Sensor networks can be used to monitor and control pipeline infrastructures. This paper discusses and compares different sensor network architectures that can be used for monitoring underwater pipelines infrastructures. These architectures are underwater wired sensor networks, underwater acoustic wireless sensor networks, RF (Radio Frequency) wireless sensor networks, integrated wired/acoustic wireless...
Different simulation tools are available to the research community which can be used to validate, test and evaluate networking protocols. Such simulation software packages include OPNET, ns-2 and others. These programs are capable of performing relatively accurate simulations of networking architectures including wireless, ad hoc, and sensor networks. Although they are very useful for a wide range...
Considerable advancements in the technology of wireless sensor networks (WSNs) are taking place due to smaller, and more efficient electronic devices which are capable of increased processing power, and communication capabilities. In addition, the cost of such devices is constantly decreasing, which makes it possible to employ large quantities of networked sensors in numerous commercial, environmental,...
Project-based learning (PBL) is becoming an integral part of many information technology (IT) courses. Students are guided through individual or group projects to learn and apply many of the IT concepts they learn in a course. However, a significant percentage of IT projects depend on the existence of large sets of information or live data. Therefore, it becomes difficult to complete and properly...
The field of robotics relies heavily on various technologies such as mechatronics, computing systems, and wireless communication. Given the fast growing technological progress in these fields, robots can offer a wide range of applications. However real world integration and application development for such a distributed system composed of many robotic modules and networked robotic devices is very...
This paper proposes a new fault-tolerant sensor network architecture for monitoring pipeline infrastructures. This architecture is an integrated wired and wireless network. The wired part of the network is considered the primary network while the wireless part is used as a backup among sensor nodes when there is any failure in the wired network. This architecture solves the current reliability issues...
This paper presents a reliable routing protocol for wireless ad hoc and sensor networks which is based on the DSR routing protocol. The protocol achieves increased reliability through the maintenance of a reliability factor by the nodes in the network. During the route discovery process, the request messages are only propagated to nodes with a reliability factor that is above a threshold value specified...
This paper introduces a framework to monitor information available dynamically on the Internet through Web services, RSS feeds or dynamic HTML documents based on user defined criteria. The paper also discusses some of the open issues associated with the design and application of the framework. This framework is designed to deal with public information available on the Internet on a single or multiple...

IEEE 802.15.4 (Zigbee) is the new standard that has been developed for low cost, low data rate and low power consumption wireless network. This paper provides a brief description of this standard including the physical (PHY) and medium access control (MAC) layer. It focuses on developing MatLab/Simulink models for the Zigbee protocol and the performance evaluation of these models. Simulation has been...
With the continued increase of speed and capacities of computing devices and the growing needs of people for mobile computing capabilities, Mobile ad hoc networks (MANETs) have gained a lot of interest from the research community. Quality of service (QoS) provisioning in MANETs is an essential component that is needed to support multimedia and real-time applications. On the other hand, directional...
