A Low Power WSNs Attack Detection and Isolation Mechanism for Critical Smart Grid Applications

Wireless sensor networks (WSNs) are effective tools in many smart grid applications such as remote monitoring, equipment fault diagnostic, wireless advanced metering infrastructure, and residential energy management. WSNs are attractive tools due to their low cost, dynamic nature, ruggedness, and low-power profile. Maintaining a low-power profile is a critical design factor in WSNs. Therefore, implementing sophisticated quality of service protocols and security mechanisms in WSNs is a challenging task. Furthermore, WSNs security mechanisms should not only focus on reducing the power consumption of the sensor devices but also they should maintain high reliability and throughput needed by smart grid applications. In this paper, we present a low-power cyber-security mechanism for WSNs-based smart grid monitoring applications. Our mechanism can detect and isolate various attacks such as the denial of sleep, forge, and replay attacks in an energy efficient way. The simulation results show that our mechanism can outperform existing techniques in power efficiency while maintaining constant delay and reliability values.

Applied Technology for Typical Attacks and Security Mechanisms in Wireless Sensor Networks

Wireless Sensor Networks (WSNs) are used in many applications in military and commercial areas. These applications often include the monitoring of sensitive information such as enemy movement on the battlefield or the location of personnel in a building. However, due to the highly resource constrained in sensor nodes, traditional security strategies always can do few with attacks on WSNs. In this Paper, we proposes a study of attacks and security mechanisms in WSNs. First, we summarize the attacks to WSNs and the security requirements based on the TCP\IP networking model, then we present the security solutions to each attack. Along the way we highlight the advantages and disadvantages of various WSN solutions and further compare and evaluate these solutions.

A Survey on Wireless Sensor Network Security

Wireless sensor networks (WSNs) have recently attracted a lot of interest in the research community due their wide range of applications. Due to distributed nature of these networks and their deployment in remote areas, these networks are vulnerable to numerous security threats that can adversely affect their proper functioning. This problem is more critical if the network is deployed for some mission-critical applications such as in a tactical battlefield. Random failure of nodes is also very likely in real-life deployment scenarios. Due to resource constraints in the sensor nodes, traditional security mechanisms with large overhead of computation and communication are infeasible in WSNs. Security in sensor networks is, therefore, a particularly challenging task. This paper discusses the current state of the art in security mechanisms for WSNs. Various types of attacks are discussed and their countermeasures presented. A brief discussion on the future direction of research in WSN security is also included.

Security issues of wireless sensor networks in healthcare applications

The emergence of wireless sensor networks (WSNs) in healthcare applications is gaining momentum through the increasing array of wearable vital sign sensors and location tags which can track both healthcare personnel and patient status/ location continuously in real-time mode. Despite the increased range of potential application frameworks — ranging from pre-hospital, in-hospital, ambulatory and home monitoring, to long-term database collection for longitudinal trend analysis — the security gap between existing WSN designs and the requirements of medical applications remains unresolved. Generally, WSN devices are extremely limited in terms of power, computation, and communication. They are often deployed in accessible areas, thus increasing security vulnerabilities. The dynamic ad hoc topology, multicast transmission, location awareness, critical data prioritisation, and co-ordination of diverse sensors of healthcare applications further exacerbate the security challenges. This paper presents an analysis of various WSN security mechanisms from the demanding perspective of healthcare applications, and considers the importance of security to the successful deployment of pervasive computing solutions in the healthcare industry.
