The following report is all about wireless powered communication network (WPCN) is new method where battery of wireless communication devices can be replaced by the help of microwave power transfer (Yang et al. 2015). This particular technology aims to remove the need for manual battery recharging. It merely aims to improve the overall performance in comparison to the conventional battery powered communication-based network. It is merely seen in various kind of aspects like higher throughput, devices of long life, low operating cost value. In most of the cases, the design and future application of WPCN is completely challenged by the help low WPT efficiency is the long distances (Qu et al. 2016). It is known to be complex nature which is needed for joint wireless information and power transfer in the given network.
In the report, we come across the main work on which the two given papers are completely based on. A proper idea has been provided with respect to two different methodologies that are being two of these papers. The overall results of the two papers are compared in details. Both advantages and drawbacks are described in detail in two of paper.
As a result of control battery life of device, there is a need for modification for mobile device based wireless technologies. Due to frequent recharging of battery, there can be huge amount of cost to wireless devices that are in use. In the case of infeasible for critical application like embedded sensors that are in proper structure and medical devices (Kang, Ho and Sun 2015). The whole thing comes into picture as a result of RF-based wireless energy transfer (WET) technology. It mainly aims to provide the best kind of solution that is seen as a result of powering wireless devices along with continuous and stable energy. The whole thing comes into picture by leveraging the radiative properties for wireless communication for electromagnetic wave. At present, wireless receivers can easily harvest energy that is available from RF signal that is radiated by energy transmitter (Bi, Ho and Zhang 2015). RF-based WET aims to enjoy much more advantages like minimum range of operating, minimum production cost and efficient energy multicasting that is needed for analyzing the nature of present EM waves.
The second paper aims to highlight the latest development in wireless power transfer that is needed for creating wireless powered communication networks. In this, devices are being powered over the air by making use of wireless power transmitter needed for communication (Dey et al. 2016). The paper aims to focus on conventional battery powered network where WPNC remove the need for manual battery replacement. WPCN comes up with full control on transfer of power where the transmitted power, waveforms are completely occupied in required frequency. It is completely tunable that is needed for providing much stable supply of energy that is available in various physical condition and equipment for services.
In the last few years, WET technology has gained huge amount of popularity. The current technologies of WET can be easily divided into three sub-categories based on physical mechanism. The categories are inductive coupling, magnetic resonant and lastly EM radiation (Tsonev, Videv and Haas 2015). Among all the available one, the first two types is needed for exploiting the non-reactive one. At present, inductive coupling WET is completely categorized with various application like charging of mobile phones and devices that are implanted. By understanding the far-field properties for EM waves, wireless receivers can easily harvest energy that is remotely available from RF signal. The biggest plus point of RF-based WET is that wireless devices are completely harvested by transmitted for decoding required information available for other devices.
At present, WPT technology is considered to be very much effective one which can transfer energy of ten microwatts power of RF to WD that is from the distance of 10 meters. It is known to be important aspect which is needed for improving the overall magnitude in the range that has future development (Bi, Zeng and Zhang 2016). WPCN is known to be very much suitable for a range of low-power based application in the devices that operate in given milliwatts like WSN and RFID. Both WPT based sensor and RFID tags are completely available in whole of the market. This particular technology will reshape the whole landscape of industries like IoT and M2M communication.
The first paper aims to highlight about WET is mainly applied to various kind of communication devices. It will merely occupy a part of the spectrum which is needed for communication (Popovski et al. 2018). For neglecting any kind of interference to the medium of communication comes up with a simple kind of insufficient methods. It is mainly needed for transmission of energy and required information in orthogonal way. There is a SWIPT design which is completely design for saving the spectrum by proper transmission of information. In the joint form of energy makes use of some kind of waveform (Yaqoob et al.. 2017). An efficient SWIPT mainly requires a rate of energy trade-off that is available for both transmitter and receiver. The complete design is provided for providing balance to the information decoding and performance of energy harvesting.
In the second paper, an overview has been provided with respect to basic operating model where some of the complex WPCN are completely built various kind of nodes (Lu et al.. 2015). The overall performance of WPCN is completely constrained by making use of low efficiency and much short value. It merely comes up limited resource which is need for transmission of energy and information. The paper highlight some of the techniques which are needed for improving the performance of WPCN (Vinel et al. 2016). The paper has subdivided the discussion into four sub-section that is beamforming of energy, communication in joint and scheduling of energy, multi-node communication, and wireless powered communication.
The first paper aims to provide an overview with respect to state of the art for RF-based WET application in wireless communication. There is large number of opportunities and challenges associated with the overall design of wireless-based communication (Chen and Kunz 2016). It is completely studied by analyzing two important aspects that is SWIPT and WPCN. It is expected that the design of wireless communication will improve research communication for various wireless technologies.
In the second paper, we come across both the design and future application of WPCN which is completely challenged by low WPT efficiency over long distance. The whole thing comes into picture as a result of power transfer that is available in the same given network (Yang et al. 2015). The paper aims to provide an overview with respect to the present networking structure and improving techniques needed for building efficient WPNC. There is both new and challenging future research for WPCN.
WPC comes with huge number of issues which requires some important application. The paper aims to highlight various kind of topic with respect to WPC.
Energy and Transfer of Information: As a result of critical power aspects for wireless devices, the upcoming system is considered to mixture of wireless energy and communication network (Qu et al. 2016). In this spectrum, two kinds of network tends to operate on the overlapping spectrum.
Cross-layer design: Till now physical layer techniques focus on optimizing the overall performance for WPC. In real world, MAC aims to play a key role in understanding the overall efficiency of the system.
In the second paper, we come across WPCN which highlights the issues of vital aspect that needs to be considered. In this particular section, an idea is being provided with respect various areas of research topics like extensive, green WPCN, cognitive WPCN (Kang, Ho and Sun 2015). Beamforming energy is a well-known method in WPCN. The upcoming technologies aim to provide full-duplex technology that is needed for providing folded performance.
The above pages help us in concluding the fact that this report is all comparing two papers that are completely based on wireless communication. An idea has been provided with respect to the basic model for WPCN that improves the overall reliability of the network. It is all about making use of techniques that are being introduced for WPCN which is much similar to the conventional wireless communication network. There are large number of techniques are being used for WPCN which is very much similar to the conventional wireless communication network. Apart from this, there is a need for energy transfer that requires much-sophisticated design of system. This particular technology aims to bring huge amount of valuable information which is needed for overcoming the scarcity issues related to wireless communication network. In the coming years, WPNC will be a vital aspect of building block that is needed for future wireless communication system. It is mainly needed for achieving self-sustainable for operation of devices.
