Full textImproving access and quality of public health services in Indonesia is still a big challenge. Geographic obstacles, shortage, and maldistribution of specialist/doctors especially in rural areas are some of the challenges to be answered. In 2016, the city council of Makassar Indonesia has developed a telemedicine system called "home care" to overcome those challenges. They created mobile healthcare vehicle called "Dottoro ta" that gives healthcare services 24 hours/day to the community. This vehicle is equipped with ElectroCardioGraphy (ECG), UltraSonoGraphy (USG) and other standard medical equipment. When patients call this service, a team consisting of doctors, nurses and drivers will move to the patient's location and gives a proper treatment. Meanwhile, the development of Internet of Things (IoT) technologies offers a broad opportunity to improve these services. Changing this equipment with IoT devices will offer a lot of advantages. IoT is the recent technological term, which is a collection of devices or sensors that have connectivity to the internet. Here, the Internet does not have to be a global connection; indeed, a Local Area Network (LAN) is also possible as long as it supports TCP/IP protocols. Most IoT devices use wireless connections to ensure mobility and portability. However, wireless devices have some fundamental issues such as energy consumption, noise and interference of wireless communication. IoT has many variations for implementation including healthcare sectors. Today, sensor nodes have changed into small, unobtrusive and powerful devices, which can be easily accommodated into wearable devices such as smart watches, bracelets, gloves or buttons. Thus, it gives more convenient way to collect the health condition data of patients using wearable sensors and then send, analyzed and stored the data in the cloud. For example, by using heart rate sensors, the conditions of the patients such as heart attacks, anxiety and stress can be continuously monitored. Another potential of using IoT on health sectors is telemedicine field, enabling doctors/nurses to perform retrieval of data in real-time and immediately perform diagnostics on the spot, without preoccupied with the installation of conventional medical devices. This will speed up diagnosis and give a positive impact on the health of the patient. Indeed, deploying IoT system in the health sector has several advantages over conventional wired systems such as ease of use, reducing the risk of infection, reducing the risk of failure, reducing user discomfort, increasing mobility, improving the efficiency of hospital care, and lower installation costs. However, providing the robust transmission in the wireless communication is a challenge in the healthcare domain, because continuous updated health data is very important for the treatment of the patients. In this research activity, we propose a new cross layer protocol to overcome this problem. The proposal takes advantages of beacon power measurements in the node’s PHY layer to determine whether there is interference from the human body or not. This information is used by the MAC layer to decide the transmission of packets. Our results show that there are significant improvements of the PER while maintaining the throughput relatively the same as the conventional protocol. We analytically show the effect of body pathloss on 802.11ah network and its effects in terms of power consumption for the healthcare sensors. We compare the standard pathloss of 802.11ah with body pathloss. We see that body pathloss increase PER and decrease throughput because the body absorbs the electromagnetic signal. We also propose a novel cross-layer algorithm to counter the effect of body pathloss. The idea is to defer the data transmission if there is a high probability of body pathloss by detecting the received power of beacon

Full textThe realm of intelligent transportation hinges upon robust vehicular communication infrastructure, vital for traffic management, road monitoring, Internet of Things (IoT) accessibility, and driver/passenger information. While the conventional IEEE802.11p standard has long dominated this domain, the advent of 5G and its successors marks a paradigm shift.This thesis represents a comprehensive exploration of 5G and beyond technologies specifically tailored to the unique demands of Vehicle-to-Everything (V2X) communication. The primary aim is a meticulous analysis of Non-Orthogonal Multiple Access (NOMA) technology and Multi-Carrier Modulation (MCM) schemes within the context of next-generation V2X applications. Central to this exploration is the pursuit of cross-layer PHY/MAC (Physical Layer/Medium Access Control) design strategies aimed at elevating performance benchmarks.The research journey begins with an introductory overview, delving into the historical context and relevance of V2X communications, accompanied by an examination of the diverse requirements across V2X use case groups. This foundational groundwork combines insights from normative organizations and the latest literature, providing a comprehensive overview of the historical landscape of vehicular communication.Subsequently, the thesis navigates the contemporary landscape, emphasizing the application of 5G enabling technologies to various V2X use cases. It maps the relationship between V2X Use Case Groups and Enabling Technologies while exploring the Hierarchical 5G V2X high-level architecture. This exploration bridges current communication requirements and existing standards with open research directions and impending challenges.The core of the thesis revolves around the exploration of NOMA and MCM schemes' implications within next-generation V2X applications. The culmination of this research manifests in a cross-layer design paradigm focusing on the enhancement of performance and adaptability within cellular vehicle-to-everything (C-V2X) communication systems. By dissecting NOMA mechanisms within the Physical/Medium Access Control (PHY/MAC) layers, this study demonstrates substantial throughput performance improvements compared to conventional Orthogonal Multiple Access (OMA) systems.The outcomes of this thesis aspire to contribute advanced solutions for future autonomous and connected transport systems, with a specific emphasis on the enhancement of physical and medium access layer performance within sophisticated V2X scenarios
