Energy Efficiency and Security in Wireless Sensor Networks
Fields like health, environment, and energy use wireless sensor networks (WSNs). Sensor nodes gather data from their surroundings, performing local computations. Improper use leads to substantial energy drainage.
Each sensor node in the wireless network system is equipped with a battery. You can not change the battery every time. You can also not recharge the battery every time. What can you do? You can only conserve energy by exploring those effective ways that can enhance energy efficiency and security in wireless networks. In addition to it, the unprotected communication route of the sensory nodes can show challenges in its security.
Where do people use wireless sensor networks?
Wireless sensor networks perform local computations on various factors like humidity, vibrations, seismic events, temperature, etc., gathering crucial geographical information.
What are the sources of energy waste in wireless sensor networks?
Wireless sensor networks do local computations based on the information provided by the surroundings. Their sensor nodes are recharged with batteries. But sometimes the batteries get dead due to energy waste. There are many reasons why energy waste happens. Some of the reasons are given below:
Wireless sensor networks have idle channels. If you have activated idle channels, you will find out that the batteries of the sensor nodes have drained fast.
A sensory node should receive one packet at one time to give better outcomes. If two or more packets are received by sensory nodes, then, they become the cause of collision.
It may be possible that the sensory node is receiving the signals of other nodes. This overhearing is the cause of energy waste.
If you are using the maximum number of control packets, you have to bear the problem of battery drainage soon.
What can you do to enhance energy efficiency in wireless sensor networks?
You can apply some ways to do energy efficiency in wireless sensor networks.
When the wireless sensor network isn’t communicating, set the radio receiver to low-power sleep mode. Also, turn off the radio when data transmission isn’t required.
You can switch off those nodes that are not required.
What security problems can persist in wireless sensor networks?
Many security issues can persist in wireless sensor networks. Some of the security issues have been discussed below:
The intelligent devices are installed at various places in the wireless sensor networks. Attackers exploit this, changing or replacing nodes, making it hard to differentiate real ones from the false ones they’ve inserted. In this way, they can procure crucial information from the stolen security nodes.
Sensory nodes are deployed at insecure places to detect sensory changes in the surroundings. Where there is nobody who can inspect anything, it becomes easy for the attackers to inject false data into the nodes.
- Lack of a secure communication channel allows attackers to access information easily. Attackers mimic real nodes, sending false signals to steal secret data from private nodes.
- Wireless Sensor Networks have become subject to cyber-attacks. Cybercriminals used to send fake emails and messages.
- The attackers might try to steal personal credentials. After getting them, they can access the network data.
How can security be enhanced in wireless sensor networks?
In wireless sensor networks, some security threats are persisting. Maximize threat prevention with these security measures:
Soft message encryption can help your security nodes to achieve security at the advanced level. Through this, a message is divided into several parts. In this way, the divided parts are encrypted.
The communication route should be secured. This will help your system in having uncompromised security.
Put the unused sensory nodes on sleep mode.
The goal is to enhance energy efficiency and security in the wireless sensor network. Manager nodes need to confirm data authenticity, ensuring it’s from a reliable source, not malicious attackers. They shouldn’t rely on a verification table. Utilizing a shared key between communication nodes safeguards their exchanges. If a sensor is lost, the WSN should permanently block it to prevent credential reuse.
Sensor credentials require consistent updates for security reasons.
Applications Across Industries: Wireless sensor networks (WSNs) find extensive application in diverse sectors such as environmental monitoring, healthcare, industrial automation, and smart infrastructure due to their data collection and transmission capabilities.
Security Measures: Enhancing WSN security involves manager nodes verifying data sources for authenticity, ensuring received information is from trusted sources. Relying on methods beyond verification tables strengthens security protocols.
Optimizing Energy Efficiency: Efficient use of energy is crucial in WSNs. Techniques like putting the radio receiver in low-power sleep mode when not in use and turning off radios during inactive transmission periods help conserve energy.
Secure Communication: Utilizing shared keys between communication nodes fortifies data confidentiality and integrity during transmission, preventing unauthorized access and data tampering.
Loss Prevention Measures: In the event of sensor loss, it’s essential for the WSN to permanently block the compromised sensor. This prevents potential security breaches through unauthorized access or credential reuse.
Data Integrity and Reliability: By implementing these security measures, WSNs ensure data integrity, reliability, and confidentiality, fostering trust in the transmitted information across various applications and industries.
Implementing these measures strengthens the overall effectiveness and reliability of wireless sensor networks, making them more robust, secure, and efficient in their operations.
