Editor's Notes
- The legacy telecom ecosystem has been designed considering voice as the major service provided on networks. The entire operations related to network optimization, monitoring, performance and customer experience was built around voice and a bit of data on it. It has become imperative to analyse how networks behave in data intensive traffic, to address the challenges related to customer acquisition and retention. There is a need for new tools and solutions for analysing this paradigm.
- The legacy telecom ecosystem has been designed considering voice as the major service provided on networks. The entire operations related to network optimization, monitoring, performance and customer experience was built around voice and a bit of data on it. It has become imperative to analyse how networks behave in data intensive traffic, to address the challenges related to customer acquisition and retention. There is a need for new tools and solutions for analysing this paradigm.
- With proliferation of smartphones and app-based solutions, the revenue had shifted from voice to data and data related services. In 2017, telecom operators realised that the revenue was not just dependent on voice and data and data related solutions but video as well. Though TV is still the major video viewing platform, over the top (OTT) video habit has risen among the GenY who want to view videos online secluded from others in the family. After 2017, in order to improve the viewing experience of online video, technologies like augmented reality (AR) and Virtual Reality (VR) will gain traction. Internet of Things(IoT) will be enabled by wide spread 4G adoption.
- telecom operators want to utilise new age technologies such as automation, robotics, Machine Learning(ML), Artificial Intelligence(AI), network virtualisation, software defined networks(SDN) and self-optimising networks (SON) to address the current challenges and make the networks future-proof. Telecom operators are embracing these technologies at various levels of maturity and will expand their adoption based on the demands of the existing systems and development of advanced service capabilities.
- By 2020 the Internet traffic will shift dramatically!. Most of the IP traffic will originate from other than personal computers (PCs). Wi-Fi traffic will exceed wired traffic and Full HD video will generate more traffic than standard video. According to a recent report issued by Cisco, the number of connected devices (i.e. through IPv6 and evolution) will grow to some 50 billion devices by 2020. The internet traffic will get close to 44 Zettabytes (i.e. 10^21 bytes)! In the Football World Cup in Brazil (June 2014), the Video streaming and internet broadcasting have generated 4.3 Exabytes (i.e. 10^18 bytes) of IP traffic, which is 3X the monthly IP traffic typically generated by Brazil.
- M2M has been around for several decades now Some deployments date back more than 20 years. However M2M markets are struggling to realise the full M2M market potential What exactly is Internet of Things : Smart Systems and the Internet of Things are driven by a combination of Sensors & Actuators, Connectivity, People & Processes Trillion Dollar Opportunity - Unlimited possibilities; Harbor Research – $180 Billion in 2014 will grow to $1 Trillion IDC forecasts - The worldwide market for IoT solutions will grow from $1.9 trillion in 2013 to $7.1 trillion in 2020 Cisco - $19 trillion forecast for the economic value created by the “Internet of Everything” by 2020 India and China are biggest contributor..
- The term “Internet of Things” (IoT) was first used in 1999 by British technology pioneer Kevin Ashton to describe a system in which objects in the physical world could be connected to the Internet by sensors. Ashton coined the term to illustrate the power of connecting Radio-Frequency Identification (RFID) tags used in corporate supply chains to the Internet in order to count and track goods without the need for human intervention
- The IoT is expected to greatly integrate leading technologies, such as technologies related to advanced M2M communication, autonomic networking, data mining and decision-making, security and privacy protection and cloud computing, with technologies for advanced sensing and actuation.
- The fundamental characteristics of the IoT are: Interconnectivity: Anything can be interconnected with the global information and communication infrastructure. Things-related services: The IoT is capable of providing thing-related services within the constraints of things which requires changes in the technologies for both physical world and information world. Heterogeneity: The devices in the IoT are heterogeneous as based on different hardware platforms and networks. They can interact with other devices or service platforms through different networks. Dynamic changes: The state of devices change dynamically, e.g., sleeping and waking up, connected and/or disconnected as well as the context of devices including location and speed. Moreover, the number of devices can change dynamically. Enormous scale: The magnitude of number of devices that need to be managed and that communicate with each other will be much larger than the devices connected to the current Internet. The ratio of communication triggered by devices as compared to communication triggered by humans will noticeably shift towards device-triggered communication. Even more critical will be the management of the data generated and their interpretation for application purposes. This relates to semantics of data, as well as efficient data handling.
