Network security is defined as a set of policies and actions taken by a network administrator in order to prevent unauthorized access, penetrated the defenses and infiltrated the network from unnecessary intervention. The network security also involves granting access to data using a pre-defined policy. A network firewall, on the other hand, is a network appliance that controls incoming and outgoing traffic by examining the traffic flowing through the network. This security measure establishes a secure wall [firewall] between a trusted internal network and the outside world were a security threat in shape of a hacker or a virus might have existed
In the context of keeping the elderly healthy and safe and with the development of the modern small energy efficient technology, with the help of a health monitoring device (HM) as a main activity. The Cloud-based IoT architecture contains a cloud computing and the Internet of Things In order to focus on the advantages that was derived from the complementarities. The sensing services is focused on the development of the sensors data usage and accessibility. beginning from the general scenarios of this service, this paper discusses a Human Machine-oriented Sensing Service scenario with the goal to make the quality of the service and its implementation, taking In consideration the demanding interests of this service which doesn't come only from big medical facilities but also from general practitioners and small clinics. A mathematical model for simulating induced hyperglycemia and hypoglycemia and a smartwatch application is implemented for the patient as well as the health monitoring company (HMC) and the cloud infrastructure for the data to be stored was designed as well as the infrastructure necessary for the patient to run the solution in his/her home.
Using sustainable energy is the future of our planet earth, this became not only economically efficient but also a necessity for the preservation of life on earth. Because of such necessity, smart grids became a very important issue to be researched. Many literatures discussed this topic and with the development of internet of things (IoT) and smart sensors, smart grids are developed even further. On the other hand, software defined networking is a technology that separates the cntrol plane from the data plan of the network. It centralizes the management and the orchestration of the network tasks by using a network controller. The network controller is the heart of the SDN-enabled network, and it can control other networking devices using software defined networking (SDN) protocols such as OpenFlow. A smart switching mechanism called (SDN-smgrid-sw) for the smart grid will be modeled and controlled using SDN. We modeled the environment that interact with the sensors, for the sun and the wind elements. The Algorithm is modeled and programmed for smart efficient power sharing that is managed centrally and monitored using SDN controller. Also, all if the smart grid elements (power sources) are connected to the IP network using IoT protocols.
Robotic arm plays a great role in assisting the human hand in current life. This project involves the design and implementation of two degrees of freedom (DOF's) assistant arm robot for aiding humans in the medical recovery for the upper left limb motion. The contribution in this work involves three parts: the first one, design special interfacing circuits based on (Arduino card) for controlling the designed arm motion, where the motion execution and record is done by designed reading and writing circuits, these circuits controlled by a designed MATLAB fuzzy proportional derivative (PD) controller, this control structure implemented by assisting of special Arduino Simulink library In MATLAB Simulink, where it will be used for control the signals transition, a new Simulink design proposed and investigated to interfacing the controller with the arm motors and encoders via the circuits. The second contribution is adding an assisting spring system to the arm first motor joint, where this addition rises the motion stability through the control phase by increasing the required torque in the arm first joint, especially after the human hand load is attached to the robot links, where its tested effectively without needing for replacing the motor with increased torque. The results illustrate the power of these circuits design and the error reduction occurred after supporting the system's spring. The Third contribution, An Internet of robotic thing (IoRT) model is designed, and then the robot arm is connected using our designed internet -based control system using IoT protocols for communication.
