While Wireless Sensor Networks (WSN) are starting to become more popular and used for many applications, developing these applications is still not a trivial task due to many technical challenges such as limited hardware capabilities, communication, and energy resources; high heterogeneity; security; and quality of service (QoS) issues. Recently Service-Oriented Middleware (SOM) has become a preferred...
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...
This paper introduces the concept of middleware for retrieving web information. The Internet provides huge online and updated information related to different aspects of businesses and environments such as stock prices, currency exchange rates, interest rates, and weather information. All this information can be reused for new applications through the proposed middleware. The paper discusses the Internet...
Pervasive and ubiquitous computing evolved tremendously and has become an integral part of many fields. This is widely attributed to their efficiency in integrating with everyday components and handling tasks in a faster and better way. As a result, technologies to facilitate their development, integration and security also evolved. Middleware is an essential component in this field and recently more...
Web alerts are user-defined monitor conditions for public Internet information in which notification messages are sent to users whenever their alert conditions are met. The notification conditions are directly or indirectly and completely or partially based on public information available on the Internet such as news, stock prices, exchange rates, oil price, etc. In some alert services, the user can...
RFID-based systems have started to play a significant role in the automation of many business processes such as ERP systems and object tracking. Several efforts were made within the research community and commercially to enhance the development, deployment and utilization process of these systems. More importantly some research has also started in developing ways to use middleware to facilitate these...
This paper discusses a new flexible system to monitor stocks information available from Web services or dynamic HTML documents. This system allows users to use any public information available on the Internet for defining notification criteria. This opens up a huge repository of dynamic information related to stock investments such as current stock prices, daily trading volumes, current offer prices...
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 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...
Collaborative resource discovery mechanisms are available for environments with stationary to semi- stationary resources. Yet in pervasive computing environments, where all nodes are mobile and many of which connect in and ad hoc manner, incorporating those dynamic mobile resources introduces a new set of requirements. The main issue is the lack of a reference point - a minimum of one stationary node...
As technology advances in the communications and robotics fields and their main technologies, networked robots can offer a wide range of applications. Furthermore, most networked robotic systems consist of a collection of components (being multiple robots working together, multiple components working together within one robot or robots working with other external systems such as wireless sensor networks...
In this paper, we introduce a middleware framework for collaborative resource discovery in pervasive environments. Collaborative resource discovery mechanisms are available to handle static to semi- static resources. However, incorporating dynamic mobile users introduces a different set of problems. First, how do we know when a resource becomes available? How do we identify the resource, its current...
MuniSocket (multiple-network-interface socket) provides mechanisms to enhance the communication performance properties such as throughput, transfer time, and reliability by utilizing the existing multiple network interface cards between a pair of computers. Although the MuniSocket model has some communication performance advantages over the regular socket, it has a number of configuration complexity...
The integration of networked applications, especially those requiring continuous access to shared information resources and databases, may be effected by scheduled unavailability of one or more of these applications. The scheduled unavailability usually occurs due to a number of reasons including application or data backup, software or hardware maintenance for the application's platform, executing...
In this paper, we introduce a collaborative resource discovery mechanism to enhance system resource allocation and utilization by the distributed applications. The mechanism involves the collaboration of the software agents to collect, organize and efficiently exchange resources information. The main goal is to provide an accurate single system image for all the resources. The concept of virtual clusters...
