Design and Implementation of Enhanced Security Model for Wireless Sensor Network on ARM Processor

Abstract

Due to the radio range of the network, suspicious transmission, unattended nature, and easier access, Wireless Sensor Networks are vulnerable to malicious users and physical attacks. Hence security is a must in these cases. A workable solution to these problems might be to create a WSN for a secure temperature sensing system. Sensors gather temperature measurements, which are then communicated to an advanced RISC microprocessor (ARM) using Wireless Fidelity (Wi-Fi) technology, which has been proven to transfer data accurately and reliably. The data is then stored in memory, controlled by the microprocessor. An ARM 9-based Samsung S3C2440 Controller running on the Linux operating system is used to achieve the functionality. The security system is incorporated using the host MCUs, and the temperature values are converted to digital form using the ARM processor’s ADC (S3C2440). The processor is connected to the console terminal through UART, which regularly sends data to the system. Security data is monitored and transferred to other Wi-Fi-equipped devices through a USB-based Wi-Fi module. The temperature readings are continuously monitored via this wireless sensor network. We perform the validation of our study through MATLAB simulations. We measure the sensor nodes’ total energy dissipated, throughput, and lifetime through MATLAB simulations. Over all in this research, we develop improved security in WSN system with application in ARM controller-based secured temperature monitoring system. This paper paves a direction toward further research in physical security in Wireless Sensor Networks.
