Novel impairment-aware resource allocation scheme for elastic optical networks serving traffic with different service priorities Munasinghe, K.; Dharmaweera, M.N.; de Alwis, C. In this research paper, we propose a novel impairment-aware resource allocation scheme that increases spectrum efficiency of an elastic optical network (EON), while satisfying the quality of transmission (QoT) requirements of traffic connections with different service priorities (i.e., high and low priority traffic). To demonstrate the validity and superiority of our algorithm, we compared the results of our proposed resource allocation scheme against a benchmark algorithm. The results were simulated for a 6-node network and a 14-node network. Compared to the benchmark algorithm, on average, our proposed scheme increases spectrum efficiency by an additional 20 % while ensuring a minimum latency for high priority traffic, causing minimum disruptions to existing low priority traffic, and blocking less than 1 % of the total connections.

Efficient Medical Video Streaming by Pre Processing and Network Traffic Prioritization in Real-Time Balagalla, U.B.; Sivapatham, S.; Munasinghe, K.; Subasinghe, A.; de Alwis, C. Developing advanced healthcare applications to cater to the requirements of an ever-growing population has become one of the key areas of research in engineering. One major application in this area is medical video streaming, which is often used for remote monitoring of patients. Medical video streaming helps to overcome geographical barriers and offers medical services at the convenience of the patient. However, as medical videos carry critical and time-sensitive information, retaining the quality and reducing latency during transmission is paramount for accurate medical diagnosis. This paper presents the concept of effective medical video streaming, which incorporates novel methods in video pre-processing, video compression, and transmission of medical data over optical networks.

The Fight against the COVID-19 Pandemic with 5G Technologies Siriwardhana, Y.; de Alwis, C.; Ylianttila, M.; Liyanage, M. The COVID-19 pandemic has affected the world in an unexpected manner. The human race is battling against the pandemic while schools, universities, industries, hospitals and governments are seeking new methods and technologies to seamlessly continue their usual operations. In response, this paper presents how 5G and IoT (Internet of Things) related technologies can be efficiently utilized and developed to fight against the COVID-19 pandemic. Several use-cases on how 5G and IoT can be enablers to provide innovative solutions in the areas of telehealth, contact tracing, education, retail and supply chains, e-government/ remote office/ information sharing, smart manufacturing and factory automation, e-tourism and entertainment are presented along with their technical requirements and challenges. It is envisaged that the proposed solutions will be instrumental to facilitate the usual lifestyle, work and other dayto-day activities of humans in the post-pandemic world.
