This characteristic, if not taken into account when designing the localization algorithm, may severely hinder its accuracy. Assuming a random transmission capability at each EH sensor, we develop a new approach to derive the expected hop progress (EHP). Exploiting the latter, we propose a localization algorithm that is able to accurately locate the EH sensors owing to a new implementation requiring no additional power consumption. Furthermore, we develop a correction mechanism which complies with the heterogeneous coverage nature of EH sensors to further improve localization accuracy without incurring any additional power cost. Simulation results show that the proposed algorithm, whether applied with or without correction, outperforms in accuracy the most representative WSN localization algorithms in EH powering contexts.","PeriodicalId":339208,"journal":{"name":"2015 IEEE International Conference on Ubiquitous Wireless Broadband (ICUWB)","volume":"917 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123044186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this scenario, the data transmission is based on short packet so as to meet the micro-power budget of autonomous power harvesting. The burst short packet transmission as well as the low duty cycling UWB pulse modulation places a stringent challenge at the UWB receiver for timing acquisition and packet detection. Besides, in a positioning enabled RFID system where variable signal-to-noise ratio (SNR) due to the variable link distance and noise background is unavoidable, conventional packet detection schemes rely on predefined threshold can hardly achieve good performance. In this study, we propose a low complexity method for burst packet detection. It is performed by sensing the preamble signal characteristic instead of the received signal strength, and thus bypassing the necessity of detection threshold. The validity of the proposed approach and its adaptivity to SNR variations is demonstrated by simulation results as well as field test with a UWB software defined radio (SDR) platform.","PeriodicalId":339208,"journal":{"name":"2015 IEEE International Conference on Ubiquitous Wireless Broadband (ICUWB)","volume":"43 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115756264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This set-up replaces the bi-static antenna configuration that is needed for reflection based permittivity estimation. This technique is an advancement of the established Microwave Ellipsometry. The developed measurement technique and setup is called microwave retroreflector ellipsometry (MRE). The experimental validation is carried out with comparison with the well established delay time measurments (DTM) technique. Hence, different dieletric surfaces are examined.

The nonlinear nature of the rectifying process hinders the development of optimized circuits for maximum efficiency. This has provided the incentive for researchers to use a different approach for increasing the efficiency of the rectennas. The approach consists of interconnection of multiple rectified signals at the direct current (DC) level through serial, parallel or cascaded connections in multiple antenna receivers. Successful experiments have already been conducted and shown the superiority of the cascaded combination in terms of both efficiency and output voltage at the receiver side, when there are only two rectennas to be combined. In this paper, we aim to formulate and recast this design problem in analytical form for the general case when there are K rectennas in the energy harvesting system. The superiority of the cascaded technique is validated through analysis and comparison of the three combination techniques in terms of efficiency, produced DC voltage and output DC current.","PeriodicalId":339208,"journal":{"name":"2015 IEEE International Conference on Ubiquitous Wireless Broadband (ICUWB)","volume":"221 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116384134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We consider a single DF relay scenario with orthogonal cooperative protocols and an active jammer during all the transmission phases attacking the relay and destination nodes in the network. In our analysis, we assume that the complex fading channel coefficients are estimated at the relay and destination levels with errors. We derive the error performance and the throughput of the network then we quantify the impact of channel estimation and the jamming power through the derivation of analytical performance expressions. Our simulation results confirm the accuracy of our analytical BER expression and quantify the performance degradation due to channel estimation and jamming signals.

An analog MIMO equalizer, which equalizes the deterministic MIMO channel is involved. Instead of interference suppression, the analog MIMO equalizer aligns the phases of the received signals and enhances the desired signal while it suppresses the undesired ones simultaneously. Although the magnitudes of different signal components of the received signals are preferred to be unique, further studies are applied in our work to investigate the validation of our system design with non-unique magnitudes by using practical on-board antennas. It is shown that the proposed system works well with non-unique magnitudes where undesired remaining interference occurs with limited power in comparison with the desired ones. Furthermore, the proposed design shows a great potential for putting a 1 Tbps wireless data bus into practical systems with moderate transmit power and fairly simple modulation schemes which provide high energy efficiency.","PeriodicalId":339208,"journal":{"name":"2015 IEEE International Conference on Ubiquitous Wireless Broadband (ICUWB)","volume":"27 18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128718921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A cascade of a low-noise amplifier (LNA) and a mixer achieves a voltage gain of 31.4 dB, and a noise figure (NF) of 6.8 dB while consuming 360 μW. A 101 μW voltage-controlled oscillator (VCO) is also demonstrated. Several low-power architectures, including a combination of an LNA with a VCO, are also presented.
