Delay-tolerant networking (DTN) enables nodes to communicate by means of asynchronous messaging even though no end-to-end path may exist at any point in time. Messages may be of arbitrary size and the (email-style) store-carry-and-forward operation keeps copies of messages in possibly many nodes for an extended period of time. Suitably designed application protocols avoid frequent interactions ...

This paper describes a new monitoring and event management concept. eEMU is a clientserver system that provides for rapid development of monitoring agents. This is thanks to its messaging language that takes advantage of heuristic algorithms implemented in the eEMU server. As opposed to SNMP and other static monitoring methodologies used in system and application monitoring, eEMU takes a whole ...

Enterprise application integration, i.e. an endeavor to make independently developed information systems cooperate, is an important topic of enterprise computing for decades. Despite many efforts, both in industry and academic area, integration solutions development is still often a costly, error-prone process. The goal of presented work is to make messaging-based integration solutions developm...

Rule-based systems and languages are successful in many application areas such as business rules or active database systems. The goal of the Demaq project is to investigate the feasibility and benefits of using a declarative, rule-based programming language to simplify the development of complex, distributed applications. For this purpose, we propose a novel programming paradigm based on messag...

The ability to verify the identity of a mobile subscriber will become increasingly important as the services and information that can be accessed by a cellular handset becomes more wide-ranging and sensitive. Current user authentication for mobile handsets is provided by the Personal Identification Number (PIN), which has a number of inherent weaknesses, such as users writing them down, telling...

The proliferation of heterogeneous devices and diverse networking technologies demands flexible models to guarantee the quality-of-service (QoS) at the application session level, which is a common behavior of many network-centric applications, e.g., Web browsing and Instant messaging. Several QoS models have been proposed for heterogeneous wired/wireless environments. However, we envision that ...

There is growing trend to unify user-to-user messaging systems to allow message exchange, independent of time, place, protocol, and end-user device. Building gateways to interconnect existing messaging systems seems an obvious approach to unification. In this paper we argue that unification should take place at the level of the underlying messaging models. Such a unification results in one mess...

Multimedia messaging is expected to become a major application for next generation mobile computing and communication devices. Heterogeneous capabilities of these devices, however, require adaptation of multimedia messages before rendering on any specific device. To achieve this in case of video messages, video analysis has to be performed to extract the structure of the video and control the m...

Messaging, and distributed transactions, describe two important models for building enterprise software systems. Distributed object middleware aims to support both models by providing messaging and transaction services. But while the concept of distributed object transactions is well-understood, support for messaging in distributed object environments is still in its early stages, and not nearl...

context medication non-adherence is a commonly observed problem in the self-administration of treatment, regardless of the disease type. text messaging reminders, as electronic reminders, provide an opportunity to improve medication adherence. in this study, we aimed to provide evidence addressing the question of whether text message reminders were effective in improving patients’ adherence to ...
