In this paper, we consider an indoor Visible Light Communication (VLC) system with a placement technique with and without an overlap formed, using four and five Light Emitting Diodes (LED), placements on a room roof. To support the better received signal power, this paper evaluated the performance of LED overlap using the 3-Watt transmit power. We did a computer simulation using the dimension closed communication room $5 times 5times 3 m^{3}$. In this paper, we found that the VLC system with an overlap was better than the one without an overlap. The result showed that the received power could reach the minimum Bit Error Rate (BER) threshold $leq 10^{-3}$ around −18 dBm for VLC system without an overlap and −20 dBm for VLC system with an overlap. From the simulation, it obtained that communication link coverage with an overlap was about 25 m2.
在本文中，我们考虑了一个室内可见光通信(VLC)系统，该系统使用四个和五个发光二极管(LED)，放置在房间屋顶上，具有或不具有重叠形成的放置技术。为了支持更好的接收信号功率，本文使用3瓦的发射功率来评估LED重叠的性能。我们做了一个计算机模拟使用维度封闭通信室$5 times 5times 3 m^{3}$。在本文中，我们发现有重叠的VLC系统优于没有重叠的VLC系统。结果表明，无重叠VLC系统的接收功率可达到最小误码率(BER)阈值$leq 10^{-3}$，约为−18 dBm，有重叠VLC系统的接收功率可达到−20 dBm。仿真结果表明，有重叠的通信链路覆盖面积约为25 m2。

It is estimated that the annual internet network traffic will exceed the threshold of 3.3 zettabytes by 2021. However, internet architecture is currently inefficient to support the distribution of information-sharing content. Thus, a new internet architecture is designed, namely Named Data Network. Named Data Network (NDN) can store data that has been accessed by consumers in the content store so that when the data is requested by other consumers, it will be fast in distributing data. Nonetheless, it is not possible to store all the content in the content store. Optimization should be made, the existing optimization technique based on the replacement algorithm is Least Recent Used (LRU). However, LRU has a weakness, which only uses the latest reference time and cannot distinguish between frequent or rare objects that are being accessed. Previous research has been conducted on modified-LRU but only on fixed networks, while currently the majority of users use mobile networks, and the condition of mobile networks is very different from the condition of fixed networks. In this research, scenario 5 testing was carried out relating to packet ratio, delay, and packet drop on mobile networks. Modified-LRU show great improvement by the performance of the Hit ratio, 3.6% greater than the LRU, reducing delay by 19.67%, and packet drop by 94% better than LRU.
据估计，到2021年，每年的互联网网络流量将超过3.3 zb的阈值。然而，目前的互联网架构在支持信息共享内容的分发方面效率低下。因此，设计了一种新的互联网架构，即数据网络。命名数据网络(Named Data Network, NDN)可以将消费者访问过的数据存储在内容存储库中，这样当其他消费者请求该数据时，可以快速分发数据。然而，不可能将所有内容存储在内容存储库中。现有的基于置换算法的优化技术是Least recently Used (LRU)。然而，LRU有一个缺点，它只使用最近的引用时间，不能区分频繁访问的对象和罕见访问的对象。以往对改进型lru的研究都是在固定网络上进行的，而目前大多数用户使用的是移动网络，移动网络的情况与固定网络的情况有很大的不同。在本研究中，对移动网络的分组比率、延迟和丢包进行了场景5测试。改进后的LRU在命中率上比LRU提高了3.6%，时延降低了19.67%，丢包率比LRU降低了94%。

The Named Data Network (NDN) has been proposed as a content-based network that will be replace IP networks because the data communication mechanism is more efficient in large network environments. The problem of traffic load on this IP network has actually been tried to be solved with Content Distribution Network (CDN). However, because CDN is a network that is still based on IP, each request will be addressed to a particular server address. In addition, consumer that always moving causes CDN to not be able to overcome dynamic content changes, while consumer demand will often change direction. NDN shift the host-centric, as in IP network, become content-centric. One important component in NDN is the content storage used for data caching. Because content store has limited capacity, it's important to find a caching strategy to improve the performance of NDN networks. In the previous study, the CAPIC caching technique (Caching based on Popularity and Class ) has been proposed which determines treatment for each service class, but the research is only limited to the fixed network. Meanwhile, user with mobility characteristic will become the majority in the network. The character of the mobile network is very different from the fixed network. Routers that have previously stored the data in the content store cannot always be used, because these routers sometimes can be out of network coverage. In this research, the previous CAPIC that only work in the fixed environment is modified to be able to used in the mobile network. This research is conduct to analyze the CAPIC performance in the mobile environment for various conditions. The test results showed CAPIC provided a greater network cache hit ratio than the sharing caching scheme of around 3%, with the first service class performance reaching a maximum 10% compare to sharing scheme. CAPIC also provides a better path stretch for content service classes with a smaller request rate.
命名数据网络(Named Data Network, NDN)是一种基于内容的网络，由于其数据通信机制在大型网络环境中更为高效，因此被提出将取代IP网络。内容分发网络(Content Distribution network, CDN)实际上已经尝试解决这个IP网络的流量负载问题。但是，由于CDN是一个仍然基于IP的网络，因此每个请求将被定位到特定的服务器地址。此外，消费者的不断变化导致CDN无法克服内容的动态变化，而消费者的需求也会经常改变方向。NDN将像IP网络那样以主机为中心转变为以内容为中心。NDN中的一个重要组件是用于数据缓存的内容存储。由于内容存储的容量有限，因此找到一种缓存策略来提高NDN网络的性能非常重要。在以往的研究中，已经提出了CAPIC缓存技术(caching based on Popularity and Class)来确定每个服务类别的处理方式，但研究仅限于固定网络。同时，具有移动性特征的用户将成为网络中的主体。移动网络的特点与固定网络有很大的不同。不能总是使用以前在内容存储中存储数据的路由器，因为这些路由器有时可能不在网络覆盖范围内。在本研究中，对以往只能在固定环境下工作的CAPIC进行了改进，使其能够在移动网络中使用。本研究是为了分析CAPIC在不同条件下在移动环境下的性能。测试结果表明，CAPIC提供了比共享缓存方案更高的网络缓存命中率，约为3%，与共享方案相比，第一个服务类性能最高达到10%。CAPIC还为具有较小请求率的内容服务类提供了更好的路径扩展。

