This research presents a newly proposed design for a reliable protocol for wireless sensor networks, supporting large-scale smart farms. The protocol was tested and compared with previous methods. The results demonstrated a significantly higher data transmission success rate and a transmission speed approximately three times faster. Additionally, when the proposed reliable protocol was implemented in ten smart farms in Sukhothai province, it achieved a data transmission success rate of 99.07% and an average transmission time of 16.64 seconds, approximately three times faster than the previous method. These experimental outcomes confirm that the proposed reliable protocol meets the communication objectives outlined in its design, ensuring reliable, consistent, and timely data transmission.

A new automatic cultivation system was proposed using a forecasting algorithm for environmental control. Information used for the forecast was taken from real time data obtained by a wireless sensor system. The objective was the automation of suitable environmental cultivation methods. The proposed forecasting algorithm used historical data to predict future environmental control according to its goals. A real system was implemented and constructed to test the hypothesis. Results showed that the system had the required features. Environmental controls of the original system were compared with the proposed algorithm according to the created thresholds. The proposed forecasting algorithm controlled humidity in the soil at 98.26%, while the original system recorded do 69.33%, with humidity in the air controlled at 93.87% compared to the original system at 48.96%. This algorithm will be very useful to promote sustainable agriculture.

A novel optical checksum high speed approach for error detection is proposed for use in a multi tunnel wavelength domain. By using this technique, all processes were performed by passing light through optical hardware (PANDA ring resonator together with add/drop filter). Outputs achieved from dynamic states utilizing the bright-dark soliton conversion control was utilized to secure the optical checksum creation process. The add/drop filter was utilized as an essential device in the proposed system. The results proved that the proposed design could achieve optical checksum in wavelength domain for real time error detection. This method could also quickly create and check the accuracy of information using optical processes. The wavelength of the multi tunnels must be within 50% of the center wavelength of the input signal system to maintain data integrity for optical communication.

Optical asymmetric key cryptography in RoFSO for high security using ring resonator system

A new method for highly secured wireless transmission was proposed as optical asymmetric key cryptography in RoFSO. The optical equipment used for handling high security communication was a PANDA ring resonator and an add/drop filter. A PANDA ring resonator used the dynamic behavior of bright-bright soliton collision. The outputs of the dynamic states were used to form key suppression and key generation as a communication security application. An add/drop filter was used to recover the optical key from suppression and generate an optical asymmetric key (key for sending and key for receiving). Simulation results showed that the proposed design achieved optical asymmetric key cryptography in RoFSO. The sender's data was not perceived by an interferer because the ciphertext data signal was covered by a noiselike signal in a frequency domain of tunnel's form like a noiselike signal.

A new optical data transmission technique through a highly secure tunnel using a crypto carrier was investigated. High speed, high-security communication was achieved with an add/drop filter system and PANDA ring resonator optical equipment. The technique employed coding-decoding generated by public and private optical keys in frequency and time domains using a high-security tunnel. This novel technique provided high speed optical communication using light processing without electric control circuits. Restrictions on the operation of various equipment parameters affected the optical data communication signal intensity. The suitable signal ray data intensity was less than 200% of the signal ray intensity used for generating the optical public and private keys. This new technique ran and transmitted encrypted data efficiently to the receiver.

We propose optical private tunnel using the dark-bright soliton conversion control in a modified add/drop optical filter. By using the control arrangement, the obtained outputs of the dynamic states of dark-bright soliton can be used to form the key suppression which can be available for communication security application, where finally, the key recovery can be obtained by controlling the add/drop filter outputs. The optical private tunnel system consists of data sending section, key learning section and peering section that use an add/drop filter which is used to generate the shape of tunnel from the optical keys, and a Mach-Zehnder interferometer is also used for multiplexing and de-multiplexing operations. The simulation results obtained have shown that the proposed system can be achieved, which can be used to form high security communication. © 2013 IEEE.

We propose a novel method of an optical cryptography using the dark-bright soliton conversion control in a modified adddrop optical filter. By using the control arrangement, the obtained outputs of the dynamic states of dark-bright soliton can be used to form the key suppression for communication security application, in which the key recovery can be obtained by controlling the adddrop filter outputs. The optical cryptography consists of an adddrop filter which is used to generate the encryption and decryption keys from the optical keys (LIP signals). A Mach-Zehnder interferometer is used for multiplexing and de-multiplexing operations.

An interesting security technique that uses the dark-bright soliton conversion control within the microring resonator is proposed. The obtained outputs for a dark-bright soliton dynamic state can be controlled and used to form the public key suppression for communication security application. However, a good design should be possible to be fabricated; therefore, by using the parameters based on the practical device parameters, the simulation results obtained have shown that the proposed system can indeed be achieved. The public key suppression and public key recovery can be used in a highly secure communication system and has potential applications in optical cryptography. © 2011 Society of Photo-Optical Instrumentation Engineers (SPIE).