- The following provide high-level requirements which are relevant for the IoT: Identification-based connectivity: The IoT needs to support that the connectivity between a thing and the IoT is established based on the thing's identifier. Also, this includes that possibly heterogeneous identifiers of the different things are processed in a unified way. Interoperability: Interoperability needs to be ensured among heterogeneous and distributed systems for provision and consumption of a variety of information and services. Autonomic networking: Autonomic networking (including self-management, self-configuring, self-healing, self-optimizing and self-protecting techniques and/or mechanisms) needs to be supported in the networking control functions of the IoT, in order to adapt to different application domains, different communication environments and large numbers and types of devices. Autonomic services provisioning: The services need to be able to be provided by capturing, communicating and processing automatically the data of things based on the rules configured by operators or customized by subscribers. Autonomic services may depend on the techniques of automatic data fusion and data mining. Location-based capabilities: This need to be supported in the IoT. Something-related communications and services will depend on the location information of things and/or users. It is needed to sense and track the location information automatically. Location-based communications and services may be constrained by laws and regulations, and should comply with security requirements. Security: In the IoT, every 'thing' is connected which results in significant security threats, such as threats towards confidentiality, authenticity and integrity of both data and services. A critical example of security requirements is the need to integrate different security policies and techniques related to the variety of devices and user networks in the IoT. Privacy protection: Privacy protection needs to be supported in the IoT. Many things have their owners and users. Sensed data of things may contain private information concerning their owners or users. The IoT needs to support privacy protection during data transmission, aggregation, storage, mining and processing. Privacy protection should not set a barrier to data source authentication. High quality and highly secure human body related services: Human body related services refer to the services provided by capturing, communicating and processing the data related to human static features and dynamic behaviour with or without human intervention. Different countries have different laws and regulations on these services. Plug and play: Plug and play capability needs to be supported in the IoT in order to enable on-the-fly generation, composition or the acquiring of semantic-based configurations for seamless integration and cooperation of interconnected things with applications, and responsiveness to application requirements. Manageability: Manageability needs to be supported in the IoT in order to ensure normal network operations. IoT applications usually work automatically without the participation of people, but their whole operation process should be manageable by the relevant parties.
- There are six main elements to deliver the functionality of the IoT: 1. Identification: Identification is identification methods - Electronic product codes (EPC) and ubiquitous codes (uCode). Ucode- 128 bits. Ucode is application and technology agnostic. Furthermore, addressing the IoT objects is critical to differentiate between object ID and its address. Object ID refers to its name such as “T1” for a particular temperature sensor and object’s address refers to its address within a communications network. In addition, addressing methods of IoT objects include IPv6 and IPv4. 6LoWPAN, provides a compression mechanism over IPv6 headers that makes IPv6 addressing appropriate for low power wireless networks. Distinguishing between object’s identification and address is imperative since identification methods are not globally unique, so addressing assists to uniquely identify objects. In addition, objects within the network might use public IPs and not private ones. Identification methods are used to provide a clear identity for each object within the network. 2. Sensing The IoT sensing means gathering data from related objects within the network and sending it back to a data warehouse, database, or cloud. The collected data is analyzed to take specific actions based on required services. The IoT sensors can be smart sensors, actuators or wearable sensing devices. For example, companies like Wemo, revolv and SmartThings offer smart hubs and mobile applications that enable people to monitor and control thousands of smart devices and appliances inside buildings using their smartphones. Single Board Computers (SBCs) integrated with sensors and built-in TCP/IP and security functionalities are typically used to realize IoT products (e.g., Arduino Yun, Raspberry PI, BeagleBone Black, etc.). Such devices typically connect to a central management portal to provide the required data by customers. 