“…TinyOS [63,64] implemented with the programming language nesC, Contiki [65] and FreeRTOS [66], are very famous RTOSes. They all offer preemptive priority-driven task schedulers, so as to develop the IoT applications [67]. However, such RTOSes, even if suitable for battery-operated sensors, do not yet integrate clairvoyant and idling schedulers such as ED-H to accommodate the energy neutrality.…”

Energy harvesting is a green technology that authorizes small electronic devices to be supplied for perpetual operation. It enables wireless sensors to be integrated in applications that previously were not feasible with conventional battery-powered designs. Intermittent computing and scheduling are the two central aspects of designing a Real-Time Energy Harvesting (RTEH) sensor, generally used to monitor a mission critical process. Traditional scheduling algorithms fail to timely execute the hard deadline tasks because they accommodate no fluctuations in power supply and therefore no intermittent computing. A suitable energy-harvesting-aware scheduling algorithm has been proposed so as to achieve a higher schedulability rate. Unlike the classical EDF (Earliest Deadline First) scheduler, the ED-H algorithm is idling and clairvoyant, with an improved performance in terms of the deadline missing ratio. This paper reviews the main advances in dynamic priority scheduling based on EDF for energy-neutral systems.

This paper provides an overview of blockchain technology's security and privacy features, as well as an overview of IoT-based cache memory and single-bit six transistor static random-access memory cell sense amplifier architecture. Each chip's memory is used for recorded as blocks, which are encrypted and used as a blockchain for other memory devices. The architectures comprise of the circuit of write driver, six transistor static random access memory cells, and sense amplifiers such as current differential sense amplifier, charge transfer differential sense amplifier, and voltage latch sense amplifier. Furthermore, different parameters such as the number of transistors, sensing delay, and power consumption have been analyzed for varying resistance values (i.e., R=42.3 and R=42.3K ). Apart from that, power reduction techniques such as dual sleep, forced stack, sleep transistor, and sleep stack are used to optimize power consumption. These power reduction techniques are applied over different blocks of architecture, such as six transistors static random access memory cell and sense amplifier to optimize power consumption of the architecture. The conclusion arises that a single-bit six transistor static random access memory cell with power reduction dual sleep technique voltage latch sense amplifier with power reduction dual sleep technique in architecture consumes 11.65µW of power and has 33 transistors which are lowest from other architectures.INDEX TERMS Circuit of write driver (CWD), sense amplifier (SA), current differential sense amplifier (CDSA), charge transfer differential sense amplifier (CTDSA), voltage latch sense amplifier (VLSA), six transistor static random-access memory (6T-SRAM).

Advances in information and communication technology continue to grow over time. This causes significant changes in social, economic, and political conditions. One company that requires strong network security is PT PLN (Perusahaan Listrik Negara) Persero, which is a leading energy company in Indonesia. In this case, the need to evaluate network security at PT PLN is very important. This evaluation will help identify vulnerabilities and security gaps that exist in PT PLN's network infrastructure. This network security evaluation using the Penetration Testing Execution Standards (PTES) method can provide an overview of the vulnerabilities or weaknesses of the network system at PT PLN UP2D S2JB which has quite a lot of gaps to exploit. This is evidenced by the results of fifteen tests conducted, only two of which failed, namely in the type of attack The Rogue Access Point. The results of Penetration Testing are very necessary and important as feedback for system managers in fixing existing vulnerability gaps.
