Abstract: As a massive number of devices are becoming part of the Internet, it is highly difficult to organize IoT devices as a system to provide desired services in our lives. It is difficult because the IoT devices are heterogeneous, and the situation often changes overtime which requires the complicated reconfigurations of IoT systems. In this paper, we propose multiagent-based autonomic service organization scheme for IoT systems, which provides IoT devices with the functionality of task-oriented and resilient service provisioning in IoT systems by its capability of agent-based IoT device organization/re-organization. As a proof of concept, we have implemented logistics application using simplified robots using the proposed scheme and conducted logistics experiments.

Abstract: In this paper, a 7-level Diode Clamped Multilevel Inverter (DCMLI) is simulated with three different carrier PWM techniques. Here, Carrier based Sinusoidal Pulse Width Modulation (SPWM), Third Harmonic Injected Pulse Width Modulation (THIPWM) and Modified Carrier-Based Space Vector Pulse Width Modulation (SVPWM) are used as modulation strategies. These modulation strategies include Phase Disposition technique (PD), Phase Opposition Disposition technique (POD), and Alternate Phase Opposition Disposition technique (APOD). In all the modulation strategies triangular carrier and trapezoidal triangular carrier signals are compared with reference signal and control pulses are generated. The detailed analysis of the results has been presented and studied in terms of fundamental component of output voltage and THD.
