New regulations require living kidney donor (LKD) follow‐up for 2 years, but donor retention remains poor. Electronic communication (eg, text messaging and e‐mail) might improve donor retention. To explore the possible impact of electronic communication, we recruited LKDs to participate in an exploratory study of communication via telephone, e‐mail, or text messaging postdonation; communication through...
Mobile medical applications are increasingly being used by patients and consumers. However, due to their complexity, these applications are normally only accessible to smartphone users. People using low-end cellphones cannot benefit from this new technology. The goal of this paper is to expand health service platform to lower-end cellphones, so that people in underdeveloped regions can benefit from...
NetsBlox is a visual blocks-based programming language extending Snap! with a few carefully selected abstractions to support distributed programming. In this paper, we argue that with the help of NetsBlox, some of the fundamental concepts of computer networking can be included in the high school computer science curriculum. Specifically, we describe a set of curricular units that would fit nicely...
As the ubiquity of computers, computer-mediated communications (CMC) has evolved to satisfy one of humanity's basic needs — communication today. Text-based message exchanging has established itself as the most popular CMC medium in our lives than other modes of communication. Compared to face-to-face communication, CMC is not restricted in terms of time and place However, text-based communications...
Existing ad-hoc wireless communications systems are based around Wi-Fi communications, owing to the ubiquity and cost-effectiveness of Wi-Fi; no other open wireless communications channel offers the capabilities and benefits of mass-production consumer markets. However in some situations even long-range directional Wi-Fi links are not suitable. For example Pacific nations spread over island groups...
E-health applications are methods used by medical practitioners to assess and follow their patients' mental and physical conditions. They may also provide feedback to patients and help them to change their behavior. Our research project aims to propose a mobile application (app in short) for suicide prevention. The principle is to develop a connected tool used by the patient to report about his/her...
The paper does concern the IM (Instant Messaging) system with a cryptographic feature designed for the portable subscriber appliances working with the Android operating system. Unlike the existing applications with a text messaging function, the proposed system uses XML (Extensible Markup Language) tool to specify the message structure and in order to ensure appropriate confidentiality of talks it...
The object of this paper is to express influence of OTT service providers on Croatian telecommunication market in comparison with some European countries and United States based on mobileSQUARED research. As part of the project “Looking to the future”, the authors conducted a questionnaire about the impact of OTT service providers on the Croatian telecommunications market. The questionnaire has been...
Short Message Service (SMS) via cell phones is a widely used mode of data communication. Currently employed encoding schemes allow the transmission of 160 characters per SMS in English. This drops to 70 characters per SMS if any Indian language including Hindi is used, due to the UNICODE format used therein. Schemes proposed to improve the encoding efficiency of short text messaging generally encode...
Electronic fare management is a subject currently intensively discussed all over. A lot of different solutions have been implemented in the past. But a new kind of solution was coming up in the last few years: mobile ticketing. This ticketing concept uses customer's mobile devices to buy public transport tickets, instead of special devices owned by the transport operators.Another topic of discussion...
A one-time pad (OTP) can be conceived of as a stream cipher where the plaintext and key have equal length and the key is never reused. This cipher has easily proven properties of deniability and mathematical unbreakability, even in situations where an eavesdropper has access to unlimited computing power. Yet OTPs also have non-intuitive bottlenecks in CPU, RAM, disk I/O, and key material consumption,...
This research shows how electronic messaging systems (EMS) are being used, increasingly frequently, by users of mobile services, the user preference for the different systems currently available of electronic messaging and type mobile devices being used as the means to send and receive text messages. The research is also intended to determine the preference of users to send a text message instead...
Mobile phone theft has been a growing problem of modern society, but it is difficult to recover lost phones because owners often have no clue to culprits. To address the problem, we propose MMSnap, a new forensic system based on Multimedia Messaging Service (MMS) for recovering stolen phones. When a user finds his phone has been stolen, he simply calls the phone using a predefined number saved in...
In Delay Tolerant Networks (DTNs), message forwarding is a challenging open problem because of low node density and lack of global information. Most of the previous forwarding methods select a node as a relay node with the best cumulative and global ability of contacting the destination without considering the maximum message acceptable delivery latency. However, if the network is composed of several...
Delay Tolerant Networks are the kind of networks in which an end-to-end path between any source and destination pair may never exist. In these networks, nodes use store-carryforward mechanism for data transmission. In this mechanism, nodes store the messages in their buffers and carry them to reach the appropriate forwarding chance. Most of the previous efforts on improving the performance of routing...
To strengthen collaboration between hospitals and community healthcare in Norway, an electronic messaging system was introduced. We argue that technology support for collaboration can be understood in terms of the concepts of collaboration embedded in the technology (workflow, information exchange, and communication). We analyze the e-messaging system from these three perspectives and show that its...
Optimizing the three most important network performance parameters i.e. Delivery probability, Overhead ratio, and Delay is challenging in Delay Tolerant Networks (DTN) due to high occurrences of network partitioning in these networks. Owing to the partitioning nature efficient routing or dissemination of messages is important in DTN. In this paper, we focused to improve the spray phase of Binary Spray...
The resilience of communications is constantly tested during and after a major disaster. For this reason companies are creating innovative ways to ensure communication is maintained between the emergency services. Mobile communications have become integral to how emergency services respond to major incidents. The aftermath of the 2005 7/7 London terrorist bomb attacks saw mobile phone networks overloaded...
This paper presents a framework based on cellular telephony technologies using the short message service (SMS) and wireless application protocol (WAP) to assist effectively in the remote monitoring and control of an enterprise computer network. The work proposes a network monitoring architecture integrated with WAP and SMS to support the connectivity between network and Internet/GSM networks. System...
In this paper we present the DLM 3.0 project's vision for e-mail communication in enterprise. The project promotes the use of semantic techniques, based on case studies and ergonomic analysis to improve current email tools, in an enterprise context. The project's realm is to create a corporate social network centered on email, with email being connected to the company tools, and automatically interacting...
