This paper presents a fully-integrated µW-level photovoltaic (PV) self-sustaining energy harvesting system proposed for smart nodes of Internet of Things (IOT) networks. A hysteresis regulation is designed to provide a constant 3.3 V output voltage for a host of applications, including powering sensors, signal processors, and wireless transmitters. Due to the stringent power budget in IOT scenarios, the power consumption of the harvesting system is optimized by multiple system and circuit level techniques. Firstly, the hill-climbing MPPT mechanism reuses and processes the information of the hysteresis controller in the time-domain and is free of power hungry analog circuits. Secondly, the typical power-performance tradeoff of the hysteresis controller is solved by a self-triggered one-shot mechanism. Thus, the output regulation achieves high-performance and yet low-power operations. Thirdly, to execute the impedance tuning of MPPT, the capacitor value modulation (CVM) scheme is proposed instead of the conventional frequency modulation scheme, avoiding quiescent power consumption. Utilizing a commercial PV cell of 2.5 cm 2 , the proposed system provides 0-21 µW output power to the IOT smart nodes. Measured results showed that the PV harvesting system achieved both ultra-low power operation capability at 12 µW and a peak self-sustaining efficiency of 86%.

“…MIoT have been discussed in previous studies [4], [9]] but their contribution and integration into research are still in early stages. However there are some applications that came into practice [5], [10], [11]. We have divided such applications as traffic monitoring, environment monitoring, home security monitoring, smart surveillance and e-health monitoring.…”

“…Multimedia communications in real time IoT applications may experience network delay and congestions due to bandwidth constraints and packet loss, which have an adverse impact on the delivered multimedia quality. QoE/QoS aware Multimedia communications in IoTs (MIoT) have been proposed in recent years [4], [5] to address the above issues. However, according to Qualinet QoE is the overall acceptability of an application or service perceived by the end user, and is more user-driven [6].…”

Multimedia communications play a major role in Internet of Things (IoT) applications such as traffic control and management, environmental monitoring, healthcare, surveillance, event recognition and home monitoring and automation. To ensure the quality of multimedia content to be collected, processed and delivered appropriately in such applications, it is necessary to design and develop a quality aware IoT architecture for multimedia IoT applications. Research on Quality of Experience (QoE) in multimedia communications in IoT has gained attention in recent years. However, the concept of IoT is to connect everything in a smart way without human interaction. Therefore, this paper introduces a new concept of Quality of Things (QoT) for multimedia communications in IoT, a new architecture based on the QoT for multimedia communications in IoTs is also proposed together with its challenges and future research directions.

“…The obtained results show that more than 95 percent of energy can be saved by employing TDMA-based scheduling, whereas up to 5 years of battery life can be achieved in the large-scale LTE-based IoT scenario by employing the proposed DRX mechanism. In [8] This paper proposed a new quality-optimized sky camera multimedia information gathering scheme for IoTs based smart grid solar power estimation. In the proposed scheme, the transmission power control and relay node selection strategies were jointly optimized based on multimedia packet distortion reduction.…”
