What are security issues in WSN?

There are several security and privacy issues associated with multi-hop routing. Some of these issues like snooping, sinkhole, tampering Sybil, clone, wormhole, spoofing, etc. affect the integrity, availability, and data confidentiality of the WSNs.

What are the attacks in wireless sensor networks?

A WSN with 100 sensor nodes. Network layer WSNs use a communication multi-hops for routing the packets towards the destination, the attacks in this layer are: black hole, selective forwarding, Sybil attack, HELLO flood attack, wormhole, and Identity replication attack.

What are the security requirements of wireless sensor networks?

The so far listed security requirements of WSN are data confidentiality, data integrity, data freshness, and data authentication and availability [12–15].

How security is distributed in wireless sensor network?

WSNs are autonomous and are distributed in space. Due to the absence of central authority and random deployment of nodes in the network, WSN is prone to security threats. Well-known attacks in WSN are a malicious attack (such as compromised node imitating as one of the network nodes, misleading other nodes).

What links sensor networks to other networks to deliver data?

The Gateway acts as a bridge between the WSN and the other network. This enables data to be stored and processed by devices with more resources, for example, in a remotely located server. A wireless wide area network used primarily for low-power devices is known as a Low-Power Wide-Area Network (LPWAN).

What is wireless sensor network Mcq?

This article lists 100+ Wireless Sensor Network MCQs for engineering students. Wireless Sensor Network is also represented as “WSN” and it is a group of dedicated sensors that are spatially dispersed to records, monitors physical environmental parameters, and organizes that data at a central location.

What is network security attacks?

Network attacks are unauthorized actions on the digital assets within an organizational network. In passive network attacks, malicious parties gain unauthorized access to networks, monitor, and steal private data without making any alterations. Active network attacks involve modifying, encrypting, or damaging data.

Which route user queries or commands to appropriate nodes in a sensor network?

Q. ___________routes user queries or commands to appropriate nodes in a sensor network
B. bridge only
C. gateway only
D. none of above
Answer» c. gateway only

Why security is important 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 kind of security support does leap provide in wireless sensor networks?

LEAP is designed to support secure communications in sensor networks; therefore, it provides the basic security ser- vices such as confidentiality and authentication. In addition, LEAP is to meet several security and performance require- ments that are considerably more challenging to sensor net- works.

How wireless sensor networks is used in society?

Wireless sensor networks (WSNs) provide an indispensable sensing and actuation platform in a wide variety of cyber-physical infrastructure and systems, such as smart metering of electric grids, distance and speed monitoring of vehicles in transportation systems, environment and health monitoring, security and …

What are the security vulnerabilities in wireless sensor networks?

One major Security Vulnerabilities In Wireless Sensor Networks: A Survey defensive measure against such attacks is the usage of small frames, so that any individual node seizes the channel for a smaller duration only.

What is a wireless sensor network used for?

Abstract—Wireless Sensor Networks (WSNs) have facilitated human life in different fields: medical, engineering, agriculture, environment, traffic, and military. WSNs are extensively used in monitoring, tracking, and controlling applications; however, their resource constraint nature faces new challenges.

What are the key features of WSN?

These are: centralized management, device heterogeneity, routing protocols, node’s mobility, information privacy, and limited computational-power. WSN spans over a large geographical area; therefore, they must address the issue of routing-protocols, scalability, communication, and security.

Why do sensors need to be aware of their position?

Knowledge of the position of the sensing nodes in a WSN is an essential part of many sensor network operations and applications. Sensors reporting monitored data need to also report the location where the information is sensed, and hence, sensors need to be aware of their position.
