Satellite Communications Supporting Internet of Remote Things

Abstract

This paper focuses on the use of satellite communication systems for the support of Internet of Things (IoT). We refer to the IoT paradigm as the means to collect data from sensors or RFID and to send control messages to actuators. In many application scenarios, sensors and actuators are distributed over a very wide area, in some cases they are located in remote areas where they are not served by terrestrial access networks and, as a consequence, the use of satellite communication systems becomes of paramount importance for the Internet of Remote Things (IoRT). The enabling factors of IoRT through satellite are: 1) the interoperability between satellite systems and sensors/actuators; 2) the support of IPv6 over satellite. Furthermore, radio resource management algorithms are required to enhance the efficiency of IoT over satellite. In this work we provide an integrated view of satellitebased IoT, handling this topic as a jigsaw puzzle where the pieces to be assembled are represented by the following topics: MAC protocols for satellite routed sensor networks, efficient IPv6 support, heterogeneous networks interoperability, quality of service management, group-based communications. Index Terms-Internet of Remote Things (IoRT), Internet of Things (IoT), Machine to Machine (M2M) communications, satellite communications, Wireless Sensor and Actuator Networks (WSAN).

A Review on Inter-Satellite Optical Wireless Communication

“…5) Reducing Antenna Size: The size requirement of the transmitter and receiver antenna is very large and also bulky if RF/Microwave system is to be active. But in optical intersatellite communication, the antenna size gets reduced to centimeters only, as its carrier frequency is very large, therefore, decreasing the heaviness of the satellite and also reducing power requirement for the communication system [60][61]. The cost of the satellite is also greatly reduced by decreasing the size and height of payloads of the satellite.…”

Usability Evaluation Criteria for Internet of Things

“…Healthcare: Th is is an important domain in which the IoT actively enhances productivity and improves service delivery [5], [18]- [20]. It provides a systematic mechanis m in wh ich track records of human health can be analyzed, monitored and also provide emergency services to individuals in need as a result of actively tracking the health activity of the individual.…”

“…Research in [7]- [8] and [18]- [20] suggest that the IoT is co mposed of four funda mental layers: perception, network, middleware and application, as described below:…”

“…According to [5]- [6], [19]- [20] and [22], the fo llo wing are the essential co mponents that make the IoT paradig m a possibility: [52] This technological component is characterized as one of the enabling co mponents of the IoT, as described in [11]. It allows fo r autonomous identification of objects (things) as well as data capture of fundamental informat ion about the objects through radio waves, tags and a reader.…”

“…impaired v ision, hearing problems or limited motor skills) is high, one may be fo rced to come up with an interface design that supports accessibility tools. According to [20], the IoT should have unique features and diverse requirements , be time tolerant, have secure connections, good monitoring and low energy consumption. These service requirements ensure that the user utilizes the system's fu ll potential without disruption in service.…”
