loadbalncing in olsr

[Manojkumar Annamraju]

hi alfonso,

           i am  doing loadbalancing in olsr protocol.i need to change the route which node is highest enegry.my doubt is if i can change the olsr routing protocol ,how to recompile the modified olsr protocol.


         please alfonso help me...................

    

[Alfonso Ariza Quintana]

Build, if you select build the new code will be recompiled

ok alfonso thank u

hi alfonso,

    in inetsimplebattery .cc file contains registerwirelessdevice() method is there,  my doubt is  i use the inetsimplebattery module in my adhoc host,but my doubt is how to register the this adhoc host device. so please expalin .................

[Alfonso Ariza Quintana]

see
void Radio::registerBattery()

is this method that register the radio interface in the battery model

hi alfonso,

       i add the inetsimplebattery module in adhoc host module i added,but how can i know this this adhochost is registerd .

[Manojkumar Annamraju]

hi alfonso,

         in AnalysisEnergy module ,void AnalysisEnergy::SnapshotEnergies()  in this method the energy values of host is stored in the filename(// "energies-$network-$run-$time.snapshot
    std::stringstream filename;
    filename << "energies-" << simulation.getSystemModule()->getName() << "-"
    << "-" << simTime() << ".snapshot";)

actuallly i used this module in my adhost module,and also i given the parameter values. but  i am not accesing the above file.

pls tell me how to access that file  in tcl/tk environment.

[Alfonso Ariza Quintana]

You can't access this file from the tcl/tk

The battery module shows in the IDE the residual energy. Open the battery module and search the parameter
lastPublishCapacity

[Manojkumar Annamraju]

alfonso i am using AnalysisEnergy module in my adhochost,i am using olsr protocol and while running the my network ,how can i findout the energy of the host.

Open the Battery module and search the parameter lastPublishCapacity

[Manojkumar Annamraju]

hi alfonso, i am not getting the battery module please help  me how to enter into the batterymodule at runtime

[Alfonso Ariza Quintana]

The battery module must be included in the node definition, you can't included the battery model in run time

sir can you tell me how to include batterymodule at runtime .pls tell me .....

[Manojkumar Annamraju]

hi sir, i included the battery module ,and in inspect objects i am not finding the lastmodulecapacity parameter .pls help me how to find the  host power while running.pls help me................

[Alfonso Ariza Quintana]

the parameters exist in InetSimpleBattery I have just checked, but the radio module must inform to the battery module the consume in every state (idle, transmission, reception ...)

---

Date: Mon, 2 Apr 2012 19:32:25 +0530

[Manojkumar Annamraju]

yes i get the lastpublishcapcity,the value is fixed it is not consuming the energy.how to reduce the energy value while forwarding the packet of the node

[Alfonso Ariza Quintana]

the radio module must register the consume in every state, if the radio module doesn't register the consume the  charge will continue constant .


See the 802.15.4 radio module code

[Manojkumar Annamraju]

hi alfonso,

   

    i checked the 802.15.4 radio module code,but i didn't understand ,how the how the radio module is registered in battery module.I also checked the analysis energy module but i didn't get.please can u tell me how to register the radio module in inetsimplebattery module .pls 

explain.................

[Manojkumar Annamraju]

i checked the 802.15.4 radio model, but i didn't get .please tell me how to register the radio module in battery module .

[Behrouz Seyedi]

I have this problem too...
look at this post:  residual capacity isn't changing

[Alfonso Ariza Quintana]

void Ieee802154Phy::registerBattery()

[Behrouz Seyedi]

you must add this parameters in omnetpp.ini

for example:

**.usage_radio_idle = 2mA
**.usage_radio_recv = 3mA
**.usage_radio_send = 4mA
**.usage_radio_sleep = 1mA
for more information see: Radio.ned

[Manojkumar Annamraju]

hi Behrouz Seyedi ,

after adding these parameters theenergy is reducedor not

[Behrouz Seyedi]

I added this parameters in omnetpp.ini and it works. my simulation time is 100 seconds.

**.battery.nominal = 950
**.battery.capacity = 950
**.battery.voltage = 3.6
**.battery.resolution = 1s
**.battery.publishDelta = 0.05
**.battery.publishTime = 1s
**.battery.ConsumedVector = true

**.usage_radio_idle = 216mA
**.usage_radio_recv = 260mA
**.usage_radio_send = 375mA
**.usage_radio_sleep = 9mA

I have tested the battery in inetmanet-2.0 and it run, it's necessary to include in the ini file
**.batteryType = "InetSimpleBattery"
**.usage_radio_idle = 1mA
**.usage_radio_recv = 2mA
**.usage_radio_sleep = 0mA
**.usage_radio_send = 2mA
or the values of consume that you want

I can't reproduce your problem, I have run the example net80211_aodv with a battery module and with a consume in the radio module and I have obtained this graphics for the consume battery.

Hi Alfonso, I tried adding the lines you recommended, but I'm having some problems:

When I try to put the line:

**. BatteryType = "InetSimpleBattery"

a warning is generated

Unused entry (does not match any parameters)

I'm using Omnet 4.2.2 with the newest version of INET 2.0.0, running the example net80211_aodv.

The only result achieved on energy are:

For the simulation time of 300s

in both results have the same "residual capacity"

It was also not recorded any consumption information in the files of vector and scalar

Someone already got some runs in this new example versção INET 2.0.0 that has correctly calculated the energy consumption?

Hi, could you please tell me how to access the residual battery of the node processing msg in rreq_process (in net80211_aodv)?

thanks

[Sh Asaadi]

Hi dear Alfonso. I have 2 questions important to me, could you please answer me.

1) Could you please tell me how to access the residual battery of the node, processing msg, in rreq_process (the code statement in net80211_aodv)? 

2) How to find neighbors that are in the transmission range of a node? I want to add this neighbors in a table and associate a trust value to each neighbor. how to find the neighbors?

Many Thanks

[Alfonso Ariza Quintana]

 

BasicBattery *bt = BatteryAccess().get();

bt->GetEnergy()

The neighbors nodes list is a bit more complex, you need to run the hello protocol and extract from the routing table nodes that the distance is 1 hop

Thank you Alfonso.

If possible please tell a little about how to use hello protocol? or if there is an example in inet framework using hello protocol let me know please.

Thank u.

Dear Alfonso,

i have added **.llfeedback=false

and **.optimized_hellos=false.

Now how to use hello protocol to determine 1 hop neighbrs? could you please explain a little? and where to change the code?

Thanks

[Alfonso Ariza Quintana]

The hello protocol will include all the nodes to 1 hop in the routing table

[Shima Asaadi]

Thanku Alfonso, I got it.

Do you know how to find one hop and two hop neighbors of a node?

[Alfonso Ariza Quintana]

I recommend to study the hello protocol of OLSR protocol, this hello allows to discover 2 hops nodes, the idea is to include the list of nodes that the node has listened a hello message in his hello messages, with this it is possible to discover 1 and 2 hops nodes

How should i use OLSR protocol for finding neighbors in omnet++ 4.6?

[Alfonso Ariza Quintana]

Inetmanet has included the OLSR protocol

[mento...@gmail.com]

Will you please write down the code for finding the one hop and two hop neighbors?
and suggest me a good book or tutorial for learning omnet++ for node scheduling in adhoc networks. It will be a huge favor.

Thank you Alfonso. It works I am able to find one hop and two hop neighbors.
I have to work at TDMA base MAC layer for node scheduling. Does OLSR work with TDMA?

[Alfonso Ariza Quintana]

OLSR is a network layer protocol, it is independent of the link layer technology
