Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for selecting a path for transmitting a data packet between nodes in an ad hoc network. SOLUTION: The method includes determining a metric which is indicative of link stability between the nodes in the network, initiating a route discovery procedure that generates a plurality of candidate transmission paths between a source node and a destination node (S24), and selecting a transmission path among the plurality of candidate paths using the metric for nodes associated with each candidate path (S25). The metric is further defined as link duration (i.e., an amount of time the node maintains a link with neighboring nodes). COPYRIGHT: (C)2007,JPO&INPIT
