Improved QoS in Internet of Things (IoTs) through Short Messages Encryption Scheme for Wireless Sensor Communication

Global interest in Internet of Things (IoTs) can be accorded to the provisioning of Wireless Sensors Communication (WSC). Sensor data cannot be standardized due to diverse nature of measurements. However, the sensor's data needs to be converted into standard size for compatibility with encryption schemes. Therefore, IoTs face various processing and communication overhead issues for acceptable Quality of Service (QoS) in WSC. We proposed a communication model of the Short Messages Encryption Scheme (SMES) Model with the least additional padding in plain text. We performed a comparative analysis of various existing encryption modes and highlighted the limitations concerning compatibility with SMES. Our communication model utilizes Time of Day (TOD) based loose synchronization intervals in combination with Cipher Feed-Back (CFB) mode of AES encryption. Our evaluation of the proposed scheme shows least processing requirements and overheads in comparison with various other encryption modes. We concluded this paper by deliberating possible future research directions in SMES for IoTs.
