Urinary system disorders may be prevented by achieving a good body hydration level (BHL). This paper investigated a measurement platform set-up for detecting the shade of the (yellow) colour of urine and its integration with the IoT principles for providing ubiquitous services to the users (citizens). We propose a smart IoT-based holistic system that consists of a urine colour measurement component...
Mobile Crowd Sensing (MCS) aims to coordinate and activate the participation of volunteers willing to use their smartphones to harvest large quantities of data as they move in urban areas. One of the most important requirements in MCS is maximizing the effectiveness of the data gathering campaign. In fact, also due to the initial low penetration rate of MCS apps and to avoid making the MCS process...
The interactive demonstration "Scientific Teaching with Tablet PCs" deals with the capabilities of tablets for measurements of physical values and video analysis of motions. The author designed learning scenarios for science teaching in secondary education using sensors and mobile devices in order to enhance the motivation of pupils to deal with scientific issues. These learning scenarios...
A wireless sensor network could be either homogeneous network or heterogeneous network. Depending upon the nature of application requirements a wireless sensor node could either be static or mobile one. When the nodes are static, data collection by the sink from various sources will be difficult and time consuming process. Also static deployment of sink as well as source nodes lead to energy hole...
Driving is an integral part of our everyday lives, and the average driving time of people globally is increasing to 84 minutes everyday, which is a time when people are uniquely vulnerable. A number of research works have identified that mobile crowd sensing in vehicular social networks (VSNs) can be effectively used for many purposes and bring huge economic benefits, e.g., safety improvement and...
For notification distribution, we have designed and implemented a mobile device management system called Meta XA. Meta XA is based on an event-driven architecture combined with the complex event processing technology. In this paper, we propose an approach to bringing Meta XA into the cloud computing domain, without having to change its architecture.
Wireless Sensor Networks are widely used in today's world in several applications ranging from environmental and health monitoring to military uses. Data Collection is one of the most important aspects of WSN and this topic has witnessed significant amount of research over the year. Traditionally static sensors were used in the data gathering process but later on mobile nodes were introduced with...
We examine the design of self-organizing mobile adaptive networks with multiple targets in which the network nodes form distinct clusters to learn about and purse multiple targets, all while moving in a cohesive collision-free manner. We build upon previous distributed diffusion-based adaptive learning networks that focused on a single target to examine the case with multiple targets in which the...
This article addresses the problem of space-partitioning in heterogeneous sensor networks, where the nodes have uniform symmetric sensing patterns, though their maximum sensing distance differs. Inappropriateness of classical spatial Voronoi tessellation for coverage purposes is denoted, compared to the proposed space-partitioning technique, which takes into account this heterogeneity. Unlike weighted-Voronoi...
Target tracking is one of the most popular applications of mobile wireless sensor networks (MWSNs), where coverage and data gathering algorithms are foundations to achieve successful target tracking. Since the mobility of sensor nodes is of great importance in this particular class of application, it is crucial to design efficient techniques that can manage the mobility. In this paper, we particularly...
The blind typically resort to audio feedback to access information on electronic devices. However, this modality is not always an appropriate form of output. Novel approaches that allow for private and inconspicuous interaction are paramount. The intention of this paper is to develop a hand glove which is wirelessly connected to an android device for the visually impaired. The visually impaired gives...
To help unlicensed users to use the maximum available licensed bandwidth, an opportunistic communication technology called cognitive radio, (CR) is developed. It has recently attracted a great deal of research interest. Even though the majority of future wireless devices will be mobile, mobility is yet unexplored in the context of CR. There is no proper framework for mobile CRs to effectively use...
Target Coverage and network connectivity are two main challenging and practically important issues of Mobile Sensor Networks (MSNs). Target coverage covers a set of specified points of interest in the deployment region of a WSN. Target coverage guarantees that every location in the sensing field is covered by at least one sensor and Network Connectivity guarantees that there are sufficient routing...
Certain sensor applications can tolerate sensing data being delivered within certain delay. In such a case, the mobility of sink node can be exploited in conjunction with sensing data buffering to greatly enhance the energy efficiency of data gathering in wireless sensor networks. That is, each sensor node sends its data to a location (called ‘sink site’) over the migration path of the mobile sink...
Most of the wireless sensor networks consist of static sensors that can be deployed in different environments for monitoring purposes. The energy consumption amount of the sensor node is high while transmitting the data from source to static sink node. It results in reduced lifetime of the network. A large number of approaches exist to resolve the above problem. It is found that approaches such as...
Use ol social network services has been more widespread as mobile social network applications have been developed for smart phones. Besides, smart phone sensing, namely Sensing-as-a-Service (S2aaS) provides the front-edge access to the cloud-centric Internet of Things. S2aaS can provide crowdsourced data for several purposes such as public safety, crowd management and environment monitoring. Trustworthiness...
Wireless Sensor Network (WSN) applications require reliable data communication and maximized network lifetime. Both requirements are more demanding in Mobile Wireless Sensor Networks (MWSN) as compared to static WSN. In cluster-based MWSN it is a challenge is to receive data reliably at the cluster-head. This can be achieved by conserving network energy and maintaining reliable connectivity between...
The explosive growth of mobile sensors and smartphones in recent years has contributed to the change of communication manner.

Meanwhile, the popularity of location-based services makes it possible and meaningful to associate with the Proximity-based Mobile Social Networks...
Crowdsensing has appeared as a viable solution for data gathering in many applications with the advent of three emerging paradigms, namely Internet of Things, cloud computing, and mobile social networks. Built-in sensors in mobile devices can leverage the performance of the IoT applications in terms of energy and communication overhead savings by sending their data to the cloud servers. When crowdsensing...
In times of natural or man-made disasters, missions such as safe evacuation of people from the disaster areas have critical importance. Considering large areas with limited vehicle use such as theme parks and state fairs, search and rescue of the pedestrians is a major challenge. Moreover, as an effect of disaster, damages to infrastructure may disrupt the use of Internet services. Therefore, alternative...
