[ns] mobiltiy model with obstacle and voroni graphs
has any one simulated obstacle mobility model in ns-2 and created pathways using the voronoi diagrams. i am working on mobility modelling and anomaly detection using mobility models. any help is welcome -- B Sriram India mob : 09733706981

hi i am simulating a basic wireless networknbsp; using the program wireless1.tcl given in tutorials. (a) is there any way that i can create the set val(cp) file automatically (b) how do i generate random source node and destination node pairs in the network i.e any node can be at random be a source and send packets to any other node. -- B Sriram

Assuming that i have the following mobility scenario where i am interested for Node 49: $node_(49) set X_ 696220.00 $node_(49) set Y_ 260720.00 $node_(49) set Z_ 0.0 $ns_ at 7.0 $node_(49) setdest 696193.8102 261479.3690 8.1233 .. .. /* Other Node movements */ .. .. $ns_ at 41.0 $node_(49) setdest 696269.3069 261551.7842 8.7203 While reading the Nam trace file i can see that at Time= 27.0 , node 49 is at the following coordinates ( 696087.18 , 261285.68 ). These coordinates are no where included in the mobility scenario. How did ns-2 obtain these coordinates? Do you know how ns-2 implements node movements? Is there an algorithm for this? Thanks in advance. -- _ Nicholas Loulloudes High Performance Computing Systems Laboratory (HPCL) University of Cyprus, Nicosia, Cyprus Tel: +357-22892663 Email: loulloudes.n[at]cs.ucy.ac.cy does the setdest file not have any mention of node activity during that time. i am trying to implement a wireless n/w and generate the scen file using setdest and save it in the scen folder. i shall run my simulations and see if anything like that turns up. -- B Sriram
[ns] reply : bi-directional traffic simulation (???)
i too experienced segmentation faults for a similar nature of work however when i increased the time difference between the two traffic it was not there. try and tell me if it works -- B Sriram
