New swarm intelligent algorithm will be implement

After attend talk by Prof. Abbas Jamalipour at UPM today then I got inspire from his speech. It was about new algorithm on swarm intelligent technique to solve network problem. One of the method is how Bee worker communicate with each other and how their distribute their job like queen bee, worker bee, soldier bee & etc. He also tell about another method which is ant algorithm & how the way they searching path or route to their food. So I will try to propose implement his idea to my new algorithm, perhaps it can solve some issue...

New algorithm give a lot off effect on dropped packet

After I satisfy for extended life time for battery of WSN router. It also need to look up on dropped packet using trace graph. Then I realize that when certain node is push to sleep mode if I cannot reroute properly than a lot of dropped packet will happen. He I show that quite a lot of dropped packet compare than other routing protocol.

New algorithm with more than 3000 sec.

I try new algorithm with more than 3000 sec. it was suggested by Assoc. Prof. Dr. Norashidah. Then suddenly I saw that my algorithm is not good enough to save energy for long term utilization. Then I do some modification that to be fair for all intermediate nodes. So I come out with new method where every intermediate node will have same time of sleep. To calculate that we record when 1'st node come to sleep then until the last node start to sleep. So the same duration will apply to other intermediate nodes.
Some sort like this:

∑ sleep time = Time last node sleep - Time 1'st node sleep
Time node i wake up = Time node i sleep + ∑ sleep time

Then the result change where new method can save more energy compare with other routing protocol.

AWK file solution for JTrana

Last mid night while working with Zul, I just only thinking how to solve problem of wasting time waiting JTrana process. The problem is when we want to show energy graph it take about half to 1 day for analyzing trace file. Like example when I set simulation time until 3000 second then size the trace file increase up to 0.5 Gbyte produce long time to analyze. Then our greatest sifu Zul come to introduce how to use AWK file. Then after few basic step he teach me, I realize that with AWK script file can solve problem waiting from 1 day become few second. I so wonderful, how most great Allah introduce someone like him to me.

Library modular define in C short course

Last week I attend short course teached by our sifu Madam Marina, she was one of C programming sifu in CoIT. It was very nice to know how library modular define work. One long program can be divide by 3 main file:
  1. Header file (for global variable, function declaration, constant)
  2. Application file (for main body)
  3. Implementation file (for function definition)
Each of this file have their own function to make the program more easier. If you interested to learn you can log in Here

Dropped packet for new routing strategy but still maintain same as existing RP

Again I look on dropped packet for new energy strategy give same amount dropped packet with DSDV routing algorithm. So here I can conclude that our new strategy is still not bad. This is 1'st our objective achievement where we concentrating improvement on energy. The result:

New energy routing strategy give side effect on packet delay

After I try new energy routing strategy on my simulation environment that can give advantage on remaining energy. But then when I look at packet delay show that new strategy effected. It is because after one or two intermediate nodes in sleep mode where data from source node have to go through long way until reach access point. Here the result:


We can see 3 out of 5 nodes the new algorithm is better which is node1, node 2 and node 7 but two more nodes effected cause of new energy routing strategy. So now I need to fine another way that can improve in this problem...

Energy saving strategy worked ... !

After I start testing our energy strategy on simulation environment. We can see from 1'st result that show some improvement on energy saving on remaining energy. Then after compare with original simulation without energy strategy, our claim that it can prolong energy life time of battery.



Further more there is need to check whether this energy strategy can ensure network performance always in good condition...

Flow chart new method

Today I want to introduce new method in energy saving strategy. It was focus on intermediate node, where each node rotating shift sleep mode due to prolong remaining energy. Here I show where we got 2 level of energy threshold value where 70% and 35% of remaining energy. Any intermediate node will change to sleep mode when 70% of remaining energy or level 1 threshold value accord. But if all intermediates node exceed level 1 threshold value, the threshold value itself will change to level 2 threshold value where until 35% of remaining energy. Then the same process apply to intermediate node.

Set node to idle/sleep state

To further our routing algorithm, there is need to do some saving energy where the specific node can be force to sleep or idle modes. Our focus is in intermediate node where the node will always exhaust energy because of forwarding data from source node to destination node. But working with NS-2 with physical layer mac 802.11 there is no basic command that can set node to be sleep/idle. The node itself can sleep/idle when there no activity sending or receive data on node. So there is need to figure out some alternative way to make the node force to sleep.

2'nd conference attended

It was 2'nd conference I had. The environment very common where nothing so exited. The audience to small. All of them was presenter it's self. I never get any question from audience during my presentation, but it very nice when we can gather with all researcher in Malaysia with difference background i.e. medicine, ICT, engineering, physic & chemical etc.

MSTC (COSTAM) paper ready


After I complete writing this conference paper, to get a sponsor by project fund the paper it's self need to be review by college panel. Then the paper has to return back to me, to do some modification work on the mistake that I did. Then the paper now ready to be fund and to be present in these respective conference…

Dear God, syukur for everything that I had.

