Hi, I need some help to understand AODV routing protocol specification. when we have just a source of data and a destination in range of transmission, and hello messages are activated. Normally, the source will check the routing table and will find the destination (because they already exchange hello messages), so RREQ will not be needed. Am I right or I miss understand it, because when I simulate such scenario, I found a RREQ initiated in spite of hello message are already sent. I am not of the necessity of hello here? some clarification will be welcome thkx best regards Fatma
