Patient health parameters are monitored by wireless sensor network and communicated to the far end through Zigbee interface. Data received at far end is monitored by MATLAB. If the parameters are abnormal it configures the GSM module to send SMS on doctor mobile phone. System implemented in this paper is made for such patients who are not in the critical state but they need to be monitored continuously. When the critical condition occurs, system will originate an alarming message and send it to the doctor. It is fast, less costly and monitors patient remotely from their homes.","PeriodicalId":339960,"journal":{"name":"2017 2nd Workshop on Recent Trends in Telecommunications Research (RTTR)","volume":"202 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116173064","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 impact of advance modulation technique based on the bit error rate (BER) performance have been investigated. The effect of Multiple access interference (MAI) and bit noise degrades the performance of the OCDMA/WDM system. Advanced modulation technique DPSK and MDW code sequence have been proposed to reduce MAI and bit noise. Here, we have compared AND subtraction detection and complementary subtraction detection techniques at data bit rate 2.5 Gbps. The simulation results elucidate that the complementary subtraction detection technique performance is better than AND subtraction detection technique where referred BERs 2.19×10-09 and 3.12×10-07 respectively. According to the simulation results, this hybrid system can be considered as a good candidature for GPON Application.","PeriodicalId":339960,"journal":{"name":"2017 2nd Workshop on Recent Trends in Telecommunications Research (RTTR)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126303667","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 paper also investigates a new method to increase the accuracy of the ABER for a wide range of applications work under low or high SNR levels. Moreover, the ABER is used to calculate the EBER, which is more complex than the ABER. Thus, the BER of BAF-MR networks can be evaluated under low and high SNR levels using either ABER or EBER.

In UWSN small sensor nodes with limited battery and limited memory are deployed in underwater environment. Due to multiple differences from terrestrial Wireless Sensor Networks (WSN), radio waves cannot be used in underwater communication. Acoustic channels are used for communication in sea water. Acoustic channels has many communication constraints like low bandwidth, high end to end delay and high path loss. Therefore energy efficient communication in underwater networks has became uttermost need of wireless sensor technology. This paper has compared the three main Location based Routing protocols in UWSN. Such as Vector Based Forwarding(VBF), Hop by Hop- Vector Based Forwarding(HH-VBF) and Focused Beam Routing (FBR) has been compared using MATLAB simulation tool. These protocols has been compared on the basis of data delivery ratio, number of alive nodes, end to end delay and total consumed energy.","PeriodicalId":339960,"journal":{"name":"2017 2nd Workshop on Recent Trends in Telecommunications Research (RTTR)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125449755","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 traditional approach to address this issue is to formulate it into an optimization problem with QoS and server temperature constraints. In this paper, we develop a Temperature-Aware Resource Management (TARM) algorithm using Lyapunov Optimization theory. One advantage of our approach is that we use a “soft” (average) server temperature constraint instead of a “hard” (instant) one without impairing system reliability. We use a real world data center workload trace to evaluate our proposed algorithm, and simulation results show that our approach can at least save 6% of the overall energy consumption.","PeriodicalId":339960,"journal":{"name":"2017 2nd Workshop on Recent Trends in Telecommunications Research (RTTR)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117148039","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}

To enhance the scalability and reliability of publish/subscribe (pub/sub) systems implemented on a large-scale in WSNs, dedicated broker devices with large storage and computation capacities can be replaced with virtual brokers (VBs), each formed by multiple co-located sensor nodes that shared resources to collaboratively perform the role of a conventional broker. As communication is a major consumer of energy, which is a scarce resource in WSNs, how the WSN is structured in terms of the number of partitions and the size of VB can impact the energy consumption of the network. In this paper, we propose a novel approach to optimal network structuring of large-scale WSN with virtual brokers for pub/sub communication. Underlying the approach is an analytical model which determines the optimal number of partitions and VB size that jointly minimize the total communication overhead of the WSN.","PeriodicalId":339960,"journal":{"name":"2017 2nd Workshop on Recent Trends in Telecommunications Research (RTTR)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123024653","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 paper, a complete VLC software defined radio (SDR) transceiver is implemented on National Instrument (NI) cDAQ modules programmed in LabVIEW/MATLAB. The transceiver design mainly consists of VLC transmitter, receiver and interfacing of cDAQ modules. The major blocks of VLC transmitter comprise Optical Code Division Multiple Access (OCDMA) to improve the signal quality. The novelty in the designed prototype is that it is capable of compensating errors over a distance of 1 meter in a brightly lit room. Over and above physical system, simulation programs are also developed to investigate the impact of line-ofsight (LOS) VLC channel. In order to investigate VLC channel, Bit-Error-Rate (BER) performance is carried out to compare the proposed system with traditional VLC system.","PeriodicalId":339960,"journal":{"name":"2017 2nd Workshop on Recent Trends in Telecommunications Research (RTTR)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123352541","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}

Currently, the user association techniques are under the influence of single slope path loss model. The densification of networks and irregular cell patterns have increased the variations in both the link distances and interferences; making single slope path loss models less accurate. In this paper, we consider the downlink of a HetNet with picocells overlaid on a macrocell and propose a framework for user association with dual slope path loss model. Simulation results show that the dual slope model improves the system performance compared to the standard single slope model by offloading more traffic from macro-tier to pico-tier; the effect being more significant at higher edge user density. Furthermore, the user association is highly dependent on the path loss exponents in a dual slope model.","PeriodicalId":339960,"journal":{"name":"2017 2nd Workshop on Recent Trends in Telecommunications Research (RTTR)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124042475","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}
