Energy efficiency is the main concern of the 21st century. The smartphone could be a trendy battery operated device and also the experience of the smartphone usage is entirely counting on the battery life. The state of the Smartphone can be Screen_OFF and Screen_ON. Majority of the time spent by the user on the phone is in screen off mode however 30% to 40% of the battery power consumption in this state through Always_On Apps. These apps send tiny burst to their server for various functions at a specific interval of time and keep RRC state busy. This paper proposes an energy-efficient algorithm for high-speed packet data transfer on a Smartphone called PSEO (PS Energy Optimization). It schedules data communication throughout the screen off state based on the radio signal quality. PSEO regulate Data_ON and Data_OFF period while not affecting the user convenience based on the independent value of RSRQ. The proposed research saves the energy up to 28.88%, 78.60% and 16.20% on average of total network energy, Screen_Off energy, and overall smartphone energy respectively

AbstractAlthough photonics presents the fastest and most energy-efficient method of data transfer, magnetism still offers the cheapest and most natural way to store data. The ultrafast and energy-efficient optical control of magnetism is presently a missing technological link that prevents us from reaching the next evolution in information processing. The discovery of all-optical magnetization reversal in GdFeCo with the help of 100 fs laser pulses has further aroused intense interest in this compelling problem. Although the applicability of this approach to high-speed data processing depends vitally on the maximum repetition rate of the switching, the latter remains virtually unknown. Here we experimentally unveil the ultimate frequency of repetitive all-optical magnetization reversal through time-resolved studies of the dual-shot magnetization dynamics in Gd27Fe63.87Co9.13. Varying the intensities of the shots and the shot-to-shot separation, we reveal the conditions for ultrafast writing and the fastest possible restoration of magnetic bits. It is shown that although magnetic writing launched by the first shot is completed after 100 ps, a reliable rewriting of the bit by the second shot requires separating the shots by at least 300 ps. Using two shots partially overlapping in space and minimally separated by 300 ps, we demonstrate an approach for GHz magnetic writing that can be scaled down to sizes below the diffraction limit.

Test Methodology

High-speed transceivers are receiving great interest due to the demand for huge data traffic and information storage capacities in the Big Data era. Recently, 100 Gigabit Ethernet (100GbE) has become an IEEE standardized data communication protocol. The 100G quad small form-factor pluggable (QSFP) transceiver is one of the key technological enablers in the high-speed optical networks. In this paper, we study the reliability current dependence for the four-lambda QSFP (4x25G) EML devices that are employed in the 100G QSFP transceivers. In order to meet the energy-efficient and environmental requirements, we develop a swift reliability test methodology that can provide fast, accurate reliability assessment to ensure robust long-term field performance. We discuss the acceleration factor and extrapolation for the energy-efficient reliability test.

In this paper, research on a high speed arc image sampling and processing system based on DSP has been done. A RS-422A interface has been used to sample high speed image, A TMS320C40 high speed DSP and high frame rate CCD are used as the sensor. The optical image can be converted into digital image in this image sampling and processing system efficiently, with the high speed DSP and the high speed memories, to improve the data transfer speed and receive the image data correctly, DMA data communication technology is adopted. The test result shows that this system is very effective for arc research.

Traditionally, Wireless sensor networks (WSN) are powered by battery. Power diminish aggressively in various operations like data communication, aggregation and data compression so due to these constraints Multi hop routing becomes very promising solutions for high end applications of WSN such as defence area surveillance, monitoring of sensitive environmental conditions, also in precision agriculture, pervasive computing etc. In this paper we proposed that classic Multi Level Leach (ML-Leach) protocol can be further refined to achieve optimum utilization of energy by performing re-grouping at various levels in network considering uniform distribution of node.

Secured Data

The growth of high speed computer networks and that of the Internet, in particular, has increased the ease of Information Communication. Ironically, the cause for the development is also of the apprehension - use of digital formatted data. In comparison with Analog media, Digital media offers several distinct advantages such as high quality, easy editing, high fidelity copying, compression etc. But this type advancement in the field of data communication in other sense has hiked the fear of getting the data snooped at the time of sending it from the sender to the receiver. So, Information Security is becoming an inseparable part of Data Communication. In order to address this Information Security, Steganography plays an important role. Steganography is the art and science of writing hidden messages in such a way that no one apart from the sender and intended recipient even realizes there is a hidden message. In the current internet community, secure data transfer is limited due to its attack made on data communication. So more robust methods are chosen so that they ensure secured data transfer. One of the solutions which came to the rescue is the audio Steganography. But existing audio steganographic systems have poor interface, very low level implementation, difficult to understand and valid only for certain audio formats with restricted message size. Enhanced Audio Steganography (EAS) is one proposed system which is based on audio Steganography and cryptography & watermarking, ensures secure data transfer between the source and destination.

Lzw Algorithm

<p>Now a days mobile ad hoc networks MANETs play a vital role in tremendous communication applications. This networks require infrastructure less module in non- centralized application’s area. Low battery power is of great concern to sustain for a long time, thus researchers try to assist in this critical maintenance point. This work proposed an enhanced version of well-known compression technique LZW to reduce data communication and maintain battery life. Compressed-LZW is a technique to code data stream into further compact form by merging successive redundant compressed code, and achieved by padding the code stream with the displacement of the next similar code. Compressed-LZW outperform its successor in saving consumed energy as expressed in the implementation and results by generating less output codes.</p>
