About My Project...

As i early mentioned, I am a B.E fresher....Now i want to discuss with you about my project which i done in my final year engineering. The title of my project is "Quarantine Region Scheme to mitigate spam attack in sensor network". Its really a nice and interesting project. My deportment professor Mrs.Shiheena guided me. This projects concentrates on Sensor area. Because the sensor network are easily deployable. This project enables and increase the security and integrity in sensor area. Even though there is so many projects developed for sensor network security, but my project quite different because of the following reasons

• In the earlier projects, Authentication process takes place on every node but in this project, the authentication takes place only in the quarantine region.
• Hash based authentications is used in our project, because of this the process will fast at the same time very simple.

There are 5 modules in this project, they are....

• Node creation
• Node processing
• Status checking
• Authentication
• Sink node process
  

First we are doing self authentication, if any spam found means we forms an quarantine region with that afflicted node(Anti-node) and adjacent nodes. And doing authentication for only those node unlike fully. Because of this, time and battery power saved and also communication cost..... What you guys think about my project.....

Technical Questions...

Hi friends, Here i am going to share some important technical questions which i encountered in my interviews. I am B.E computer science degree holder, In my college there is so many placement programs organized by top companies.The names of some of those companies are CTS , TCS , Infosys , Wipro , US Technology , Caritor nad so on. I attended more than 15 interviews, the more special thing was so many companies asked technical questions similarly.... So here i am going to share those questions with you. If you are a B.E(computer science or IT or ECE) student, then go through the following questions.....

• What are the difference between C and C++?

• Difference between "While" and "do-while"?

• Explain the pointer concept in C?

• File concept in C?

• What is class?

• What is Object?

• Opps concept in C++?

• What is mean by data Abstraction and Polly morphism?

• Basic features of Java?

• What is "Data Structures"?
  

• Explain the pipe lining concepts?

• What are the seven layers of networking?

• What are the important sorting techniques and explain shortly?

• Explain data mining?

• What is OS and explain it?

• Explain about threading and Scheduling?

• What are the types of SQL schemes in database?

• Explain Data warehouse?

• What are all the difference between two-tyre and Three-tyre mechanism in database?

• Tell me briefly about your project?

Above are the questions which i encountered in my interview. What you guys thinking about my question list, If you have any other questions which i missed please sent those questions to me.... i ll update those questions...
