Soroush, We have had limited success running experiments using EC2. At one time we did a comparative analysis of a single experiment using EC2 vs. a physical testbed. The number of nodes was held constant and at fixed intervals the traffic load was increased. At some point, there was some interaction that led to the 802.11 EC2 emulation falling apart. This may have been caused by EC2 imposed CPU and/or I/O limitations affecting the collision estimators in the model.
It is hard to speculate as to why your emulation has an upper limit of 39 nodes. Have you examined emulator statistics, specifically the drop tables, to determine why you are losing traffic? -- Steven Galgano Adjacent Link LLC www.adjacentlink.com On 11/02/2015 03:18 PM, [REDACTED] wrote: > Hello, > > Here is my server resources that I've used . > I've used amazon EC2 . > m4.2xlarge server which has : vCPU ECU Memory > 8 26 > 16 > here is my platform configuration for each instance or node: > for instance :(This is node 5 ) > > <?xml version="1.0" encoding="UTF-8"?> > <!DOCTYPE platform SYSTEM "file:///usr/share/emane/dtd/platform.dtd"> > <platform> > <param name="otamanagerchannelenable" value="on"/> > <param name="otamanagerdevice" value="eth1"/> > <param name="otamanagergroup" value="224.1.2.8:45702 > <http://224.1.2.8:45702>"/> > <param name="eventservicegroup" value="224.1.2.8:45703 > <http://224.1.2.8:45703>"/> > <param name="eventservicedevice" value="eth1"/> > <param name="controlportendpoint" value="0.0.0.0:47000 > <http://0.0.0.0:47000>"/> > > <nem id="5" definition="rfpipenem.xml"> > <transport definition="transvirtual.xml"> > <param name="address" value="10.100.0.5"/> > <param name="mask" value="255.255.255.0"/> > <param name="bitrate" value="1000000"/> > <param name="broadcastmodeenable" value="yes"/> > </transport> > </nem> > </platform> > > also using eventservice, eelgenerator and Scenario.eel files. > > This configuration work up to the 39 nodes but more than that I am > losing connection between nodes. > actually, I am able to ssh to nodes but not able to ping node's radio > from each other. > Do you have any idea about my issue? > > Thanks, > Soroush _______________________________________________ emane-users mailing list [email protected] http://pf.itd.nrl.navy.mil/mailman/listinfo/emane-users
