Open Networking Lab: online practical learning of computer networking

Learning to configure computer networks is a topic requiring a substantial practical component and suggesting a pedagogic approach that foregrounds experiential learning. However, providing appropriate computer networking hardware is expensive for classroom labs, and is not viable for individual distance learners. Simulation offers an alternative basis for practical learning and supports a range of modes, from individual distance learning to in-class blended learning. Sophisticated network simulation packages, such as Cisco’s Packet Tracer, have high fidelity to networking devices and can simulate complex network scenarios. Unfortunately their complex interfaces make it difficult for a novice student to engage productively. The Open Networking Lab (ONL) will provide online resources for students of introductory computer networking. It will take an activity-centred approach, supported with video and screencasts, in preference to lengthy text. Practical activity is based on PT Anywhere, a network simulator that provides students with an easy-to-use, browser-based interface over Cisco’s Packet Tracer. PT Anywhere thus provides fully authentic simulation but, by only revealing a subset of features, supports a carefully scaffolded approach to teaching and learning. We report at an early stage in the development of the ONL. Material is being piloted with students at UK Further Education colleges. Evaluation will include observation, surveys and interviews with students and staff; PT Anywhere also provides learning analytics. A further stage of development will culminate in a badged open course on the Open University’s OpenLearn platform. The ONL will provide vocational learning at scale in educational institutions, employment contexts and for individual learners

Pada era revolusi informasi yang berkembang dengan cepat, teknologi komputasi berbasis internet menjadi sangat dibutuhkan karena kemudahannya . Hal ini menyebabkan ketergantungan bisnis akan Teknologi Infomasi semakin tinggi dan hal ini sejalan dengan ancaman serangan siber yang semakin meningkat. PT. XYZ sebagaiperusahaan di bidang jasa penyedia cloud datacenter yang dapat dikategorikan critical infrastructure. Critical infrastructure memiliki komponen yang didefinisikan sebagai sistem dan aset, baik virtual maupun physical. Komponen kritikal virtual yang berfungsi dalam menjaga keberlangsungan bisnis PT. XYZ adalah Sistem dan Teknologi Informasi, Sehingga diperlukan cyber resiliency yang dapat menjamin ketersediaan (availability) dan integritas (integrity) data dan layanan digital. Selain hal tersebut diatas, untuk menjaga ketersediaan layanan IT diperlukan juga pengadaan environment server yang berbasis virtualisasi pada Data Center (DC). Pengembangan dan peningkatan sistem ini sangat diperlukan m engingat pada saat ini belum tersedianya perangkat server yang ber basis virtualisasi cloud pada Data Center

Healthcare System through Wireless Body Area Networks (WBAN) using Telosb Motes

Due to the increased demand for an effective communication technology in the health care sector, a wireless network is needed that effectively monitors the patient’s vital sign and send reports concurrently to the remote system. This increases the comfort level of monitoring the patients continuously. The main idea of this article work is to build up a WBAN that endlessly monitors human healthiness parameters and reports information to the nearby PC/sinks. The small wearable devices which is memory efficient, energy efficient, less computational complexity are deployed on the patient to be monitored. They self-configure to endlessly monitor critical signs such as heart beat, core temperature etc. The energy efficiency and transmission delay is analyzed by using Cooja simulator. Finally the design is implemented in the Telosb wireless sensor motes

A comprehensive survey of wireless body area networks on PHY, MAC, and network layers solutions

Recent advances in microelectronics and integrated circuits, system-on-chip design, wireless communication and intelligent low-power sensors have allowed the realization of a Wireless Body Area Network (WBAN). A WBAN is a collection of low-power, miniaturized, invasive/non-invasive lightweight wireless sensor nodes that monitor the human body functions and the surrounding environment. In addition, it supports a number of innovative and interesting applications such as ubiquitous healthcare, entertainment, interactive gaming, and military applications. In this paper, the fundamental mechanisms of WBAN including architecture and topology, wireless implant communication, low-power Medium Access Control (MAC) and routing protocols are reviewed. A comprehensive study of the proposed technologies for WBAN at Physical (PHY), MAC, and Network layers is presented and many useful solutions are discussed for each layer. Finally, numerous WBAN applications are highlighted

Implementation of Base Station as An Intermediary Referee Box in the delivery of Wheeled Football Robot Movement Commands

In the contest of Indonesian wheeled robot football or KRSBI wheeled robot which competes with wheeled football robots, there is a referee who controls the course of the match, the referee box. For referee box to provide commands that can set the course of the robot, a base station is required that serves to receive data from the referee box and translated and then sent it to the robot. The use of TCP socket programming is quite successful whereby 17 attempts to send commands from referee box can be accepted all by base station with a success rate of 100%. The use of robot operating system (ROS) to pass data in the form of coordinate points and commands for robots chasing balls or stops was also successfully carried out where from 17 attempts the delivery of orders, it can reach 100% success rate. After that, the measurement of distance analysis against quality of service (QoS) with 3 different distances, and obtained the following results, at a distance of 3 meters obtained an average delay of 44.41 ms, throughput of 767.29 kbps and no missing package, at a distance of 8 meters obtained an average delay of 7.22 ms, an average throughput of 1065.17 kbps and no missing packages, lastly at a distance of 15 meters obtained an average delay of 103.99 ms, an average throughput of 835.51 kbps and there was a missing package of 6.9% on 1 order so that the average lost package was obtained by 0.405%
