<p><P>PROBLEM TO BE SOLVED: To provide a method for discovering disjoint routes from a mobile node to multiple service nodes which may provide a service to the mobile node in an ad-hoc network including a plurality of nodes. <P>SOLUTION: The present invention relates to a method comprising the steps of: sending a route request from a mobile node; distributing the route request by nodes of a network; if a route request reaches a service node, sending back a route reply comprising the trace of the route request from the mobile node to the service node; determining disjoint routes based on the route replies received by the mobile node; and, if the route replies received by the mobile node are not corresponding to the disjoint routes of a sufficient number, issuing a new route request comprising an increment path expansion parameter. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