Programmer-defined Library

Now I want to concentrate on how to create our own algorithm, some detail need to clearify i.e. what thing need to implement for our algorithm. Working in NS-2 there are limitation thing we can do in TcL language. But for our case we need to edit in C++ method where new library to be introduce.
We create our own programmer-define libraries to further modularize our program. Some brief about programmer-defined library. In library contain some general purpose function that we aspect to use in future application. Then after we clarify them pun in one library and implement them, we can use in other projects, just we use in standard library functions in many other programs.

NSF sponsor

Salam, everyone
Quite long since I not updating my blog because of many thing need to do.
Yesterday I call MOSTI to ask about my NSF application.
Then they spoke to me that I success to get NSF scholarship.
Wow it was the best news in 2008 that I have.
Now I don't have to think about my financial problem and then I can only to concentrate about my research.


P/S:
For Syikin and Fadilah I wish you good luck for your application.
When during your interview session stay calm and always trust on your capability, you can do it, never give up....

S.M.A.R.T Goals

I got some article from Sumay blog perhaps it can motivate some thing for our survival work...

Specific
Measurable
Attainable
Realistic
Timely

Specific - A specific goal has a much greater chance of being accomplished than a general goal. To set a specific goal you must answer the six "W" questions:
*Who: Who is involved?
*What: What do I want to accomplish?
*Where: Identify a location.
*When: Establish a time frame.
*Which: Identify requirements and constraints.
*Why: Specific reasons, purpose or benefits of accomplishing the goal.
EXAMPLE: A general goal would be, "Get in shape." But a specific goal would say, "Join a health club and workout 3 days a week."

Measurable - Establish concrete criteria for measuring progress toward the attainment of each goal you set. When you measure your progress, you stay on track, reach your target dates, and experience the exhilaration of achievement that spurs you on to continued effort required to reach your goal.
To determine if your goal is measurable, ask questions such as......
How much?
How many?
How will I know when it is accomplished?

Attainable - When you identify goals that are most important to you, you begin to figure out ways you can make them come true. You develop the attitudes, abilities, skills, and financial capacity to reach them. You begin seeing previously overlooked opportunities to bring yourself closer to the achievement of your goals.
You can attain most any goal you set when you plan your steps wisely and establish a time frame that allows you to carry out those steps. Goals that may have seemed far away and out of reach eventually move closer and become attainable, not because your goals shrink, but because you grow and expand to match them. When you list your goals you build your self-image. You see yourself as worthy of these goals, and develop the traits and personality that allow you to possess them.

Realistic - To be realistic, a goal must represent an objective toward which you are both willing and able to work. A goal can be both high and realistic; you are the only one who can decide just how high your goal should be. But be sure that every goal represents substantial progress. A high goal is frequently easier to reach than a low one because a low goal exerts low motivational force. Some of the hardest jobs you ever accomplished actually seem easy simply because they were a labor of love.
Your goal is probably realistic if you truly believe that it can be accomplished. Additional ways to know if your goal is realistic is to determine if you have accomplished anything similar in the past or ask yourself what conditions would have to exist to accomplish this goal.

Timely - A goal should be grounded within a time frame. With no time frame tied to it there's no sense of urgency. If you want to lose 10 lbs, when do you want to lose it by? "Someday" won't work.
But if you anchor it within a time frame, "by May 1st", then you've set your unconscious mind into motion to begin working on the goal.
T can also stand for Tangible - A goal is tangible when you can experience it with one of the senses, that is, taste, touch, smell, sight or hearing. When your goal is tangible you have a better chance of making it specific and measurable and thus attainable.

Power cosumption using Jtrana

WSN is one routing protocol algorithm that depend on battery as power supply. Every strategy of routing protocol need to plan in order to save battery power as much as possible. This is because of by focus on energy consumption we can ensure the live spend of battery will be prolong. However to save battery energy it got limitation where average delay and throughput for the network must in acceptable range. But for let we see what existing routing algorithm can give in order to save power consumption.

Here there are some example simulation and result show power consumption by Jtrana:


Here node 0 where act as access point to collect data from common node


Here example one of common node where the power consumption less than access point
We are now compare between three routing algorithm, we are only focus on access point because from our observation show access point will always use large of energy consumption. So we make it more than other common nodes.

Protoname routing protocol with 10 nos of nodes

After I success installing new routing protocol call Protoname the I want to try these routing protocol performance, I try the same situation there are:


1.Scenery size350 meters X 350 meters
2.Transmission range175 meters
3.No. of node9 nodes (8 common nodes & 1 sink node)
4.Routing ProtocolProtoname (New protocol)

Then the result is:

Sent packet

Receive packet

Dropped packet




Lost packet

Abstract for national and international conference paper..

My supervisor, Mr Suhaimi ask me to propose paper conference for represent of our group, then I try to search from previous email where our RMC director Assoc. Prof Dr. Md Zaini and other have sent 2 or 3 notice about call for paper conferences before.
But before that the question mark is what result need to include and it is that result enough to be accept in that conference. Whatever the is thing I need to do it no matter how....
