Seminar Assignment ( Third Paper To Learn )

On Tuesday, 6 October 2015, My Lecturer gave an assignment again on his course. He told to us to searching paper about energy saving in WSN and then submit in national seminar. Our assignment in groups. One group there were three student. I grouped with senior student.

We chose the paper that we think not difficult to learn and relevant enough with assignment topic.

this is paper that we chose. File size 294 KB.

Two Energy-Efficient Cluster Head Selection Techniques Based on Distance for Wireless Sensor Networks. ( click here )

So, Information about this paper according my understanding is

1) Author Name : Tri Gia Nguyen, Chakchai So-In, Nhu Gia Nguyen

2) Title Of Paper : 

Two Energy-Efficient Cluster Head Selection Techniques Based on Distance for Wireless Sensor Networks.

3) Source : 

2014 International Computer Science and Engineering Conference (ICSEC).

4) Summary Of Reported Research :

This paper propose two routing protocol. Cluster Head ( CH ) is leader for nodes in one cluster which select base on distance and distance combine with energy residual.

DB LEACH implementing selecting Cluster Head base on distance parameter only. Different with DBEA LEACH which implementing selecting Cluster Head ( CH ) base on distance and energy residual.

DB LEACH and DBEA LEACH more efficient in term of energy than many varian of LEACH like T LEACH, K LEACH and of course LEACH. And DBEA LEACH is the most efficient among. DBEA LEACH make better conserving energy and guarantee longer network lifetime.

Number Of Dead Nodes

5) Strength Of Invention:

This paper propose two routing protocol to energy saving on WSN. That are DB LEACH and DBEA LEACH. Both of them is better if compare with another Varian of LEACH.

6) Weakness :

Author said, "Although our proposals can achieve performance improvements, still many aspects of its design need to be investigated using heterogeneous scenarios and constraints such as quality of service aware mechanisms, encoding and compression techniques, multi-levels transmissions, and complex clustering models. Also, since there are other factors that may affect the energy consumption, comprehensive simulation and analysis could be further investigated".

I think many critical case for further research about WSN energy saving. Many problem that author said are close relation to the development of LEACH Varian.

7) Limitation:

In this paper compare five varian of LEACH among other is LEACH, K LEACH, T LEACH, DB LEACH and DBEA LEACH. Using software MATLAB to simulating several parameter environment size 100 x 100 meter, All nodes have first energy parameter 0,1 Joule. And probability node become Cluster Head is 0.05.

From this parameter, the goal is get data about:

>> How many number of dead nodes ?

>> How many number of Cluster Heads ( CH ) ?

>> And How long network life time? This can be seen from sum energy of all nodes when last round.

From This paper i was learn another problem in WSN Topic. Main problem is how to saving energy. But the sub problem is tvery diverse.
