A Comparison of Link Layer Attacks on Wireless Sensor Networks

Theory and Practice of Cryptography Solutions for Secure Information Systems

Wireless Sensor Network (WSN) is a promising technology that has attracted the interest of research in the last decade. Security is one of the fundamental issues in sensor networks since sensor nodes are very resource constrained. An attacker may modify, insert, and delete new hardware and software components to the system where a single node, a specific part of the sensing area, and the whole network may become inoperable. Thus, the design of early attack detection and defense mechanisms must be carefully considered. In this chapter, the authors survey attacks and their defense mechanisms in WSNs. Attacks are categorized according to the related protocol layer. They also investigate the open research issues and emerging technologies on security in WSNs.

— Wireless sensor networks have become a growing area of research and become more practicable solution to many challenging applications. Wireless Sensor Network is emerging technology with their limited energy and communication capabilities.WSN provides security and is particularly challenging and its mechanisms are also being the greatest concern to deploy sensor network and monitoring the real world application. The problem of security is due to the wireless nature of the sensor networks. Furthermore, wireless sensor networks have an additional vulnerability because nodes are often placed in a dangerous environment where they are not physically protected. The inclusion of wireless communication technology also incurs various types of security threats.

Wireless Sensor networks (WSN) is an emerging technology and have great potential to be employed in critical situations like battlefields and commercial applications such as building, traffic surveillance, habitat monitoring and smart homes and many more scenarios. One of the major challenges wireless sensor networks face today is security. While the deployment of sensor nodes in an unattended environment makes the networks vulnerable to a variety of potential attacks, the inherent power and memory limitations of sensor nodes makes conventional security solutions unfeasible. The sensing technology combined with processing power and wireless communication makes it profitable for being exploited in great quantity in future. The wireless communication technology also acquires various types of security threats. This paper discusses a wide variety of attacks in WSN and their classification mechanisms and different securities available to handle them including the challenges faced.

Security is a crucial service in wireless sensor networks that is becoming increasingly common in WSNs because wireless sensor nodes are typically deployed in an unattended environment, leaving them open to possible hostile network attack. Because wireless sensor nodes are limited in computing power, data storage and communication capabilities, any user authentication protocol must be designed to operate efficiently in a resource constrained environment. With a widespread growth in the potential applications of WSN, the need for reliable security mechanisms for them has increased manifold. Security protocols in WSNs, unlike the traditional mechanisms, need special efforts and issues to be addressed. The set of challenges in sensor networks are diverse, we focus on attacks on Wireless Sensor Network in this paper.

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.

A Wireless Sensor Networks (WSNs) are applied in numerous important applications in target of tracking, military, remote environmental monitoring, health care application, ecological, and many others. Wireless Network Systems consists of a large number of tiny sensor nodes which are typically deployed in hostile environments where they are encountered a large variety of malicious attacks. The role of these tiny sensors nodes are these sense data and process. Finally formulate to organize Wireless Sensor Networks. WSNs have limited constraints, includes limited energy resources, low power, less storage space and memory, low computation capability, and short communication range. Due to these constraints a great challenge in security comes to the research community. This article briefs a survey on security mechanisms and attacks in WSNs.

Wireless Sensor Network (WSN) is an emerging technology that consists of spatially distributed autonomous sensors to monitor physical or environmental conditions. These networks are useful in several applications such as health monitoring, wildlife monitoring, area monitoring, traffic monitoring, emergencies, environmental control, industrial quality control, distributed robotics, military command, intelligent commutations, examining human heart rates etc. Security is a fundamental requirement for these types of networks.

Wireless Sensor Networks (WSNs) are employed in numerous applications in different areas including military, ecology, and health; for example, to control of important information like the personnel position in a building, as a result, WSNs need security. However, several restrictions such as low capability of computation, small memory, limited resources of energy, and the unreliable channels employ communication in using WSNs can cause difficulty in use of security and protection in WSNs. It is very essential to save WSNs from malevolent attacks in unfriendly situations. Such networks require security plan due to various limitations of resources and the prominent characteristics of a wireless sensor network which is a considerable challenge.