3. C. Communication The IoT communication technologies connect heterogeneous objects together to deliver specific smart services. Typically, the IoT nodes should operate using low power in the presence of lossy and noisy communication links. Examples of communication protocols used for the IoT are WiFi, Bluetooth, IEEE 802.15.4, Z-wave, and LTE-Advanced. Some specific communication technologies are also in use like RFID, Near Field Communication (NFC) and ultra-wide bandwidth (UWB). RFID is the first technology used to realize the M2M concept (RFID tag and reader). The RFID tag represents a simple chip or label attached to provide object’s identity. The RFID reader transmits a query signal to the tag and receives reflected signal from the tag, which in turn is passed to the database. The database connects to a processing center to identify objects based on the reflected signals within a (10 cm to 200 m) range. RFID tags can be active, passive or semi-passive/active. Active tags are powered by battery while passive ones do not need battery. Semi-passive/active tags use board power when needed. The NFC protocol works at high frequency band at 13.56MHz and supports data rate up to 424 kbps. The applicable range is up to 10 cm where communication between active readers and passive tags or two active readers can occur. The UWB communication technology is designed to support communications within a low range coverage area using low energy and high bandwidth whose applications to connect sensors have been increased recently. Another communication technology is WiFi that uses radio waves to exchange data amongst things within 100 m range. WiFi allows smart devices to communicate and exchange information without using a router in some ad hoc configurations. Bluetooth presents a communication technology that is used to exchange data between devices over short distances using short-wavelength radio to minimize power consumption. Recently, the Bluetooth special interest group (SIG) produced Bluetooth 4.1 that provides Bluetooth Low Energy as well as high-speed and IP connectivity to support IoT. The IEEE 802.15.4 standard specifies both a physical layer and a medium access control for low power wireless networks targeting reliable and scalable communications. LTE (Long-Term Evolution) is originally a standard wireless communication for high-speed data transfer between mobile phones based on GSM/UMTS network technologies. It can cover fast-travelling devices and provide multicasting and broadcasting services. LTE-A (LTE Advanced) is an improved version of LTE including bandwidth extension which supports up to 100 MHz, downlink and uplink spatial multiplexing, extended coverage, higher throughput and lower latencies. D. Computation Processing units (e.g., microcontrollers, microprocessors, SOCs, FPGAs) and software applications represent the “brain” and the computational ability of the IoT. Various hardware platforms were developed to run IoT applications such as Arduino, UDOO, FriendlyARM, Intel Galileo, Raspberry PI, Gadgeteer, BeagleBone, Cubieboard,Z1,WiSense, Mulle, and T-Mote Sky. Furthermore,many software platforms are utilized to provide IoT functionalities. Among these platforms, Operating Systems are vital since they run for the whole activation time of a device. There are severalReal-Time Operating Systems (RTOS) that are good candidates for the development ofRTOS-based IoT applications. For instance, the Contiki RTOS has been used widely in IoT scenarios. Contiki has a simulator called Cooja which allows researcher and developers to simulate and emulate IoT and wireless sensor network (WSN) applications [36]. TinyOS [37], LiteOS [38] and Riot OS [39] also offer light weight OS designed for IoT environments. Moreover, some auto industry leaders with Google established the Open Auto Alliance (OAA) and are planning to bring new features to the Android platform to accelerate the adoption of the Internet of Vehicles (IoV) paradigm [40]. Some features of these operating systems are compared in Table I. Cloud Platforms form another important computational part of the IoT. These platforms provide facilities for smart objects to send their data to the cloud, for big data to be processed in real-time, and eventually for end-users to benefit from the knowledge extracted from the collected big data. There are a lot of free and commercial cloud platforms and frameworks available to host IoT services. Some of these services are introduced in Section VII-B.
- Devices use protocols like Bluetooth, Z-Wave, or ZigBee to establish direct device-to-device communications It allows devices to adhere to a particular communication protocol to communicate and exchange messages to achieve their function commonly used in applications like home automation systems Devices usually have built-in security and trust mechanisms (Device-specific data models require redundant development efforts by device manufacturers). Underlying device-to-device communication protocols are not compatible, forcing the user to select a family of devices that employ a common protocol.
