  • Routing protocol for ad hoc networks
    Patent number: 7719989
    Abstract: A routing method for an ad hoc network is disclosed, the network comprising two or more nodes (A, B, C, D, E, F), and the method comprising: sending a message from a start node (A) to a finish node (F) via one or more intermediate nodes (B, C, D, E); each of the start node (A) and intermediate nodes (B, C, D, E) receiving an acknowledgement signal (AckB, AckC, AckD, AckE, AckF) from a one-hop neighboring node when the one-hop neighboring node receives the message from the start node (A;F) or intermediate nodes (B, C, D, E) and, in the case of the one-hop neighboring node not being the finish node (F), the start node and intermediate nodes receiving an acknowledgement signal (AckC, AckD, AckE, AckF) from a two-hop neighboring node when the two-hop neighboring node receives the message from the one-hop neighboring node.
