What are the different types of wireless sensor networks?

Classification of Wireless Sensor Networks

• Static and Mobile WSN.
• Deterministic and Nondeterministic WSN.
• Single Base Station and Multi Base Station WSN.
• Static Base Station and Mobile Base Station WSN.
• Single-hop and Multi-hop WSN.
• Self – Reconfigurable and Non – Self – Configurable WSN.
• Homogeneous and Heterogeneous WSN.

What is security in wireless sensor networks?

Security : One of the challenges in WSNs is to provide high-security requirements with constrained resources. The security requirements in WSNs are comprised of node authentication, data confidentiality, anti-compromise and resilience against traffic analysis.

What is tampering attack in WSN?

When sensor nodes of the WSN are compromised by an attacker, the WSN may suffer from data tampering attacks, that is, the attacker tampers with sensor readings to disrupt the normal operation of the network.

Which are the goal oriented attacks in WSN?

The primary goals are known as standard security goals such as Confidentiality, Integrity, Authentication and Availability (CIAA). The secondary goals are Data Freshness, Self- Organization, Time Synchronization and Secure Localization.

What is WSN explain the various application example of WSN?

Area monitoring is a common application of WSNs. In area monitoring, the WSN is deployed over a region where some phenomenon is to be monitored. A military example is the use of sensors to detect enemy intrusion; a civilian example is the geo-fencing of gas or oil pipelines.

What are the three basic technologies involved in WSN?

Among the standardized protocols we find Wireless M-Bus, KNX RF Multi, ZigBee and 6LoWPAN-based solutions (Wi-SUN and ZigBee IP).

Why security is a challenge in WSN?

Among the research issues in WSN, security is one of the most challenging. Securing WSN is challenging because of the limited resources of the sensors participating in the network. Moreover, the reliance on wireless communication technology opens the door for various types of security threats and attacks.

What is network security attacks?

What Is a Network Attack? A network attack is an attempt to gain unauthorized access to an organization’s network, with the objective of stealing data or perform other malicious activity.

What are the main challenges and attacks in WSN security?

Security, privacy, computation and energy constraints, and reliability issues are the major challenges facing WSNs, especially during routing. To solve these challenges, WSN routing protocols must ensure confidentiality, integrity, privacy preservation, and reliability in the network.

Which are applications of WSN?

Applications of WSN: Surveillance and Monitoring for security, threat detection. Environmental temperature, humidity, and air pressure. Noise Level of the surrounding. Medical applications like patient monitoring.

Why is WSN security required?

The WSN is facing a wide variety of security vulnerabilities due to the hardware limitations of the sensor nodes, wireless communication environment, real-time processing needs, heterogenic structure, large number of nodes, need for measurability, mobility, the weight of the application environmental conditions, and …

What is flooding attack in WSN?

Flood attacks are also known as Denial of Service (DoS) attacks. In a flood attack, attackers send a very high volume of traffic to a system so that it cannot examine and allow permitted network traffic.

What is Byzantine attack?

Byzantine attack is the attack performed by a fully trusted node that’s turned rogue and already has passed all the authentication and verification processes. When a trusted node is turned rogue, it can easily perform DoS attack on the media access control (MAC) layer to prevent other nodes from communicating.

What are the types of attacks in WSN?

So obligate the victim node to retransmit the data (exhaustion attack). retransmission of packet. attack, wormhole, and Identit y replication attack. Figure 6. Routing layer attacks in WSNs. all messages. In a hierarchical network of sensors, the parents’

Can wireless sensor networks be attacked in practice?

One of the moajor challenges wireless sensor networks face today is security, so there is the need for effective security mechanism .In this artical we investigate how wireless sensor networks can be attacked in practice.

What is WSN (wireless sensor network) routing layer attack?

Wireless Sensor Network (WSN) and its security concern play a vital part in its effecting functioning. WSN routing layer attacks pose a great threat to its functionality, whereas if a situation arises in which multiple attacks co-exist, then the scenario will become worse.

What are the design issues in different types of wireless sensor networks?

The design issues in different types of wireless sensor networks mainly include The topology issues of wireless sensor networks include the following. The major issues of a wireless sensor network include the following. These issues mainly affect the design and performance of the WSN.