Cholesterol is the most important component of cell membranes that contain fat with most of it being produced in the liver and other parts of food. In general, cholesterol can be known through blood samples carried out in the laboratory. But scientifically, cholesterol can be determined through cholesterol in the iris or called Arcus Senilis. The iris part of a person is very unique so that the patterns and structures are different so that it becomes a feature of identification on someone. Cholesterol can be determined through the thickness of the white value of the cholesterol ring so that it can produce training characteristic values. Linear regression analysis was used to obtain linear regression modeling and then from the results of the linear regression modeling that will be used to determine the value of cholesterol levels. This paper designed an Android-based application for measuring cholesterol levels from eye images. The extraction method used is Gray-Level Co-Occurrence Matrix and calculation of cholesterol levels using Linear Regression. In this research, the process of taking eye images through a smartphone camera and cholesterol consisted to the several classes including Normal Cholesterol, Risk Cholesterol, and High Cholesterol.

The fifth generation (5G) network introduce D2D communications on cellular network. On D2D system, the device can communicate each other directly without using the eNB, with limited range. This D2D network can be superimposed on LTE cellular network and will use same resources with the existing cellular users. The interference will happen between D2D users and the existing cellular users. To maintain the system performances, the resources allocation process become the important aspect, because of the interference among users. This work proposed joint-greedy algorithm, a greedy based allocation algorithm to assign the resources to D2D users for communications process. Join-greedy algorithm consists of two phase of sorting to find the best resource for each D2D users. The first sorting process is to find the best resource for each D2D user, and the second sorting process is to find the best solution from first process result. From the simulation process, the proposed algorithm can improve the spectral efficiency up to 0.309 bps/Hz, and improve the energy efficiency by 12.67 kbps/Watt. The proposed algorithm also can maintain the fairness among D2D pair. Join greedy algorithm has the average fairness index 79.05%. This prove that the proposed algorithm has better system performances compared with the other algorithm.

In accordance with the scenario of ITU-R,IMT-2020 or fifth generation (5G) will have 3 scenarios, one of which is Enhanced Mobile Broadband (eMBB). Multi antenna by applying massive MIMO is used on eMBB. Frequency candidates used in the fifth generation (5G) are sub-6 GHz and sub-28 GHz frequencies. This paper focuses on simulating massive MIMO antenna designs that work at 3.5 GHz and 26 GHz frequencies. The antenna is arranged by rectangular patch in the form of an array with 12 patches for the 3.5 GHz frequency and 96 patches for the 26 GHz frequency, so the number of patches on the antenna is 108 patches. The designed antenna will be used as an indoor transmitter antenna. The antenna uses a proximity coupled feed with connectors and dielectric constants 2.2. The designed antenna gets s-parameter result of less than −10.8199 dB, a gain greater than 7.3 dB, and a mutual coupling of less than −32,6201 dB.

This paper is concerning on developing an interactive wearable flex sensor or data glove to encourage patient during rehabilitation. The data glove main focus is to accurately record and monitor all the data required to produce a comprehensive analysis of the patient's bending fingers progress. This project implements the use of games to introduce excitement in rehabilitation process and Arduino Leonardo for its microcontroller. The Arduino Leonardo comes with a built-in library for keyboard strokes, which eliminates the use of external programs. For testing process, a simulation setup of a patient using the glove was carried out. A Data Acquisition excel was built up to record all relevant data so that it can be further studied. Among the parameters that could be measured are the resistance, voltage produced when forced is applied and the bending angle of each finger. For each of the mentioned parameters, the values were monitored and the overall bending finger's performance of a patient was analysed on a daily or weekly basis.

In this paper, we proposed random resource allocation using water filling for Light Fidelity (LiFi) system, namely Water-Filling Random Resource Allocation (W-FRRA). This paper assumes that the room has several things that can be reflected or absorbed the light from LED bulb and produce blocking probability. We consider that users always move and change, randomly in a room. We use 4x4x3 m for room dimension and power bias 1 W to transmit power for the first time. Power control is used to organise signal to noise ratio (SNR) for equality data rates in any user locations. Our simulation shows that after employee W-FRRA, all of users has similarity data rates around 90Mbps for any propagations distance. After equality data rates are achieved using power allocation, we concentrate for limited time-slot resource, unpredictable packet edge and consider to using Non-Orthogonal Multiple Access (NOMA) for increasing the throughput of LiFi. To prove that our proposed method has improve, we compare random packets transmission such as Slotted ALOHA (SA) and Contention resolution diversity slotted ALOHA (CRDSA). We validate the results using packet loss rate and throughput performances based on computer simulation. We found that W-FRRA has highest performance among SA and CRDSA with most number of user can be served. In addition, the throughput performance of W-FRRA has higher around 10% and 30% than CRDSA and SA, respectively. We also prove that our proposed has fairness system and already employee NOMA to serve users without collision for every location on LiFi system.
