What is wireless sensor network security?

What is wireless sensor network security?

Wireless Sensor Network (WSN) is a combination of hardware and software network that uses a system of sensors to detect physical phenomena. WSN is being widely used in industrial and consumer applications. Privacy is a key factor of WSN, it is imperative to secure data that is used, transmitted, or stored.

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 is node in WSN?

8.5. Sensor nodes in a wireless sensor network (WSN) measure environmental parameters and transmit the data back to a network gateway where it is aggregated, stored, and processed. Sensor nodes are usually battery operated and deployed in large numbers in difficult to reach places.

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.

What are the basic design issues of wireless sensor network architecture?

Energy Consumption It is one of the major issues in wireless sensor network. Sensor nodes are equipped with battery that is used as their energy source. The sensor network can be deployed in hazardous condition so it becomes difficult recharging or changing batteries.

What are the different components of sensor nodes?

A sensor node is made up of four basic components such as sensing unit, processing unit, transceiver unit and a power unit which is shown in Fig. 5. It also has application dependent additional components such as a location finding system, a power generator and a mobilizer.

What are the components of sensors?

Sensors, in their most general form, are systems possessing a variable number of components. Three basic components have already been identified: a sensor element, sensor packaging and connections, and sensor signal processing hardware.

What are wireless sensor networks and how it works?

Wireless Sensor Networks (WSNs) can be defined as a self-configured and infrastructure-less wireless networks to monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants and to cooperatively pass their data through the network to a main location or sink where the data can be observed and analysed.

What are the future uses of wireless sensor networks?

The Rise of Wireless Sensor Networks across Industries Communications. Fifth Generation Cellular Technology or 5G is the latest contribution of the communications domain in the Industrial Revolution 4.0. Transportation. Agriculture.

How does a wireless sensor network work?

Wireless sensor network. A wireless sensor network consists of spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, pressure, etc. and to cooperatively pass their data through the network to a main location.

What is LTE network architecture?

LTE Network Architecture. The high-level network architecture of LTE is comprised of following three main components: The User Equipment (UE). The Evolved UMTS Terrestrial Radio Access Network (E-UTRAN). The Evolved Packet Core (EPC). The evolved packet core communicates with packet data networks in the outside world such as the internet,…
