Linux Kernel and Embedded Systems Apps in Windows 8

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.

Energy Model in Network Simulator 2 (NS2)

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 energyModel for Wireless networks

$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 \
                   -energyModel "EnergyModel" \
                   -initialEnergy 3.4 \
                   -txPower 0.33 \
                   -rxPower 0.1 \
                   -idlePower 0.05 \
                   -sleepPower 0.03 \
                   -channel Channel/WirelessChannel \
                   -agentTrace ON \
                   -routerTrace ON \
                   -macTrace OFF \
                   -movementTrace OFF


in the above code, the red colored code indicates the enabling of energy Model for a given network.
Here, the initial Energy is given in Joules (but you need not specify the unit)
and the txPower, rxPower, sleepPower and idlePower are given the units in Watts (here also no unit need to be specified)
As you aware of the formula: Energy = Power * time
