IoT Smart Device for e-Learning Content Sharing on Hybrid Cloud Environment
Centralized e-Learning technology has dominated the learning ecosystem that brings a lot of potential usage on media rich learning materials. However, the centralized architecture has their own constraint to support large number of users for accessing large size of learning contents. On the other hand, Content Delivery Network (CDN) solution which relies on distributed architecture provides an alternative solution to eliminate bottleneck access. Although CDN is an effective solution, the implementation of technology is expensive and has less impact for student who lives in limited or non-existence internet access in geographical area. In this paper, we introduce an IoT smart device to provide e-Learning access for content sharing on hybrid cloud environment with distributed peer-to- peer communication solution for data synchronization and updates. The IoT smart device acts as an intermediate device between user and cloud services, and provides content sharing solution without fully depending on the cloud server
Radio frequency identification (RFID) : evaluation of the technology supporting the development of Program Latihan Khidmat Negara (PLKN) participants tracking application
Radio Frequency Identification technology has been adopted into goods tracking, human tracking and identification of valuable items to fulfill the needs of identification. Reliable RFID communication requires good communication protocols as well as decision support protocols. The purpose of this paper is to review the current RFID technology and to explain the anti-collision protocol which is the communication protocol that eliminates the collisions between reader and tag as it will prevent reader from obtaining data from tags. Besides, this paper will also introduce the positioning protocol as a part of decision support protocol which is used to help the system to determine the location of required tag. These protocols are the random back-off anti-collision protocol which uses counter to generate random duration for next transmission to avoid tags from transmitting at the same time, simple positioning protocol and receiving power based triangulation method using Heronpsilas formula for positioning protocol use the concept multi readers to formulate the location of tag. Simulations have been done to illustrate how the protocols work. These protocols may be used in certain low end systems which cater fewer functions and limited number of mobility tags. As a conclusion, these protocols are able to be implemented into National Service participants tracking application to fulfill the requirements of tracking moving objects
