On Developing a New 5G Spectrum Usage Fee Model for Indonesia

This paper reports on the development of the 5G spectrum usage fee in Indonesia. The fee was first applied in 2010 to charge mobile network operators (MNOs) that provided cellular services. However, cellular technologies have improved rapidly from 2G, 3G, 4G to 5G, and many modern innovative cellular services demand larger spectrum bandwidth. Therefore, the existing spectrum usage fee must be revised to meet the needs of the community better and to improve the efficiency and effectiveness of spectrum use. This study modifies the characteristics of the existing cost structure of the Indonesian spectrum usage fee, designing and proposing a new 5G spectrum usage fee model to support 5G technology usage scenarios and maximize the benefits of the mid-band (3.5 GHz), mmWave, or high band radio frequencies (26 GHz and 28 GHz). The new spectrum usage fee model includes spectrum-sharing parameters (non-orthogonal spectrum-sharing and orthogonal spectrum sharing) and private network to optimize the use of the available spectrum because the new proposing formula does not use the nationwide population, but instead, it uses the population within a specific area with both human and non-human (machine) populations. This new model is expected to help regulators prepare 5G technology regulations for application in Indonesia

Ship Speed Estimation using Wireless Sensor Networks: Three and Five Sensors Formulation

Intrusion detection on the sea is an important surveillance problem for harbor protection, border security, and commercial facilities such as oil platforms, fisheries facilities and other marine wealth. Widely used methods for ship detection are using radar or satellite which is very expensive. Besides the high cost, the satellite image is easy affected by the cloud. And it is difficult to detect small boats or ships on the sea with marine radar due to the noise or clutters generated by the uneven sea surface. In this paper, we propose ship speed estimation by taking advantage of ship-generated wave’s characteristics with Wireless Sensor Network (WSN). We use a grid fashion for sensor node deployment that can be clustered into three and five sensors. We propose the ship speed formulation for each type of claster. We use three sensors, we may expect to improve energy efficiency by involving small number of sensor for detection. We use five sensors, we may expect to improve accuracy of detection. We also propose an algorithm for detection by incorporating individual sensor detection. The individual sensor detection produces a time stamp that records the ship-generated waves intruding the sensors

A Novel Session Key Update Scheme for LoRaWAN

This paper proposes a novel Long-range Wide Area Network (LoRaWAN) session key updating scheme to enhance the security of LoRaWAN with cost-effective communication that provides a unique key for each communication session. The scheme consists of three sequential stages, i.e., initialization, keying material preparation, and key updating, on the basis of the truncated Photon-256 algorithm with updatable keying materials. These stages are structured by a set of novel communication protocols. To prove the uniqueness of the key, we validated its sequence bit randomness using the NIST 800-22 and ENT statistical test suites. The validation results show that the key passes all test parameters. Subsequently, the communication protocols were validated by using Scyther tools. We proved that these protocols ensure the security of the LoRaWAN key update scheme and guarantee that active interception does not occur. The analysis was performed by focusing on the security features of data confidentiality, integrity protection, mutual authentication, perfect forward secrecy, and replay attack resistance. Finally, a formal security analysis using GNY logic indicated that the overall security goals are achieved. The proposed scheme’s performance was evaluated in terms of computational cost, communication cost, and storage. The computational cost needed by the scheme is very small, indicating that there is no additional burden on the backend system. The communication cost requires less traffic than previous solutions, yet it offers more robust security for LoRaWAN by producing a new key in every communication session. The scheme needs insignificant additional storage that is considered negligible

Optimizing Search and Rescue Personnel Allocation in Disaster Emergency Response using Fuzzy Logic

Several models have been developed to facilitate decision-making in disaster management, especially in relation to emergency resource allocations. These models are required in order for search and rescue personnel to operate efficiently. However, in Indonesia, in general, technology has not been used to help make decisions during the response phase; rather, these decisions are still made subjectively. This paper presents a decision-making model that helps search and rescue teams determine the number of personnel to deploy. Therefore, it streamlines the allocation of personnel in a search area, and it determines the number of personnel that are needed based on the area, population density, equipment, and the number of high buildings. Then, those variables are processed using a fuzzy expert system and a decision tree. The data and knowledge acquired as a reference were obtained from disaster management experts as well as experienced practitioners in the field of Search and Rescue
