The true potential of the Internet of Things (IoT) will be realized only when devices are able to harness the collective capabilities of a wide range of peer-devices. In this paper, we propose a novel model where friends in a social network can share device capabilities with their peers in an access controlled manner. We develop a theoretical model of such a peer-to-peer network in which devices can search for remote capabilities, and elaborate on the trade-offs of different algorithms in terms of capability searching and execution.

We study various types of social network models to understand the degree of sharing in such networks. Our results show that Barabási-Albert graphs that approximate most real world social networks have a high degree of sharing, validating the utility of our social network based model. We also propose an algorithm that takes any given network and augments it to increase the level of sharing by intelligently suggesting friendship recommendations among vertices. Finally, we describe the prototype implementation of an android mobile application that uses facebook APIs to allow smartphones share GPS and camera capabilities with other devices owned by friends.

Internet of Things (IoT) is a new technology that allows many smart devices to interact with each other after they are connected to the Internet. Smart devices can communicate with each other as well as with other applications to gather useful information/tracking items/provide location which can be used to improve that service or obtain feedback.

In addition, IoT provide new tools to develop more useful application. As a result, we propose a new service called “Share-My-Device”. This service allows interaction between device-to-device and human-to-device.

Nearby future, thing-thing communication form will be the main form along with human-human, and human-thing. To make the things communicate among themselves Internet of Things (IoT) concept is needed. An overview of IoT and why it is going to be formulated will be given. IoT has two attributes and four differential features. The semantic analysis of Internet of things is “the Internet relating to things”, will be discussed. A new concept of energy-efficient routing protocol, Weighted Election Protocol based on Redundancy (R-WEP), in order to enhance the stability period along with network life time of cluster based Wireless Sensor Networks (WSN) for thing-thing communication will be developed.

This paper focuses specifically on a case-monitoring weighted sensor networks based on the weighted election protocol and the reconfiguration of nodes with the principle redundancy to keep coverage of the area and ensure a long life of the network. Flow chart of the new conceptual routing protocol, R-WEP, and the simulation results will be shown comparing with its basic protocol. An idea for application of IoT which mainly concentrates on power minimization will be discussed.

Timeliness is one the most important factors in emergency management. Emergency notification mechanism has to be hassle free and quick, in order to have efficient response for any disaster, health-fix, act of terrorism, etc. In this paper, we present service architecture for emergency alert, using Fog computing. Fog computing brings cloud resources close to the underlying devices and IoTs, which makes it ideal for latency sensitive services. Furthermore, Fog is used for offloading resource constrained devices. Our smart phone based service, known as Emergency Help Alert Mobile Cloud (E-HAMC) provides a quick way of notifying the relevant emergency dealing department, utilizing the services of Fog for offloading as well as pre-processing purposes.

The service sends the location of incident and contacts the appropriate emergency dealing department automatically through already stored contact numbers. The emergency related information is then synchronized automatically from Fog to the Cloud, allowing further analysis and improvement in safety of the people and creates extended portfolio of services for the concerned authorities as well as the users. Performance in most certain scenarios is also evaluated and presented in this study, which shows the applicability of our system and its future prospects.

Supervisory Control and Data Acquisition (SCADA) systems are widely used on industry and public utility services to gather information from field devices and to control and monitor processes. The adoption of Internet technologies in automation have brought new opportunities and challenges for industries, establishing the need to integrate information from various sources on the Web.

This paper exposes the design and implementation of a Resource Oriented Architecture for typical SCADA applications based on the architectural principles of the Representational State Transfer (REST) architectural style. The application to a didactic Flexible Manufacturing Cell illustrates how SCADA can take advantage of the interoperability afforded by open Web technologies, interact with a wide range of systems and leverage from the existing Web infrastructure, such as proxies and caches.

In this paper, a baseband ASIC which supports receive diversity and soft-output Viterbi equalization for enhanced 2G networks is presented. It includes a transmitter and receiver with a symbol detector and a decoder with a dedicated incremental redundancy implementation, as well as the necessary control capability to autonomously communicate with the RF-IC. The ASIC is connected to an RF-IC to build a complete Evolved EDGE transceiver system.

The transceiver system reaches a measured sensitivity close to -112 dBm for single-antenna GSM voice channels and achieves the reference interference performance for adjacent channels 11.4 dB above 3GPP requirements. It is the first reported solution which fulfills the most demanding 3GPP Downlink Advanced Receive Performance Phase 2 testcases specified for Rx-diversity. The ASIC occupies 6 mm ² in 130 nm CMOS with a power consumption between 3.9 and 14 mW.

Recent technological advances have led to an increase in the carbon footprint. Energy efficiency in the Internet of Things (IoT) has been attracting a lot of attention from researchers and designers over the last couple of years, paving the way for an emerging area called green IoT. There are various aspects (such as key enablers, communications, services, and applications) of IoT, where efficient utilization of energy is needed to enable a green IoT environment.

We explore and discuss how the various enabling technologies (such as the Internet, smart objects, sensors, etc.) can be efficiently deployed to achieve a green IoT. Furthermore, we also review various IoT applications, projects and standardization efforts that are currently under way. Finally, we identify some of the emerging challenges that need to be addressed in the future to enable a green IoT.

Mobility-aware cloud services such as fleet management systems need to understand the positions of mobile devices accurately in a real-time manner. Generally speaking, positioning accuracy and data traffic load are in a trade-off relation. Highly accurate real-time positioning requires frequent location data upload and hence results in heavy data traffic load. Although not all data are equally important, data of low importance often consumes a lot of network resources.

This paper presents a data upload control method that the dynamically assesses quality of information (QoI) of measured data at mobile devices. The proposed method balances high accuracy with low traffic loads to achieve efficient vehicle position management. We evaluated the performance of the proposed method using both artificial and actual GPS data and confirmed that it successfully controlled the accuracy and network traffic load according to application requirements.

We are developing new radio architecture for applying a wireless communication system to controlling and monitoring systems in industrial infrastructure systems. Using polarization angle diversity, we can achieve reliable communication in a non line-of-sight situation.

To realize polarization angle diversity, we use a rotating polarized radio wave. When we use polarization angle diversity, we need to control radio frequencies more easily. New software radio architecture create radio frequency in a digital circuit directly. It has a possibility to control a rotating polarization radio wave. And by experiment, I show a result of basic communication test and confirm its functions.

Many Internet of Things (IoT) technologies have been used in applications for money flow, logistics flow, people flow, interactive art design and so on. To manage these increasing disparate devices and connectivity options, ETSI has specified end-to-end M2M system architecture for IoT applications. Based on this architecture we develop an IoT EasyConnect system to manage IoT devices. In our approach, an IoT device is characterized by its “features” (e.g., temperature, vibration, display, etc.) that are manipulated by the network applications.

If a network application handles the individual device features independently, then we can write a software module for each device feature, and the network application can be simply constructed by including these brick-like device feature modules. Based on the concept of device feature, brick-like software modules can provide simple and efficient mechanism to develop IoT device applications and interactions.
