“…Moreover, a partition form games (PFG) approach in SDN-based intercloud architecture is adopted for capacity management and load balancing. Similarly, Ruia et al 109 addresses the problem of increased workload on the controller as the routers and switches generate frequent requests. The author presented a flow cache as a software-based cache for temporarily storing the contents of the recent flow table entries installed on the switches.…”

The need to provide services closer to the end-user proximity leads to the exchange of a large volume of data generated from the smart devices deployed at different geo-distributed sites. The massive amount of data generated from the smart devices need to be transmitted, analyzed, and processed. This requires seamless data exchanges among geo-separated nodes, which results in a considerable burden on the underlying network infrastructure and can degrade the performance of any implemented solution. Therefore, a dynamic, agile, and programmable network management paradigm is required. To handle the challenges mentioned above, software-defined networking (SDN) gained much attention from academia, researchers, and industrial sectors.Shifting the computational load from forwarding devices to a logically centralized controller is a dream of every network operator who wants to have complete control and global visibility of the network. Also, the concept of network functions virtualization (NFV) in SDN controller is required to increase resource utilization efficiency. Thus, in this paper, a comprehensive survey on SDN for various smart applications is presented. This survey covers the infrastructural details of SDN hardware and OpenFlow switches, controllers, simulation tools, programming languages, open issues, and challenges in SDN implementation with advanced technologies such as 5G and microservices. In addition, the challenges on the control plane and data plane are highlighted in detail, such as fault tolerance, routing, scheduling of flows, and energy consumption on OpenFlow switches. Finally, various open issues and challenges future scope of SDN are discussed and analyzed in the proposal.

“…Caching is one of the promising technology for speed up data retrieval time, reduces the number of path lengths, and improves system efficiency. Caching strategies exploit storage capacity to absorb traffic by replicating the most popular content closer to the node and enable low processing cost and remove a single point-of-failure [8][9][10]. Therefore, the integration of caching in fog computing will enable fog nodes to identify the demand of the user and pro-actively select the most suitable contents to cache in geo-distributed nodes and improve the resource utilization.…”

Fog computing is a promising technique to reduce the latency and power consumption issues of the Internet of Thing (IoT) ecosystem by enabling storage and computational resource close to the enduser devices with additional benefits such as improved execution time and processing. However, with an increase in IoT devices, the resource allocation and job scheduling become a complicated and cumbersome task due to limited and heterogeneous resources along with the locality restriction in such computing environment. Therefore, this paper proposes a Cache-based Approach (CBA) for efficient resource allocation in fog computing environment, while maintaining the quality of service. The proposed algorithm is realized using iFogSim simulator and a comprehensive comparison is presented with the traditional First Come First Served and Shortest Job First policies. The performance evaluation revealed that with the proposed scheme the execution time, latency, processing delays and power consumption decreased by 38%, 11.1%, 6% and 17.8%, respectively as compared to the traditional schemes.

“…During the initial authentication, the controller will cache the relevant information. The idea of using cache in SDN has been investigated in few studies [146] [147], we enhance the concept to leverage its use for authentication purposes thus aiding in latency reduction. The problem of privacy, non-tractability and non-link ability are solved by using a pseudonym for the entities involved in the procedure.…”

Quality of service (QoS) mechanisms deal with ensuring the high quality services offered by network. Reliability, accessibility and security are some of the main features of any service offered by a network. Support for diverse QoS requirements is one of the key areas of interest in the Long Term Evolution (LTE) and LTE-Advanced based networks. Carrier Aggregation (CA), in which the bandwidth is aggregated across different bands to achieve a higher bandwidth, is one of the most significant among them. Dual Connectivity (DC), Coordinated Multipoint Transmission (CoMP), Device-to-Device Communications (D2D), and Self-Organizing Networks (SON) are some of the other leading technologies introduced in LTE-Advanced. Because of the introduction of these new technologies, existing QoS and security mechanisms in LTE cannot be mapped directly to LTE-Advanced, so there is a need to investigate and develop new mechanisms for LTE-Advanced. The aim of this research is to develop QoS and security provisioning mechanisms for LTE-Advanced based 4G/5G networks The CA technology has introduced new challenges for LTE-Advanced resource matching. Radio Resources Management (RRM) is one of the key elements for QoS provisioning. We have developed a new RRM technique utilizing game theory. Matching Markets are known to solve different resource-matching problems, such as kidney exchange, child adoption, matching doctors, and college admission. We model the problem of resource allocation as a matching game and propose a solution utilizing game theory, which takes into consideration the QoS demand of the users. The allocation is done based on channel conditions, QoS profiles, and carrier selection. The proposed Matching Game (MG) algorithm finds a stable Pareto efficient matching of resource blocks to users. Theoretical i I would like to thank my supervisor, Dr. Maode Ma for his invaluable advice and guidance during this research. His encouragement has helped me to overcome many difficulties during the research. I am also thankful to my family. It would not have been possible without their support. To my parents who have always encouraged and supported me in my pursuits. To my beloved wife Ainee for her unwavering support.
