Supporting Adaptive Real-time Mobile Communication with Multilayer Context Awareness

Embedded systems are supporting the trend of moving away from centralised, high-cost products towards low-cost and high-volume products; yet, the non-functional constraints and the device heterogeneity can lead to system complexity. In this regard, Service-Oriented Architecture (SOA) is the best methodology for developing a loosely coupled, dynamic, flexible, distributed, and cost-effective application. SOA relies heavily on services, and the Semantic Web, as the advanced form of the Web, handles the application complexity and heterogeneity with the help of ontology. With an ever-increasing number of similar Web services in UDDI, a functional description of Web services is not sufficient for the discovery process. It is also difficult to rank the similar services based on their functionality. Therefore, the Quality of Service (QoS) description of Web services plays an important role in ranking services within many similar functional services. Context-awareness has been widely studied in embedded and real-time systems and can also play an important role in service ranking as an additional set of criteria. In addition, it can enhance human-computer interaction with the help of ontologies in distributed and heterogeneous environments. In order to address the issues involved in ranking similar services based on the QoS and context-awareness, the authors propose a service discovery framework for distributed embedded real-time systems in this chapter. The proposed framework considers user priorities, QoS, and the context-awareness to enable the user to select the best service among many functional similar services.

Multiple Threads

With the rapid development of communication technology, wireless internet technology and the increasing number of mobile phone users, people were more concern on the efficiency of real-time information service. Based on communication mechanism of multiple threads, a data delivery controller for mobile phone communication was presented in this paper. The server side controller designed on Java multiple threads and provided efficiency data response for request of android mobile phones. By our experiment, the average response time on the server was 3.8s on ten million times addition calculation, which can effectively meet the real-time requirements of mobile communication.

The World

In the past few years, all over the world, crime against children has been on the rise, and parents always worry about their children whenever they are outside. For this reason, tracking and monitoring children have become a considerable necessity. This paper presents an outdoor IoT tracking system which consists of a child module and a parent module. The child module monitors the child location in real time and sends the information to a database in the cloud which forwards it to the parent module (represented as a mobile application). This information is shown in the application as a location on Google maps. The mobile application is designed for this purpose in addition to a number of extra functions. A Raspberry Pi Zero Wireless is used with a GSM/GPS module on shield to provide mobile communication, internet and to determine location. Implementation results for the suggested system are provided which shows that when the child leaves a pre-set safe area, a warring message pops up on the parent’s mobile and a path from the current parent location to the child location is shown on a map.

There is a clear need to enhance security action to prevent any malicious use or inadvertent abuse of radiation sources. Some of these radioactive sources are consistently transferred beyond the office or laboratory grounds for work and consulting reasons. This paper presents the early development of the radioactive citation tracking, which combined the Arduino microcontroller, Global Positioning System (GPS) and Global Mobile Communication System (GSM) systems. The monitoring scheme will assist the proprietor track the motion of irradiated sources. The system is completely capable of monitoring the motion of the toxic substance through GPS satellite signals. The GPS position could either be transferred to the headquarters at a set intervalShort Messaging Service (SMS) enables real-time surveillance or storage on a flash drive for offline surveillance and information capturing..

New Applications

The computing paradigm based on the giant-like DC is replaced by a new paradigm. The urgency of this shift is caused by the requirements of new applications that actively use video, real-time interactivity, new mobile communication technologies, which today cannot be implemented without the usage of cloud computing and virtualization based on SDN&NFV technologies. The presentation considers the requirements dictated by these applications, outlines the architecture of this new paradigm which we call Hierarchical Edge Computing (HEC). Attention is focused on the fact that all these applications are distributed, become more and more real-time applications and require guaranteed quality of service in the networking operation. The main scientific problems that need to be solved for implementing this new paradigm are discussed.