- IoT device is directly connected to an Internet cloud service using existing communications mechanisms like IP network. Enables the user to obtain remote access to their devices and their software updates. This model adds value to the end user by extending the capabilities of the device beyond its native features. Interoperability challenges can arise when attempting to integrate devices made by different manufacturers. “vendor lock-in’’ - If proprietary data protocols are the user may be tied to a specific cloud service, limiting or preventing the use of alternative service providers.
- Also known as device-to-application-layer gateway (ALG) model IoT device connects through an ALG service as a conduit to reach a cloud service. Application software operating on a local gateway device, which acts as an intermediary between the device and the cloud service and provides security and other functionality such as data or protocol translation. Several forms of this model are found Smartphone App e.g. personal fitness trackers SmartThings hub devices e.g. Home automation applications. Can also bridge the interoperability gap between devices themselves. Frequently used to integrate new smart devices into a legacy system with devices that are not natively interoperable with them. The development of the ALG software and system adds complexity and cost to the overall system. It is expected that in the future, more generic gateways will be deployed to lower cost and infrastructure complexity for end consumers, enterprises, and industrial environments.
- CoAP-Constrained Application Protocol JSON-JAVA SCRIPT OBJECT NOTATION users to export and analyze smart object data from a cloud service in combination with data from other sources. This approach is an extension of the single device-to-cloud communication model, which can lead to data silos where “IoT devices upload data only to a single application service provider’’. A back-end sharing architecture allows the data collected from single IoT device data streams to be aggregated and analyzed. Effective back-end data-sharing architectures allow users to move their data when they switch between IoT services, breaking down traditional data silo barriers. This architecture model is an approach to achieve interoperability among these back-end systems. As the IETF Journal suggests, “Standard protocols can help but are not sufficient to eliminate data silos because common information models are needed between the vendors.”
- The IoT ecosystem is composed of a variety of business players. Each business player plays at least one business role, but more roles are possible. The identified IoT business roles are shown in Figure. Device provider: The device provider is responsible for devices providing raw data and/or content to the network provider and application provider according to the service logic. Network provider: The network provider plays a central role in the IoT ecosystem. In particular, the network provider performs the following main functions: access and integration of resources provided by other providers; support and control of the IoT capabilities infrastructure; offering of IoT capabilities, including network capabilities and resource exposure to other providers. Platform provider:The platform provider provides integration capabilities and open interfaces. Different platforms can provide different capabilities to application providers. Platform capabilities include typical integration capabilities, as well as data storage, data processing or device management. Support for different types of IoT applications is also possible. Application provider:The application provider utilizes capabilities or resources provided by the network provider, device provider and platform provider, in order to provide IoT applications to application customers. Application customer:The application customer is the user of IoT application(s) provided by the application provider.

- The IoT adds the dimension "Any THING communication" to the information and communication technologies (ICTs) which already provide "any TIME" and "any PLACE" communication. “Things” are objects of the physical world (physical things) or of the information world (virtual world) which are capable of being identified and integrated into communication networks. Things have associated information, which can be static and dynamic. Physical things exist in the physical world and are capable of being sensed, actuated and connected. E.g. surrounding environment, industrial robots, goods and electrical equipment. Virtual things exist in the information world and are capable of being stored, processed and accessed. Examples of virtual things include multimedia content and application software.

- Network Connectivity Key aspects when considering network connectivity: • Range - are you deploying to a single office floor or an entire city? • Data Rate - how much bandwidth do you require? How often does your data change? • Power - is your sensor running on mains or battery? • Frequency - have you considered channel blocking and signal interference? • Security - will your sensors be supporting mission critical applications?
- type of access required will depend on the nature of the application. SIGFOX and LoRa, have been developed and designed solely for machine-type communication (MTC) applications addressing the ultra-low-end sensor segment, with very limited demands on throughput, reliability or QoS.
- eMTC – delivering further LTE enhancements for Machine Type Communications, building on the work that started in Release-12 (UE Cat 0, new power saving mode) NB-IOT - a new radio added to the LTE platform, optimized for the low end of the market EC-GSM-IoT – bringing EGPRS enhancements, which in combination with Power Save Mode (PSM) makes GSM/EDGE systems IoT ready.
