An Enhanced Source Location Privacy based on Data Dissemination in Wireless Sensor Networks (DeLP)

Area of Science:

• Computer Science
• Network Security
• Wireless Sensor Networks

Background:

• Wireless Sensor Networks (WSNs) are vulnerable to eavesdropping, compromising source location privacy.
• Adversaries can trace packets to identify the originating node in exposed WSN environments.
• Existing security measures may not sufficiently protect contextual privacy in WSNs.

Purpose of the Study:

• To develop and evaluate an enhanced three-level security system for source location privacy in WSNs.
• To address the problem of eavesdropping and packet tracing in WSNs.
• To improve the overall performance and security of WSNs.

Main Methods:

• A three-level security system involving flooding nodes and fake/phantom nodes for confusion.
• Deployment of fake nodes in opposite quadrants and phantom nodes in other quadrants.
• Utilizing the Dissemination in Wireless Sensor Networks (DeLP) scheme.

Main Results:

• DeLP reduced energy utilization by 50% compared to tree-based schemes.
• The safety period increased by 26% and packet delivery ratio improved sixfold.
• Packet delivery delay decreased by 15% with DeLP.
• DeLP offered a 334% longer safety period than phantom routing.

Conclusions:

• The proposed three-level security scheme effectively protects source node privacy in WSNs.
• DeLP demonstrates significant improvements in energy efficiency, safety period, packet delivery ratio, and delay.
• The DeLP scheme provides a robust solution for enhancing location privacy in WSNs.
