What are the security issues in WSN?
Some of these issues like snooping, sinkhole, tampering Sybil, clone, wormhole, spoofing, etc. affect the integrity, availability, and data confidentiality of the WSNs. Several security solutions had been proposed for WSNs; however, resource constraint of sensors makes some of these security solutions unfit for WSNs.
What is WSN PPT?
Introduction • A wireless sensor network (WSN) is a wireless network consisting of spatially distributed autonomous devices using sensors to cooperatively monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants, at different locations.
What is meant by tampering 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.
What is Web parameter tampering?
Description. The Web Parameter Tampering attack is based on the manipulation of parameters exchanged between client and server in order to modify application data, such as user credentials and permissions, price and quantity of products, etc.
How does misdirection affect the routing in sensor networks?
In misdirection attack intruder node misdirect packets away from the intended destination. Misdirection attack in wireless sensor network reduces the throughput of network along with the introduction of large end to end delay.
What are the types of WSN?
Generally, WSNs are classified into different categories like the following.
- Static & Mobile.
- Deterministic & Nondeterministic.
- Single Base Station & Multi Base Station.
- Static Base Station & Mobile Base Station.
- Single-hop & Multi-hop WSN.
- Self Reconfigurable & Non-Self Configurable.
- Homogeneous & Heterogeneous.
What are the major issues in WSN?
RESEARCH ISSUES AND CHALLENGES IN WSN Major issues that influence the structure and execution of a remote sensor organize are as per the following: Energy: Sensors require control for different activities.
What are the rules and policies of WSN?
In WSNs, different rules and policies are assigned to different sensor nodes; policies and rules dictate, which sensor node can read data from the surroundings, and which sensor node can send data to base station.
What are the factors that affect WSN security on chip?
Weather condition, e.g., rain, snow-fall, cold, and hot can affect the performance and life of WSNs. Humidity can destroy a node; rain-drop may corrupt the whole WSNs security on chip services. There is no security scheme that is 100% secure; it needs innovations.
Can a WSN work in hostile environments?
Node Level Security Some WSNs are designed to work in a hostile envi- ronment; it is not feasible for a human being visit those sites, and performs an attended operation, for instance, fire in wild-life, cold temperature zones, atomic reactors, and military operations.
