Hi All, I am using NS-2.28 and default AODV implementation on it. During some simulations, when number of nodes are high, there are a lot of dropped packets and repeated RREQ packets.
The reason logged indicates that the link layer reports that a route failed. Although, routes are again found, this seriously hampers the throughput. I am not sure that this is "correct" simulation. My scenario has static nodes (no mobility and no change in topology during the simulation), no error model and a simple two-ray ground propogation model. Why should link layer conditions change at all in such a scenario and why should there be drops due to that ? It would be really great if somebody could provide some insight. Thanks and Regards, Kanthi
