LINK SIGNAL-TO-NOISE AWARE ROUTING OVER MOBILE AD HOC NETWORKS (MANETS)

摘要

The present invention provides a method and apparatus for routing a data flow from a source node to a destination node in a mobile ad-hoc network (MANET). The present invention performs this function by first determining a quantitative value for each link at an individual node in the MANET, where the value represents the current quality level of each of the links. Next, the present invention broadcasts an advertisement for each of the links in the MANET by each of the nodes, the advertisement including the value determined above. After broadcasting the advertisement, routing tables are composed at each of the nodes based upon the advertisements. Each routing table includes the value determined above. After composing the routing tables, a route based upon the routing table (and the link values contained therein) is selecting by the source node to direct the data flow to the destination node.
