NL_R_AODVRouteRequest performs the AODV Route Request process from the source node S towards the destination node D inside the network graph G (WEB). The sequence number I is assigned to the process in order to distinguish between old and fresh routes. The research is limited by the maximal quantity of nodes T that a discovery packet can cross before its rejection by the network. The set of RREQs (respectivelly possible routes) is stored into the matrix M (respectivelly R) with the format [route|arrival|TTL|route length].
