TL;DR

This paper analyzes security threats in wireless sensor networks (WSNs), categorizing attacks such as denial-of-service, sinkhole, and wormhole attacks, and proposes countermeasures including cryptographic protocols, anomaly detection, and trust-based mechanisms. The key contribution is a comprehensive taxonomy of WSN threats and practical defense strategies tailored to resource-constrained environments.

ABSTRACT

WSN is formed by autonomous nodes with partial memory, communication range, power, and bandwidth. Their occupation depends on inspecting corporal and environmental conditions and communing through a system and performing data processing. The application field is vast, comprising military, ecology, healthcare, home or commercial and require a highly secured communication. The paper analyses different types of attacks and counterattacks and provides solutions for the WSN threats

Motivation & Objective

• To identify and classify common security threats targeting wireless sensor networks (WSNs), including both internal and external attacks.
• To analyze the vulnerabilities of WSNs due to limited memory, processing power, and energy constraints.
• To propose effective countermeasures such as cryptographic authentication, intrusion detection, and trust management systems.
• To provide a framework for securing WSNs in critical applications like healthcare, ecology, and military surveillance.
• To bridge the gap between theoretical security models and practical deployment in low-resource sensor environments.

Proposed method

• Categorization of attacks based on network layer, data link layer, and application layer vulnerabilities.
• Design of lightweight cryptographic protocols to ensure data integrity and confidentiality in low-power nodes.
• Implementation of anomaly detection mechanisms to identify suspicious behaviors such as sudden traffic spikes or routing inconsistencies.
• Development of trust-based models to evaluate node reliability and isolate malicious or compromised sensors.
• Integration of end-to-end security policies across the WSN architecture to prevent common attack vectors.
• Evaluation of countermeasures through simulation and analysis of real-world deployment constraints.

Experimental results

Research questions

• RQ1 What are the primary types of attacks that compromise the security of wireless sensor networks?
• RQ2 How do resource limitations in WSNs exacerbate vulnerability to cyberattacks?
• RQ3 What lightweight defense mechanisms can be effectively deployed in memory- and energy-constrained sensor nodes?
• RQ4 How can trust and reputation systems improve resilience against internal node compromises?
• RQ5 What combination of cryptographic, detection, and policy-based controls ensures robust security in WSN deployments?

Key findings

• Denial-of-service attacks significantly degrade network performance by exhausting node energy and bandwidth.
• Sinkhole and wormhole attacks can be detected using time-of-flight measurements and multi-path routing validation.
• Lightweight cryptographic schemes reduce communication overhead while maintaining data confidentiality and integrity.
• Trust-based models reduce false positives in intrusion detection by filtering out unreliable or compromised nodes.
• Hybrid defense mechanisms combining encryption, anomaly detection, and trust evaluation outperform single-layer solutions.
• The proposed countermeasures are feasible for deployment in real-world WSNs due to low computational and energy overhead.
