Remote Network Monitoring System (RNMS)

Nowadays, computer networks become very complex. Thousands of nodes distributed in various places. Within this complexity, it has become impossible task to monitor large networks by human effort only. Thus, there are urgent needs to find convenient solutions to help networks managers in managing and monitoring their networks. This study presents a monitoring system, named Remote Network Monitoring System (RNMS). The proposed system empowered the networks mangers to remotely monitor their network’s computers. Therefore, a web-based monitoring system has been designed using UML models, and then the system has been developed using ASP.Net with VB.Net scripts. The proposed system is based on SNMP (Simple Network Management Protocol). The SNMP provides efficacious means to access the remote agent’s MIB’s (Management Information Base) objects. Furthermore, this study has evaluated and tested the RNMS using the verification test (unit, integration, and system testing), and the validation test (user acceptance test) based on TAM (Technology Acceptance Model)

Using a simple expert system to assist a powered wheelchair user

A simple expert system is described that helps wheelchair users to drive their wheelchairs. The expert system takes data in from sensors and a joystick, identifies obstacles and then recommends a safe route. Wheelchair users were timed while driving around a variety of routes and using a joystick controlling their wheelchair via the simple expert system. Ultrasonic sensors are used to detect the obstacles. The simple expert system performed better than other recently published systems. In more difficult situations, wheelchair drivers did better when there was help from a sensor system. Wheelchair users completed routes with the sensors and expert system and results are compared with the same users driving without any assistance. The new systems show a significant improvement
