The paper reported a field survey that sought to examine the technical implications in the adoption of a Global System for Mobile communication GSM-based metering system in the New Juaben Municipality. Both simple random sampling and interview guide methods were used. The issues considered under the study were; understanding of a GSM-based metre reading, mobile phone penetration among consumers, reliability...
The use of wearable devices is becoming more frequent, especially when it comes to monitoring heart rate in physical activity. The use of information from "wearable" devices in the area of "fitness" is a common practice, however, in the context of health and clinical decision making it is not usual to use the information obtained through by such devices. Doubts as to their reliability...
The accuracy of measurement-driven mobile coverage maps depends on the quality, density and pattern of the signal strength observations. Thus, identifying an efficient measurement data collection methodology is essential, especially when considering the cost associated with the measurement collection approaches (e.g., drive tests, crowd approaches). We propose ZipWeave, a novel measurement data collection...
An ever-increasing number of today's mobile applications take advantage of location-based services (LBS) in order to proactively notify mobile users about location-dependent content or to execute location-dependent actions once the user enters or leaves a dedicated zone. The proactive LBS are thereby responsible to track the user's position energy-efficiently in the background and to continuously...
Medical data are crucial for providing reliable mobile health services. However, its reliability may be degraded due to internal factors related to performance variations of mobile technologies used in the application and other external ones such as the environmental ones. This paper addresses this problem by proposing an ontology-based approach to deal with data and reliability management in mobile...
To satisfy the increasing demand of wireless sensor network (WSN) distribution in the different monitoring area and enlarge the coverage of the WSNs in various scenes of application, in this paper, we constructed a new type of mobile wireless data sinking platform for collecting the data of WSN based on the technology of unmanned aerial vehicle (UAV). First, the authors studied a wireless environmental...
Mobile Adhoc Network (MANET) is extremely susceptible to more attacks owing to its characteristics such as mobility and dynamic topology changes. In particular, routing process in MANET is aimed by more adversaries for various attacks to ruin the data transmission. In this paper, we introduce a combined technique for attack monitoring and risk assessment in MANET routing. The proposed solution chooses...
Wireless sensor networks offer a pragmatic solution for monitoring in a variety of scenarios. For efficient and practical data gathering, especially in large-scale systems deployed in inaccessible areas, unmanned vehicles are becoming a compelling solution. The added infrastructure flexibility comes at the cost of limited contact time between the mobile entity and the stationary devices. The channel...
Recently, induced by incorporating the ubiquitous data gathering capability of wireless sensor networks (WSNs) as well as the powerful data storage and data processing abilities of cloud computing (CC), WSN-CC integration is attracting growing interest from both academia and industry. However, WSN-CC integration is still in its infancy and a lot of research efforts are expected to emerge in this area...
Mobile cloud computing is a powerful technology for supporting the growing demand of mobile applications. Unfortunately, existing mobile cloud service architectures are imperfect since mobile devices are not considered as the available resources. In this paper, a general framework is proposed that regarding mobile devices as resources by introducing proxy. Differs from other architectures, this framework...
This paper aims at using the novel concept of LTE-based Device-to-Device communications (D2D) as a new alternative for Intelligent Transportation Systems (ITS) vehicular communications in advanced 4G networks and beyond. We propose the Cellular Vehicular Network (CVN) solution as a reliable and scalable operator-assisted opportunistic architecture that supports hyper-local ITS services as 3GPP Proximity...
To improve the response time of the system operator, a robust monitoring system is recommended. Design of such system is done so as to impart additional intelligence to the conventional monitoring system by creating logical analytics, using abnormality / limit violation of important parameters such as frequency, flow gate limits etc. or using combination of two or more such parameters. Further, the...

Using electronic transaction instead of manual ones is an easy way to facilitate business process automation. A cost effective option of introducing electronic transactions in public systems with high number of users is applying contactless cards and the related contactless infrastructure. The spreading of Near Field Communication (NFC) compatible mobile devices made relatively easy the implementation...
Mobility management in Wireless Sensor Networks is considered to be of an up most importance for today's critical applications. In this paper, we present a soft mobility management solution where the mobility procedures are supported by fuzzy logic techniques. Our solution was designed and implemented to support the movement of a mobile worker inside an oil refinery area. The results show that the...
In pervasive computing system, the increasing dynamic and complexity of software and hardware resources and frequentative interaction among function components make fault-tolerant design very challenging. In this paper, we propose a novel self-adaptive fault-tolerant mechanism for a dynamic pervasive computing environment such as mobile ad hoc network.

As an advanced technology for information sensing and transmission, Internet of Things (IoT) has been applied extensively in the power generation, transmission, substations, distribution, utilization and other processes, and will develop with broad prospect in Smart Grid. This paper focuses on IoT application in transmission lines. A networking strategy for transmission line on-line monitoring system...
In the environment of Mobile Ad-hoc Networks (MANETs), devices can collaborate under the service-oriented architecture (SOA). However, as MANETs are infrastructure-less, devices may move randomly and join and leave the network at any time which leads to a permanently changing topology of the network. What adds to the unpredictability of the network is the limited resource of the nodes, including battery...
