Stagnant weather conditions caused a sharp increase in fatalities and for more than a year almost four people died each day leading an unexpected death toll over 4000 due to the release of 42 tons of toxic Methyl Isocyanate gas. This event is not an isolated incident that affected humans and the environment, as there have been many similar events such as Meuse valley, Belgium, London Smog event etc. Particulate air pollution has been conventionally measured by passing air through a particular filter paper and determining the density of black stain, known as “black smoke method”. Most metropolitan cities are seeing a significant increase in their vehicular registration count and have increased the black exhaust containing CO and other harmful gases along with particulate matter, thus rendering the black smoke method obsolete.","PeriodicalId":91517,"journal":{"name":"International journal of sensor networks and data communications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4172/2090-4886.1000158","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70965718","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 beneficial for human growth and the State’s emerging Gross Domestic Product (GDP). South Asia particularly Pakistan is facing severs challenges of poverty, hunger and malnutrition along with growing population. Under these conditions, horticulture governed with emerging scientific research and developments can play a vital role in order to cope up with such challenges. Tunnel farming is such kind of one development being practiced across the globe to obtain off-season crops with three folds of more production as compared to the traditional way of vegetation. In this regard the concept of Internet of Things (IoT) is a promising approach which finds its expertise in every field of life including agriculture sector. Its application in tunnel farming has been generating ambitious results in the past few years therefore, a sound architecture and model based on latest, robust and reliable technologies can change the fate of agricultural sector in Pakistan. This paper proposed a framework with hardware design which comprises of accurate sensors for data transmission to Cortex based MPU, cloud based data unit and further appropriate actuators to regulate the desired microclimatic conditions inside the tunnel to improve the productivity followed by more revenue. Proposed hardware model provides a cheap, optimal and automatic tunnel farming solution to the middle class farmer, growing off-season crops at the far ends of the country with scarcity of electricity and water resources. Furthermore it presents a reliable user friendly database and a very simple GUI that makes it easy for the farmer to monitor the climatic changes, optimal resource utilization, the production at the far site end and its healthy transportation to the nearest consumer market along with periodic reporting of location and vital microclimatic conditions inside the vehicle. To our knowledge, this is the first proposed hardware model which uses Cortex based microcontroller for Smart Tunnel Farming. By the proposed hardware model, the cost of electricity and water can be reduced by 30 to 40% and an average of 20% increment in the production and supply of targeted crops by automatic adjustment of optimal climatic conditions inside the tunnel and monitoring of crops transportation system.","PeriodicalId":91517,"journal":{"name":"International journal of sensor networks and data communications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4172/2090-4886.1000161","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70966044","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}

Choi","doi":"10.4172/2090-4886.1000159","DOIUrl":"https://doi.org/10.4172/2090-4886.1000159","url":null,"abstract":"Since the adoption of Bluetooth Low Energy (BLE) in the Bluetooth standard in 2010, BLE beacons are emerging as one of the most viable solutions for indoor localization due to its power efficient architecture, short scan duration, low cost chipset, and wide adoption in the devices. The existing indoor positioning systems based on BLE beacons employ the classical fingerprinting (FP) technique where user terminals collect signals from the beacons and do most of localization computations, requiring significant power consumption on user devices. However, constant power consumption on limited battery life of a mobile device can be problematic when it comes to supporting server-oriented tracking applications. To address this issue, we have proposed a new fingerprinting technique called inverse fingerprinting (Inv-FP), which is a server side BLE fingerprint system where most of the positioning computations are done by BLE sniffers and servers, thus minimizing the computation overhead of user devices. However, the absolute positioning schemes such as FP and Inv-FP do not use the current position estimate to determine the next position. This leads to discontiguous, irregular route prediction especially when the positioning accuracy is low, since it does not reflect the continuity of the position change according to the movement of the user. In contrast, a relative positioning scheme such as Pedestrian Dead Reckoning (PDR) determines the current position based on the previous position, reflecting the continuity of the position change but it cannot estimate the current position without the initial position. In this paper, we implement both FP and Inv-FP and evaluate their performance in small and large-scale testbeds. We analyze various characteristics of Inv-FP in comparison with the classical beacon based FP, and demonstrate that Inv-FP can match the performance of FP but with minimal power consumption on user devices. In addition, we propose a new localization algorithm that can combine Inv-FP with PDR. By integrating PDR with Inv-FP, we show that localization error can be reduced by reflecting the advantages of each method.","PeriodicalId":91517,"journal":{"name":"International journal of sensor networks and data communications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4172/2090-4886.1000159","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70965730","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}
