The following document explores the viability of the usage of consumer-grade, ARM-based single board computers as a power saving alternative to the traditional monolithic x64-full-server based approach.By taking advantage of several capabilities provided by such devices, such as low cost, low power consumption and low on-time, the authors finally propose a scalable, energy-efficient, ARM-based cloud infrastructure.To that end, we start analyzing the current offerings in terms of capabilities, net cost, processing power and power consumption, comparing them with the relevant server-oriented offerings.We subsequently explore the adequacy of several metrics to model on-budget raw data processing, considering full-system wattage under nominal usage conditions.The low initial investment and long-term affordability of this approach results in quite a relevant case of application to Edge Cloud computing scenarios.

Transceiver Module

The aim of this research is to develop a low power, low cost and energy efficient transceiver model which is integrated with programmable microcontroller and ZigBee transponder. A combination of programmable microcontroller with ZigBee transponder is used to control the transceiver module with computer commands. It has b een simulated for transmitting and receiving the communication signals from any movable device with more efficiently and use low power consumption. ZigBee Transponder is preferable as compared to radio frequency identification (RFID) due to IEEE 802.15.4 standard that promises stable data transmission with low power consumption device and having higher network flexibility. PIC 16F877A programmable microcontroller with coding in Mikro C software is simulated and used with computer control instructions. Series of experiments has been conducted to ensure the stability and low power consumption of this model.

Network Localization

Wireless sensor network contains very large number of tiny sensors; some nodes with known position are recognized as guide nodes. Other nodes with unknown position are localized by guide nodes. This article uses the combination of fixed and mobile guide nodes in wireless network localization. So nearly 20% of nodes are fixed guide nodes and three nodes are intended as mobile guide nodes. To evaluate the proficiency, the proposed algorithm has been successfully studied and verified through simulation. Low cost, high accuracy, and low power consumption of nodes and complete coverage are the benefits of this approach and long term in localization is the disadvantage of this method.

Data Process

In order to process and analyze the signal of frequency modulated continuous wave (FMCW) radar, a radar semi-physical simulation(RSPS) system based on STM32F103VE6 chip is designed in this paper. By designing the hardware and software of system, the RSPS system can process the radar signal, detect the target, verify the data process algorithm and display the result on TFT-LCD screen. In addition, the collected data can be uploaded to PC by RS-232 interfaces which improves the reliability, stability and practicability of system. The waveform and spectrum maps are utilized to show the feasibility of RSPS system in analysing FMCW radar signal. Experimental results show that this system has many advantages, such as multifunction, low power consumption and low cost.

Discontinuous Reception

With the rapid development of emerging applications and data transmission rate in LTE (Long Term Evolution) system, terminal power consumption is becoming seriously. In LTE, the discontinuous reception (DRX) mechanism was taken as an important method of saving energy of terminal. Through operations of all sorts of timers, a detailed analysis of the principle of DRX is introduced in this paper. And based on this, adjustable DRX long cycle is proposed. On the basis of the DRX semi-Markov process and ETSI data model, formulas of power saving factor and wake-up delay for adjustable LTE DRX are derived. Then from the comparisons of fixed frame DRX cycle and adjustable DRX cycle in terms of power saving and wake-up delay, we know that this optimizing mechanism has obvious improvement in the reduction of terminal power consumption.
