[B.A.T.M.A.N.] Error " LibG3D-WARNING **: no handler for file " with meshs3d
by thomas anderson 15 Jun '08

When i start meshs3d i can see the ip of the access point but not the image and on shell i got this errors: (process:29085): LibG3D-WARNING **: no handler for file 'objs/accesspoint.3ds' found (process:29085): LibG3D-WARNING **: no handler for file './objs/accesspoint.3ds' found (process:29085): LibG3D-WARNING **: no handler for file '../objs/accesspoint.3ds' found (process:29085): LibG3D-WARNING **: no handler for file '../../objs/accesspoint.3ds' found (process:29085): LibG3D-WARNING **: no handler for file 'objs/accesspoint_inet.3ds' found (process:29085): LibG3D-WARNING **: no handler for file './objs/accesspoint_inet.3ds' found (process:29085): LibG3D-WARNING **: no handler for file '../objs/accesspoint_inet.3ds' found (process:29085): LibG3D-WARNING **: no handler for file '../../objs/accesspoint_inet.3ds' found (process:29085): LibG3D-WARNING **: no handler for file 'objs/internet.3ds' found (process:29085): LibG3D-WARNING **: no handler for file './objs/internet.3ds' found (process:29085): LibG3D-WARNING **: no handler for file '../objs/internet.3ds' found (process:29085): LibG3D-WARNING **: no handler for file '../../objs/internet.3ds' found (process:29085): LibG3D-WARNING **: no handler for file 'objs/btn_close.3ds' found (process:29085): LibG3D-WARNING **: no handler for file './objs/btn_close.3ds' found (process:29085): LibG3D-WARNING **: no handler for file '../objs/btn_close.3ds' found (process:29085): LibG3D-WARNING **: no handler for file '../../objs/btn_close.3ds' found (process:29085): LibG3D-WARNING **: no handler for file 'objs/s3d_berlios_de.3ds' found (process:29085): LibG3D-WARNING **: no handler for file './objs/s3d_berlios_de.3ds' found (process:29085): LibG3D-WARNING **: no handler for file '../objs/s3d_berlios_de.3ds' found (process:29085): LibG3D-WARNING **: no handler for file '../../objs/s3d_berlios_de.3ds' found The file are present in that folder but seem that meshs3d can't find it right?

Hi guys! I'm trying to compile B.A.T.M.A.N. for the fonera 2100 from svn http://downloads.open-mesh.net/svn/batman/trunk/batman/ (is in this directory the latest svn code for B.A.T.M.A.N. ?), but i don't know how cross compile for fonera 2100 ... Can you help me? Eidos

[B.A.T.M.A.N.] Theoretical Research w.t.r B.A.T.M.A.N.
by Daniel Heldt 13 Jun '08

13 Jun '08

Hi there, Exists there any theoretical work about batman's routing properties? For example a model explaining batman as some kind of 'ant-routing' or statements a'la "If the network and load balance does not change for a long enough time, than the routing tables converge agains a nash-equilibrium." Do you know, if anybody is working in that direction, or is 'out there' somebody interested in this kind of work? with kind regards, daniel

[B.A.T.M.A.N.] Multiple radios to improve throughput
by Shane Chao 12 Jun '08

12 Jun '08

Elektra, Thank you for pointing out in May 08 that most embedded boards do not have enough CPU power to saturate the capacity of single radio link. I was experimenting Batman in a straight line, three node configuration with the middle node having two radios so it doesn't have to switch between node 1 and node 3. My configuration is as follows: node 1 node 2 node 3 ------ ------ ------ ath0 <--ch 1--> ath0 ath1 <--ch 11-> ath0 When I ran iperf between node 1 and 3, I did not see any throughput improvements with either one or two radios in node 2. I even stopped Batman and manually setup the routes and the performance remains the same. However, when I upgrade node 2 from a 200MHz CPU board to a 500MHz CPU board, the bandwidth went up 50%. So thanks again for pointing out my bottleneck:) Lastly, can someone suggest some embedded boards fast enough to push wifi radios to its limits? Thanks, Shane

[B.A.T.M.A.N.] 0.3 final <-> quagga
by Antony Chazapis 11 Jun '08

11 Jun '08

Hi all. I have made a new version of the patch posted by acinonyx (rv502), for interfacing batmand with the zebra routing daemon. There are 2 versions available: One for the latest svn (rv1060) and one for the stable 0.3 release. Take a look at: http://www.cslab.ece.ntua.gr/~chazapis/batman/ Please consider this code experimental. Some initial tests are promising, but there may be bugs... :) For now, the plug-in just supports sending routes to zebra, not the opposite (redistributing routes from other protocols). That was also the case with the older - rv502 - version. What the patch does is: - Adds a flag "-z" to the batmand executable which may be used to enable zebra communication and accepts as an argument the path to the corresponding zebra unix-domain socket. - If zebra is enabled: - No rules are added to the kernel. - All UNICAST routes are sent to zebra. All routes are also sent to the kernel (in linux/route.c), but the extra routing tables are not used by linux, because of the lack of rules. These routing tables remain, just to help with route management, so batmand can successfully remove all added routes on shutdown. Antony

[B.A.T.M.A.N.] Batman & multiple radios
by Damian Ivereigh 10 Jun '08

10 Jun '08

I am seriously looking at using B.A.T.M.A.N. to drive a mesh network in a small town in Australia. One of the hassles with typical mesh networks is the way the performance drops off when you have many hops, due to the radio having to keep switching between send and receive. The standard way to get around this appears to be to use multiple radios. How is this done with batman? Is it a case of having multiple directional aerials - such that one radio can be receiving from one direction and another can be sending to the next node up the chain? It makes sense to put the local traffic (e.g. running a local AP) on a separate radio from the "back haul". Does anyone have any experience with sort of layout? The main driver here is performance rather than coverage. Damian -- Launtel - Plugging Tassie into the world Tel: 1800LAUNTEL (1800528683) Mob: 0418217582 Fax: 1300784109 http://www.launtel.net.au

[B.A.T.M.A.N.] Batman-Advanced Kernel land
by cipollone 10 Jun '08

10 Jun '08

Hi, I'm testing Batman-Advanced on Open WRT. I've compiled the package release # 1074 (the last from svn) and I'm working on a X86 machine. I've installed Batman Advanced on 2 virtual machine (using Qemu and Vde Switch, software used to create the simulation environment) and, after the configuration of the interface and the assignation of the IP address on each bat0 device I've tried to test the connection between the machine using ping command. Well, the ping crash the reciver machine. I only have to restart becouse it doesn't answer. Someone can help me? Regards, Paolo
