Protecting Location Privacy in Sensor Networks Against a Global Eavesdropper

Abstract:

While many protocols for sensor network security provide confidentiality for the content of messages, contextual information usually remains exposed. Such information can be critical to the mission of the sensor network, such as the location of a target object in a monitoring application, and it is often important to protect this information as well as message content. There have been several recent studies on providing location privacy in sensor networks. However, these existing approaches assume a weak adversary model where the adversary sees only local network traffic. We first argue that a strong adversary model, the global eavesdropper, is often realistic in practice and can defeat existing techniques. We then formalize the location privacy issues under this strong adversary model and show how much communication overhead is needed for achieving a given level of privacy. We also propose two techniques that prevent the leakage of location information: periodic collection and source simulation. Periodic collection provides a high level of location privacy, while source simulation provides trade-offs between privacy, communication cost, and latency. Through analysis and simulation, we demonstrate that the proposed techniques are efficient and effective in protecting location information from the attacker.

Problems in this project:

  Ø  This simulation project cannot be done as a final year project.

 Ø  Creation and maintenance of nodes is impossible in short term projects.

 Ø  The sensors cannot be used because it costs more.

Ø  This graph analysis is unreal because the movable nodes cannot be furnished.

Reasons for declaring this project as fake project:

Ø  This project cannot be implemented by a final year student because it costs more to buy sensors.
Ø  Also the nodes pose a great risk of failure and node property changes.
Ø  This project will not be a real project and it won’t work in the real environment because of unavailable wireless network and dedicated signals for communication.
Ø  Hence the students are suggested not to take this as their project.

Suggestions to complete this project as genuine project:

Ø  This is a research project to be implemented and tested well and hence requires more cost and more time.
