Clustering Nodes In Ns2

Hy,
I am new to linuxquestion.org, however i am mid-level linux administrator.

As per my scenario, I want to cluster python and java services in two nodes running RHEL 6.4. Till now by watching tutorial I have seen application level clustering of linux for eg: webserver, mysql database and so on. However I haven't found any with python & java clustering.
I am already familiar with windows clustering having clustered ip of the two nodes. In my scenario, we have both the options open either going with active-active or active-passive cluster. So I want to some sort of idea to achieve linux os clustering and hence obtained clustered ip.
Further any idea on how this service will float from one node to another. Further, I cannot get to the fencing mechanism in Linux. Any idea for this will be helpful to understand.

Hope to get positive respond ASAP. Thanks in advance for those who help me with this.

how can i add k-means algorithm on zrp protocol ?????? in ns2?
I want to add k-means clustering alg. for ZRP protocol to make it run with the inter-zone routing protocol for inter clustering and with intra-zone for intra clustering. note that i am using ns-2.35/ubuntu10.04 and the ZRP was completely added to the simulator

hello

I want to setup two desktops each one having 4 cores and combine them to have 8 cores with linux clustering. Is this how clustering works and what level of difficulty is it?

Also, any good howto sites on the subject is appreciated. Thanks

Hi everyone,

I have final year project related to the LEACH routing protocol. I want to change the number of nodes for LEACH? As for existing package, it is already 100 nodes, and i want to change it to 80 nodes and below..what should I do?

Thanks

Hi,

I intend to use mannasim script generator tool to create mobile nodes for routing protocols like aodv, leach , dsdv and dsr.

To be best of my knowledge, WSN nodes in mannasim are assumed to be static but I would like to know if there is a resource available which explains how the tcl code can be modified to achieve node mobility.

I have tried searching google but I haven't gotten satisfying search result.

It seems is better to ask an experienced ns2/mannasim user.

Be sure your kind response is valued

i am trying to simulate Tora for 50, 110, 170 and 200 number of nodes. but for 50 number of nodes trace file become so large that it does give segmentation fault error when i tried to extract results with awk file. for 100 number of nodes simulation never comes an end. please help me... if m missing something ...

hello can i get source code of multi hop clustering for wsn in ns2

For wireless mobile nodes VOIP is possible or not. If send me some program or link for VOIP program for wireless mobile nodes in NS2.35.Plz reply me...

hi,
i need source code for clustering and source prefix aggregation in wireless sensor network using tcl in ns2.please help me.

I have serveral nodes related files under /var/lib/ directory as shown below:

Code:

machine001.cluster.org 
machine002.cluster.org
machine003.cluster.org
machine004.cluster.org

I am trying to write a shell script which first finds out how many number of files are present in this directory. Then it should fetch the first name like machine001, machine002, machine003 etc. Then it should fetches ipaddress, hostname and netmask under machine001 first, then store it in some variable. Repeat this for all the nodes. How will the script look like?
