Engineering Clinic

Dear readers,  Thanks are using my website for technical information. Scaling to a new level, I have published two apps in Windows 8 app store, one related to linux kernel and other on Embedded systems Of course, both of the mateirals are already there in this blog.  So readers can download offline to see the contents related to embedded system and linux kernel and the advanatage is, they are free to download. Here are the links to download Embedded Systems -  http://apps.microsoft.com/webpdp/app/embeddedsystems/d38a2fd9-1ca3-4e17-a003-ef3be532608b Linux Kernel App - http://apps.microsoft.com/webpdp/app/linux-kernel/a61626c3-f135-4492-8a3d-64bd84c7ab40 I am planning to launch these and other apps in android also soon. Wait for my apps.

Enabling or using energy for a wireless node is always giving the accurate results. Be default, when node-config is done is NS2, the energy supplied is infinite, means there is no energy log is been carried out. you can see the following code below: #Node configuration without energy Model $ns node-config -addressType hierarchical \ -adhocRouting AODV \ -llType LL \ -macType Mac/802_11 \ -ifqType Queue/DropTail/PriQueue \ -ifqLen 50 \ -antType Antenna/OmniAntenna \ -propType Propagation/TwoRayGround \ -phyType Phy/WirelessPhy \ -topologyInstance \$topo \ -channel Channel/WirelessChannel \ -agentTrace ON \ -routerTrace ON \ -macTrace OFF \ -movementTrace OFF #here is the change in which you can enable the energyMode...

A Visual trace analyzer is been developed by Mr. Fernando and you can download freely from his website http://nsvisualtraceanalyzer. wordpress.com/ This software is been developed using .NET C# 4.0 This software will run only in windows and not tested in Wine platform of Linux (May be will work) in future, the same software will be processed using Java as most of the OS will run. download from this url : http://student.dei.uc.pt/~ frocha/ns/NS2- VisualTraceAnalyzer-0.2.72.zip   here is the manual: http://nsvisualtraceanalyzer. files.wordpress.com/2012/07/ ns2-visual-trace-analyzer- manual.pdf This software accepts a tcl, trace files, scenario files and interprets the contents and displays results like throughput,data, etc. Also there is a provision for graphing too.. Its a very great handy tool for NS2 (particularly beginners to researchers).. Here are some of the screen shots of the software Open a Tcl File and shows the second picture as shown in the next pi...

The node configuration in ns2 is a special task in which the number of nodes can be configured for a set of parameters. The following table tells about the node  configuration parameters as defined in the ns-lib.tcl The readers are requested to refer the ns-lib.tcl file for more information.
