates a dedicated backbone routing link with each one hop super node neighbor, a routing processor, coupled with the transmitter, with the receiver, with the local topology processor and with the network topology database, maintains a local routing table according to the local topology database, and constructs a network routing table, according to the network topology database, when the node is a super node, wherein, each of the nodes attempts to communicate with at least a minimal number of one hop super-node neighbors.
