Abstract: An apparatus, method, and means are provided for seamless and optimized interaction between users, devices, and applications located in a network environment. The applications may be Java or Java-like applications, and the devices may be mobile communication devices.

E-SmallTalker: A Distributed Mobile System for Social Networking in Physical Proximity

Abstract: Small talk is an important social lubricant that helps people, especially strangers, initiate conversations and make friends with each other in physical proximity. However, due to difficulties in quickly identifying significant topics of common interest, real-world small talk tends to be superficial. The mass popularity of mobile phones can help improve the effectiveness of small talk. In this paper, we present E-SmallTalker, a distributed mobile communications system that facilitates social networking in physical proximity. It automatically discovers and suggests topics such as common interests for more significant conversations. We build on Bluetooth Service Discovery Protocol (SDP) to exchange potential topics by customizing service attributes to publish nonservice-related information without establishing a connection. We propose a novel iterative Bloom filter (IBF) protocol that encodes topics to fit in SDP attributes and achieves a low false positive rate. We have implemented the system in Java ME for ease of deployment. Our experiments on real-world phones show that it is efficient enough at the system level to facilitate social interactions among strangers in physical proximity. To the best of our knowledge, E-SmallTalker is the first distributed mobile system to achieve the same purpose.

Improvement of maternal health services through the use of mobile phones

Abstract: OBJECTIVE: To analyse on the basis of the literature the potential of mobile phones to improve maternal health services in Low and Middle Income Countries (LMIC). METHODS: Wide search for scientific and grey literature using various terms linked to: maternal health mobile telecommunication and LMIC. Applications requiring an internet connection were excluded as this is not widely available in LMIC yet. RESULTS: Few projects exist in this field and little evidence is available as yet on the impact of mobile phones on the quality of maternal health services. Projects focus mainly on the delay in receiving care--that is in recognizing the need and making the decision to seek care--and the delay in arriving at the health facility. This is achieved by connecting lesser trained health workers to specialists and coordination of referrals. Ongoing projects focus on empowering women to seek health care. DISCUSSION: There is broad agreement that access to communication is one of several essential components to improve maternal health services and hence the use of mobile phones has much potential. However there is a need for robust evidence on constraints and impacts especially when financial and human resources will be invested. Concurrently other ways in which mobile phones can be used to benefit maternal health services need to be further explored taking into consideration privacy and confidentiality.

Energy Efficient Offloading of 3G Networks

Abstract: The increase in data consumed by smartphones is becoming a huge problem for mobile operators. In three years, mobile data traffic in ATT it is also assisted by predictions made by the operator. We evaluate both algorithms using a large data set, obtained from a major mobile operator and a realistic application similar to Apple's Ping music social network. The metrics address the amount of offloading, delay and mobile energy efficiency. We find that both solutions succeed in offloading a significant amount of traffic, with a positive impact on user battery lifetime. Surprisingly, we also find that all the benefit obtained from the operator with the MixZones algorithm (i.e with ad hoc exchanges between users) can be achieved with the HotZones algorithm and a small investment in Wi-Fi access points. Note that the latter is considerably less complex to deploy than the former.

Mobile cloud sensing, big data, and 5G networks make an intelligent and smart world

Abstract: Through time, we have seen mobile phones transform into multifaceted devices, adapted to meet and exceed our everyday needs. These needs range from something as personal as a health care manager to something as purely analytical as an environment monitor. In effect, mobile phones have come into our lives, making life easier, smarter, and more efficient. In this article we discuss mobile sensing and cloud computing separately and in detail, then combine the two concepts to form the singular idea of mobile cloud sensing. We will also give an intuitive architectural description of mobile cloud sensing, along with discussions about each of its individual building blocks. There are limitations to mobile cloud sensing today, but with the emergence of 5G coupled with the analysis of big data, we can address the current issues at hand. We believe that with the advent of mobile cloud sensing, 5G, and big data analysis, our lives will continue to see an increase in overall quality.
