The First Assignment Of WSN Course ( The Second Paper To Learn )

On Tuesday, 22 September 2015, My Lecturer gave an assignment on his course. He gave us the soft copy of seminar proceding which contain 23 paper collection about WSN.

So, This is the soft copy, File size 17.3 MB

Cover of Seminar Proceding

Among many paper, my lecturer told us to choose one of the paper, According to name list of class, i got short paper which title :

Implementation and Experimentation of Industrial Wireless Sensor Actuator Network Protocol ( click here )

This paper so very different with previous paper. In this paper concern to explain about Wireless Sensor Actuator Network ( WSAN ) Which ussualy aplicable in industrial appliance. Even Though my research plan is about Consensus Estimation On WSN.

I think its so fine because i haven't much knowledge about WSN. It will be important thing for me.

So

Information about this paper according my understanding is :

1) Author Name : Mo Sha, Dolvara Gunatilaka, Chengjie Wu, and Chenyang Lu.

2) Title Of Paper : 

Implementation and Experimentation of Industrial Wireless Sensor-Actuator Network Protocols.

3) Source : 

12th European Conference, EWSN 2015 Porto, Portugal, February 9–11, 2015 Proceedings.

4) Summary Of Reported Research :

Process automation is very important in various industrial fields . Generally, the industry used a network cable to connect sensors, actuators and the control room as automation component for continuity production processes . Surely cable systems have many disadvantages. Among others is high cost installation and maintenance. Beside that is difficulty of placement and reconfiguration cable. So this make difficult to facilitating new production process especially technical demand.

Wireless Sensor Actuator Networks ( WSANs ) is highly recomended because it does not use the cable for data communications and power source. One of product WSANs is WirelessHART.

In industrial standart, An ability that must handle by WSANs is e.g

>> Network must supporting two routing method, That are " Source Routing " which provide single route for each data flow. And " Graphic Routing " which provide redundant data flow.

>> Network must using multi chanel Time Division Multiple Access ( TDMA ) on MAC layer above IEEE 802.15.4 for physical layer. This order to only one transmission on schedule slot.

Critical result of this paper is WirelessHart capable to supporting two routing method "Source Routing " and " Graphic Routing ".  Graphic routing is more better in term of reliability, Latency and energy consumption.

5) Strength Of Invention:

On previous paper generally explain about WSANs but only term of theoritical about routing and latency. In this paper explain about real application of WSANs on WirelessHART. Many problem but nothing explain before especially " Graphic Routing ".

6) Weakness :

Using Dijkstra’s shortest-path algorithm and Monotonic Scheduling algorithm but nothing formula or equation to explain about algorithm. I think this paper explanation very less theoritical.

7) Limitation:

The research of conducted is Implementing WirelessHART protocol with TinyOS 2.1.2 and TelosB motes. Using Dijkstra’s shortest-path algorithm to generate routes for source routing. The schedule generator uses rate Monotonic Scheduling algorithm to generate transmission schedules. Developed a multi-channel TDMA on MAC protocol. Finally comparating two routing method.

In our assignment, Every student in the class presenting summary of each paper chosen. Each student was given two minutes to presenting their summary. But mostly student spent more three minutes even more. It make my lecturer rather annoyed.

From this paper, something that should be known or just know is :

1) What different from WSN and WSAN ?

2) What is WirelessHART ?

3) What is TDMA, CSMA and several other.

4) MAC Layer and Network Layer.
