R. V. Arvind, Raj, R. R., Raj, R. R., and Prakash, N. K., “Industrial automation using wireless sensor networks”, Indian Journal of Science and Technology, vol. 9, 2016.[Abstract]


Background/Objectives: The advent of Wireless Sensor Networks (WSNs) have revolutionized the field of automation in many ways. This paper presents the implementation of one such WSN useful for industrial applications. Methods/Statistical Analysis: The establishment of the WSN cluster using low cost MSP430 processor and RF transceivers is explained. This network could be easily modified to suit the needs of a particular process in an industry. Findings: A basic hardware system comprising of a cluster having five nodes is tested with real time control signals. Such a network was found to be reliable, low cost and low power consuming. This cluster can be duplicated and such clusters can be integrated with the use of gateways to form a large network to monitor and control the various processes in an industry simultaneously. In the consumer end, these networks will be more user friendly and available at low cost. Applications/Improvements: The WSN clusters can be used for automation of various industries with the possibility of easy modification or expansion in the future. More »»

R. R. Raj and Shanmughasundaram, R., “Simulation of safety critical applications for automotive using multicore scheduling”, in 2015 International Conference on Control Instrumentation Communication and Computational Technologies, ICCICCT 2015, 2015, pp. 12-16.[Abstract]


Technology development has paved the way for enhancement of safety features in a car which has become an important buying factor for customers. Such enhancement demands more computing power. The Electronic Control Units with multicore architecture can be a solution. This offers parallelism which improves the response time of the system. In this paper, Electronic Stability Control and Antilock Braking Systems are the two safety critical applications considered for improving the response time through multicore implementation. Data dependencies may occur between the tasks of different cores. One way to overcome the dependencies is through the shared memory which requires inter-process communication protocols such as mail box and queues. In this paper, the mailbox is used for storing the common parameter between the two applications which is the value of brake torque for each wheel. The task set is developed for these applications and scheduled using dock-driven scheduling algorithm. The TORCHE toolbox in Matlab is used for simulating the task set in single core and multicore architectures of ECU. The simulation results indicate the significant improvement in temporal characteristics of task execution in multicore when compared with the single core implementation. More »»
