MEC-enabled 5G Use Cases: A Survey on Security Vulnerabilities and Countermeasures

The future of mobile and internet technologies are manifesting advancements beyond the existing scope of science. The concepts of automated driving, augmented-reality, and machine-type-communication are quite sophisticated and require an elevation of the current mobile infrastructure for launching. The fifth-generation (5G) mobile technology serves as the solution, though it lacks a proximate networking infrastructure to satisfy the service guarantees. Multi-access Edge Computing (MEC) envisages such an edge computing platform. In this survey, we are revealing security vulnerabilities of key 5G-based use cases deployed in the MEC context. Probable security flows of each case are specified, while countermeasures are proposed for mitigating them.

Addressing Bandwidth-Driven Flow Allocationin RINA

Effective capacity allocation is essential for a network to operate properly, providing predictable quality of service guarantees and avoiding bottlenecks. Achieving capacity allocation fairness is a long-standing problem extensively researched in the frame of transport and network layer protocols such as TCP/IP. The Recursive InterNetwork Architecture offers programmable policies that enable more flexible control on the mechanics of network flow allocation. In this paper, we present our version of one of these policies, which provides flow allocation according to the bandwidth requirements of requesting applications. We implement the bandwidth-aware flow allocation policy by extending rlite, an open source RINA implementation. Our evaluation shows how the policy can prevent links from becoming oversaturated and use alternate paths to achieve high total link data-rate use.

Real-Time Dispatching of Large-Scale Ride-Sharing Systems: Integrating Optimization, Machine Learning, and Model Predictive Control

This paper considers the dispatching of large-scale real-time ride-sharing systems to address congestion issues faced by many cities. The goal is to serve all customers (service guarantees) with a small number of vehicles while minimizing waiting times under constraints on ride duration. This paper proposes an end-to-end approach that tightly integrates a state-of-the-art dispatching algorithm, a machine-learning model to predict zone-to-zone demand over time, and a model predictive control optimization to relocate idle vehicles. Experiments using historic taxi trips in New York City indicate that this integration decreases average waiting times by about 30% over all test cases and reaches close to 55% on the largest instances for high-demand zones.

Perlindungan Hukum dan Pemenuhan Hak Pekerja pada Program Jaminan Kesehatan Nasional

Badan Penyelenggara Jaminan Sosial (BPJS) berlaku pada tahun 2014, namun sampai saat ini masih banyak pemberi kerja dan pekerja yang kurang paham dengan program yang diselenggarakan BPJS Kesehatan, dan penerapannya masih belum dikategorikan optimal. Hal yang menarik dianalisis adalah Pertama, bentuk perlindungan pekerja dalam program Jaminan Kesehatan Nasional (JKN) dan Kedua, persoalan dalam penerapannya. Tulisan ini menggunakan jenis penelitian Yuridis Normatif dengan pendekatan perundang-undangan dan pendekatan analisis serta dianalisis secara normatif kualitatif. Dalam tulisan ini diketahui terdapat perubahan dari program Jaminan Sosial Tenaga Kerja (Jamsostek) ke BPJS kesehatan yang berimplikasi penerapan jaminan dan pelayanan kesehatan bagi pekerja. BPJS membuat prosedur yang dapat meningkatkan keterjangkauan peserta pekerja terhadap pelayanan kesehatan secara berjenjang dari fasilitas pelayanan Kesehatan (fasyankes) tingkat pertama ke tingkat lanjut. Terlepas dari hal tersebut, terdapat beberapa persoalan hukum dalam penerapan program JKN meliputi persoalan dari aspek kepesertaan, penggunaan kartu kesehatan dan jaminan pelayanan kesehatan. Social Security Administrative Bodies (referred as BPJS) established in 2014, but until now there are still many employers and workers who are not aware of the programs held by BPJS Kesehatan, moreover the implementation was still not optimal. The problems studied were first, the form of worker protection in the National Health Insurance program and second, legal issues in its implementation. This manuscript used Normative Juridical research with statute approach, analytical approach and qualitative analysis method. In this manuscript, it known that there is a change from the Workers’ Social Security program to BPJS Kesehatan which has implications for the implementation of health insurance and services for workers. After the enactment of the BPJS Law, there are protection scheme for health insurance for both formal and informal workers. In addition, the BPJS provides a mechanism that can increase the affordability of workers to tiered health services from the first level to the advanced level. Meanwhile, there are several obstacles in the implementation of the Social Security program which include constraints on the aspects of participation, use of health cards and health service guarantees.
