Management Issues

The current internet architecture cannot manage the massive data volumes produced by the smart IoT-based healthcare systems. Very recently, the idea of Software-Defined Networking (SDN) has surfaced to resolve the issues related to networking. The incorporation of SDN technology in IoT-based healthcare systems can possibly solve the existing quality of service and data management issues. Furthermore, the IoT-based healthcare system can attain enhanced Quality of Service (QoS) through the employment of such schemes that use shortest-path routing algorithms and offer higher bandwidth to lesser delay paths as per the QoS requirements. In this study, the SDN technology is integrated with IoT-based healthcare systems, and the delay is reduced for delay-sensitive applications by using the Bellman-Ford algorithm. The proposed scheme is deployed using the POX controller and can effectively handle the existing QoS issues in the IoT healthcare systems. The simulation results of the proposed scheme show a clear drop in delay values in comparison to the benchmark scheme.

Software Defined Networking (SDN) adalah teknologi baru yang dikembangkan untuk mengatasi masalah kompleksitas konfigurasi jaringan dengan pengelolaan lebih terpusat karena memisahkan antara control plane dan data plane. Penelitian ini menganalisis perbandingan performansi SDN menggunakan ryu controller dan pox controller. Protocol yang digunakan adalah protocol TCP dan UDP sedangkan routingnya menggunakan OSPF. Penerapan algoritma dijkstra dari perutean OSPF ke topologi fat tree pada SDN akan diukur unjuk kerjanya berdasarkan parameter Quality of Service yaitu delay, jitter, dan packet loss pada skenario tanpa background traffic. Transmisi data menggunakan traffic protocol TCP dengan RYU controller dan protokol UDP lebih baik karena memiliki delay sebesar 49.44% dan delay yang lebih stabil sebesar 0.01 %. Jitter yang dihasilkan adalah 27.59% lebih baik daripada POX controller sebesar 72.41% dan untuk protokol UDP menggunakan POX controller 99.97% sedangkan traffic protocol UDP menggunakan RYU controller lebih baik sebesar 0.03%. Packet loss dari kedua controller didapatkan hasil protokol TCP sangat bagus sebesar 0% sedangkan protokol UDP menggunakan POX controller 83.13%, menggunakan RYU controller 16.87%.

Growing organizations, institutions, and SMEs demand for transformation in all the aspects of their businesses along with the progression in time and technology. When it comes to healthcare, the growth should be heightened to higher levels with necessity. The need of providing quality of service (QoS) in healthcare is taking significant place, allowing health institutions and medical compliances to develop an ecosystem with cutting-edge technology with the same reliability but better productivity and performance. Moreover, the healthcare systems are aiming for a more patient-centric strategy. Healthcare systems work on complicated and traditional methods, oftentimes administered via teams of professionals who manage data and supportive mechanisms of the system. Blockchain could streamline and automate those methods, conserving weeks of effort in the company's production line to increase the overall revenue and discover new opportunities. This chapter aims to illustrate blockchain technology along with its state-of-the-art applications in healthcare.

Multiple Metrics

New web technologies have encouraged the deployment of various network applications that are rich with multimedia and real-time services. These services demand stringent requirements are defined through Quality of Service (QoS) parameters such as delay, jitter, loss, etc. To guarantee the delivery of these services QoS routing algorithms that deal with multiple metrics are needed. Unfortunately, QoS routing with multiple metrics is considered an NP-complete problem that cannot be solved by a simple algorithm. This paper proposes three source based QoS routing algorithms that find the optimal path from the service provider to the user that best satisfies the QoS requirements for a particular service. The three algorithms use the same filtering technique to prune all the paths that do not meet the requirements which solves the complexity of NP-complete problem. Next, each of the three algorithms integrates a different Multiple Criteria Decision Making method to select one of the paths that have resulted from the route filtering technique. The three decision making methods used are the Analytic Hierarchy Process (AHP), Multi-Attribute Utility Theory (MAUT), and Kepner-Tregoe KT. Results show that the algorithms find a path using multiple constraints with a high ability to handle multimedia and real-time applications.
