The Augmented Reality Service Provision in D2D Network

Abstract: This paper is dedicated to the augmented reality service provision by using of D2D communications. We consider the service which may be provided by using of local data source such as panoramic view video camera or any other. Local source provide information useful for nearest users. We propose using of multicast service. Our approach allows reach high users density users near the source. The aim of the paper is to determine an appropriate bitrate for the multicast stream on the base on the distribution of users in the service area.

Split-step Padé Approximations of the Helmholtz Equation for Radio Coverage Prediction over Irregular Terrain

Abstract: This paper is devoted to the numerical methods for the radio-wave propagation over the Earth’s surface. Split-step Pade rational approximations of the one-way Helmholtz equation are applied. The proposed formulation gives an opportunity to take into account the dielectric properties of the ground and vegetation. An arbitrary terrain profile can be modeled. An accurate truncation procedure is carried out by the non-local boundary conditions on the boundaries of the computational domain. Proposed approach provides a stable and fast numerical solution. The calculated results are compared with state-of-the-art propagation models and measured data.

Combating Counterfeit for IoT System Based on DOA

Abstract: There is no doubt that the IoT is a big revolution that has a great impact on our life. IoT provides the communication network for connecting physical objects (i.e. sensors and embedded systems). With the massive increase of IoT devices and the very high society impacts of the IoT including the wide range of applications predicted, the anti counterfeiting becomes an important issue. In this work, we mainly focus on this issue. DOA is a global system that enables the generation of digital objects with unique identifiers. Using DOA, we can identify any information and store it using a unique global identifier. We provide a framework for enabling and facilitating the use of DOA in IoT for anti counterfeiting. The system provides a unique identifier for each IoT device and enables the end user to check the device information and specifications through the identifi Moreover, the identifier can be used to identify the device the network. The user can extract the identifier of the device using a proper technology interface.

Method for Organizing Mesh Topology based on LoRa Technology

Abstract: Nowadays, Internet of Things (IoT) is one of the most current trends in the development of telecommunications. So many technologies have appeared with the aim of providing communication between the IoT devices. In this area, one of the newest technologies is LoRa, which represents the features of long-range transmission and energy savings. This article discusses the main characteristics of LoRa technology and based on which the method of organization mesh topology is proposed for the interaction of IoT devices. The proposed method is implemented on a complex hardware platform and the route search time depending on the number of nodes in the network is estimated.
