Hi All, I am trying to emulate a simple network of two nodes - a ground node, and another mobile node which, from an elevation, moves up from the ground node at around 45 degrees for a certain duration, makes a circle with a specific radius at that point, and comes back to the same point where it started. The idea is to set up opportunistic contact between the two nodes. For the purpose of simplicity, I have made a IEEE802.11bg wifi connectivity between the two nodes, with the default values given by CORE (txpower of 0 dbm and frequency of 2.347 GHz). I use EMANE events to trigger the above mobility. For the mobility model, I have used MNM tools to generate an EEL file which contains GPS location and pathloss events per second for a duration of 10000 seconds.
The problem is the following: While the location events are duly recognized by CORE, I suspect that the pathloss events are not being recognized properly. Going by a previous post on the EMANE users group, I have attached the output of the following emane shell commands: 1) emanesh localhost get stat '*' all (stats.txt) 2) emanesh localhost get table '*' all (tables.txt); 3) emanesh localhost get config '*' all (config.txt). >From the table output, I see no indication of pathloss events received in the mobile node, against the ForwardPathLoss and the ReversePathLoss tables (while emaneeventservice executed with debug level info reports sending pathloss message). Also, a visual indicator (I presume) for pathloss at some point in the motion should be packet loss. I have empirically determined that connectivity between nodes for the above values should stop roughly around 1500-2000 metres between them (assuming all default values for IEE802.11bg for EMANE in CORE network emulator). I observe that even beyond this point, there is no packetloss (as pathloss should have caused), and neither does visual adjacency in CORE disappear/turn grey. Appreciate any assistance that I may get from the forum. Thanks, Vijay
