Nanobiosensors are an interesting topic of research. However, interfacing with a nanobiosensor requires an analyser system. A number of researchers have proposed different system architecture to interface with nanobiosensors. In this paper, comparison of the existing system architectures for nanobiosensors is discussed. Criteria in designing nanobiosensor system architecture is evaluated, such as...
This work demonstrates a simple home automation system that allows the user to control home appliances through wireless. Lights, air conditioners, electronic doors and fans are among the appliances that can be used in this system. In this system, the controlling and monitoring the appliances can perform in two methods. The first method is through a web server meanwhile the second method is by using...
Biological sequence alignment is time-consuming tasks. This is due to its repetitive alignment matrix scores calculations. The SSEARCH35 is the well-known ‘software-only’ sequence homology search tool. However, its sequential execution requires quadratic time complexity even when the software is executed in a sophisticated computer. Alternatively, sequence alignment is executed in hardware such as...
Nowadays, Auto-navigation robots are cutting-edge and widely used and investigated by robotics experts. An autonomous robot can function and complete every task without any human guidance. Since it functions without human intervention, therefore obstacles detection and localization are significant and need to figure out. First, how the robot obstacle detection? Second, how to control auto-navigation...
The complexity to autonomous-navigate a flying robot is much higher compared with a ground-based robot. During autonomous-navigation, the flying robot should have the intelligent to fly from current location toward the desired location. Therefore, the system must address three problems facing by the flying robot. First, where am I? It's the perceive level of the flying robot to sense the environment...
The Internet of Things (IoT) comprises a complex network of smart devices, which frequently exchange data through the Internet. Given the significant growth of IoT as a new technological paradigm, which may involve safety-critical operations and sensitive data to be put online, its security aspect is vital. This paper studies the network security matters in the smart home, health care and transportation...
This project is dedicated towards the designing and developing of an indoor positioning tracking application system with the most optimum characteristics. This is because the Global Positioning system (GPS) is not suitable to be used indoors due to signal lost within contact of building walls. The indoor positioning system is based on the application of Wi-Fi access points found abundantly in smart...

This paper presents the link budget analysis for free space optical (FSO) communication and the studies on how to reduce the attenuation effect to improve FSO link. The effects are primarily focused on the atmospheric attenuation on the received power. Transmission power is the main priority in link budget. The power used to transmit data is gradually decreased along the path due to attenuation effects...
This paper demonstrates the effect of haze condition on free space optical (FSO) communication and to thin out the attenuation effects. The effects in the main focus on the atmospheric attenuation effects due the visibility and link range (length). Visibility is the main concern in utilizing the FSO communication system. The higher visibility, the longer transmission link. Hence, FSO performance could...
