In this paper, we describe the design and implementation of an UDP-based socket that utilizes multiple network interface units connected through one or more networks. The socket is a middleware layer that provides abstract network APIs to hide low-level technical details from users. Parallel message fragmentation and reconstruction techniques and a reliable(More)
Using middleware to bridge the gap between applications and low-level constructs is a novel approach to resolving many wireless sensor network issues and enhancing application development. This survey discusses representative WSN middleware, presenting the state of the research. The emerging field of tiny, networked sensors offers an unprecedented(More)
— Ad hoc and sensor networks is a new area of research which is rapidly growing due to the development of new technologies in inexpensive sensors. These electronic devices have increased capabilities in processing speed, memory, communication and networking [21][22]. Such sensor networks have a vast amount of applications including environmental monitoring,(More)
Recently there has been an increasing interest in developing parallel programming capabilities in Java to harness the vast resources available in clusters, grids and heterogeneous networked systems. In this paper, we introduce a Java object-passing interface (JOPI) library. JOPI provides Java programmers with the necessary functionality to write(More)
As the costs of healthcare services rise and healthcare professionals are becoming scarce and hard to find, it is imminent that healthcare organizations consider adopting health information technology (HIT) systems. HIT allows health organizations to streamline many of their processes and provide services in a more efficient and cost-effective manner. The(More)
This paper develops and compares different sensor network architecture designs that can be used for monitoring underwater pipeline infrastructures. These architectures are underwater wired sensor networks, underwater acoustic wireless sensor networks, RF (radio frequency) wireless sensor networks, integrated wired/acoustic wireless sensor networks, and(More)
— The use of middleware has extended from simply facilitating applications' communication to a broad set of services supporting a huge spectrum of networked and distributed computing environments. At the same time mobile wireless ad hoc networks (MANET) have become a popular distributed environment and its application domain is expanding rapidly. However,(More)
