An upcoming application scenario is the surveying and exploration of hardly permeable and hardly accessible underground environments such as those of oil-sand mining areas. This scenario requires ten-thousands of millimeter-sized sensor motes (outer diameter less than 5mm) to examine the resource wealth. Within this scope, a correspondingly large amount of extremely resource constrained sensors motes need to have the possibility to sense their environment and interact with each other. In order to enable such application cases, significant energy savings are necessary. An interesting and promising approach is to shorten the sensors' DS-CDMA code sequences and, thereby, reduce the communication related energy costs. In this work, we investigate the resulting downsides of this approach on the range-based localization. As the code shortening leads to the problem of nonunique transmitter identification and consequently non-relatable pairwise distance measurements, the localization of the sensors by typical means is prevented in the first place. This is because multiple sensor motes will concurrently use the same transmit-codes. In this regard, we propose an approach which enables the joint localization and ambiguity resolution and reduces the complexity compared to sequential approaches where at fist the transmit-ambiguities are resolved and a localization with typical methods is performed subsequently.","PeriodicalId":177862,"journal":{"name":"2016 IEEE International Conference on Wireless for Space and Extreme Environments (WiSEE)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127621862","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 existing VLC multiple-input multiple-output (MIMO) system, light emitting diodes (LEDs) vertical MIMO (LVM) model is commonly used. However, in LVM model, illuminance distribution is not uniform enough for office and the optical channel is highly correlated, which degrade the system performance, especially in cases with small emitter separation. In this paper, LEDs inclined MIMO (LIM) model is proposed and the performance comparison of LIM and LVM model assuming line-of-sight (LOS) channel characteristics is presented. Theoretical analysis and simulation results show that LIM model outperforms LVM model in many respects. Firstly, LIM model provides more uniform office illuminance distribution than LVM model. In addition, LIM model with spatial modulation (SM) or spatial multiplexing (SMP) can achieve better bit error ratio (BER) performance when the receiver is in the center, especially with higher signal-to-noise ratio (SNR), because the inclined LEDs can reduce the MIMO channel correlation, which compensates the loss of received power. Besides, when the receiver is on the edge, LIM model with RC, SMP or SM all performs better than LVM model since more power is received and the channel correlation is lower. Furthermore, LIM model outperforms LVM model when considering receiver mobility since LIM model can provide a larger reliable communication area on the receiver plane.","PeriodicalId":177862,"journal":{"name":"2016 IEEE International Conference on Wireless for Space and Extreme Environments (WiSEE)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114136186","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}

The algorithms are set-membership normalized least mean squares (SM-NLMS), SM affine projection (SM-AP) and SM recursive least squares (SM-RLS, also known as BEACON). The lifetime of a wireless sensor network (WSN) is often governed by its power consumption. We show how the previous works for energy prediction, channel estimation, localization and data replication in WSNs can be improved in both accuracy and energy conservation by employing these algorithms. We derive two simplified versions of the SM-AP and BEACON algorithms to further minimize the computational load. The probable drawbacks of the algorithms and the alternative solutions are also investigated. To exhibit the improvements and compare the algorithms, computer simulations are conducted for different scenarios. The purpose is to show that many signal processing algorithms for WSNs can be replaced by one general low complexity algorithm which can perform different tasks by minor parameter adjustments.","PeriodicalId":177862,"journal":{"name":"2016 IEEE International Conference on Wireless for Space and Extreme Environments (WiSEE)","volume":"142 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121711066","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}

It is built on the idea of systematically integrating and interfacing Phased-Array Antenna manifolds to retrieve various sensor information. This approach essentially overcomes the inflexibility of employing passive stand-alone single-aperture phased-array sensor as its performance degrades from systems eclipse due to its scan limit. It is a form of concerted RF sensors, designed to provide extended coverage i.e. wide field of view to compensate for the performance loss suffered from using the passive singly-aperture phased-array RF sensors. The design for these sensors is flexible that they can be reconfigured easily for broad range of RF applications. In addition, these sensors can be integrated on various moving and or stationary platforms with state of the art computing capability coupled with interface connectivity to improve the survivability and reliability of the RF sensors. These systems are especially adaptable to mobile structures such as Robotics and the like for modern RF radar, communication and remote sensing operating at extreme weather condition.","PeriodicalId":177862,"journal":{"name":"2016 IEEE International Conference on Wireless for Space and Extreme Environments (WiSEE)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125283706","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}
