With each passing day, the information and communication technologies are evolving with more and more information shared across the globe using the internet superhighway. The threats to information, while connected to the cyber world are getting more targeted, voluminous, and sophisticated requiring new antifragile and resilient network security mechanisms. Whether the information is being processed in the application, in transit within the network or residing in the storage, it is equally susceptible to attack at every level of abstraction and cannot be handled in isolation as the case has been with conventional security mechanisms. The advent of Software-Defined Networks (SDN) has given a new outlook to information protection, where the network can aid in the design of a system that is secure and dependable in case of cyber threats. The nature of SDN, mainly its programmability and centrality of network information and control has led us to think of security in an antifragile perspective. Our networks can now thrive and grow stronger when they are exposed to volatility by overwhelming cyber threats. However, SDN infrastructure itself is susceptible to severe threats that may mutilate the provision of its usability as security provider. Both these perspectives of “Security with SDN” and “Security for SDN” have invited research and innovations, yet both these approaches remain disintegrated, failing to support each other. The contribution of this paper is threefold, with first reviewing the current state of the art work for both perspectives of SDN security. Second, it advocates the necessity and introduces a novel approach of antifragile cyber security within SDN paradigm and finally it proposes a unified model for integrating both approaches of “Security with SDN” and “Security for SDN” to achieve the overall objective of protecting our information from cyber threats in this globally connected internetwork.

Vehicular Ad Hoc Networks (VANETs) are getting more popularity due to the potential Intelligent Transport Systems (ITS) technology. It provides many efficient network services such as safety warnings (collision warning), entertainment (video and voice), maps based guidance, and emergency information. VANETs most commonly use Road Side Units (RSUs) and Vehicle-to-Vehicle (V2V) referred to as Vehicle-to-Infrastructure (V2I) mode for data accessing. IEEE 802.11p standard which was originally designed for Wireless Local Area Networks (WLANs) is modified to address such type of communication. However, IEEE 802.11p uses Distributed Coordination Function (DCF) for communication between wireless nodes. Therefore, it does not perform well for high mobility networks such as VANETs. Moreover, in RSU mode timely provision of data/services under high density of vehicles is challenging. In this paper, we propose a RSU-based efficient channel access scheme for VANETs under high traffic and mobility. In the proposed scheme, the contention window is dynamically varied according to the times (deadlines) the vehicles are going to leave the RSU range. The vehicles with shorter time deadlines are served first and vice versa. Simulation is performed by using the Network Simulator (NS-3) v. 3.6. The simulation results show that the proposed scheme performs better in terms of throughput, backoff rate, RSU response time, and fairness.

Cloud computing has become one of the most dynamic and adoptable computing paradigms. Multimedia Cloud Computing (MCC) is one of today’s hot research topic. MCC is proven to be a most dynamic and efficient platform for managing a large amount of multimedia contents with maximum deployment of computing and processing resources at the service provider instead of users. Resilience and dependability are two key constituents to assure the reliability and availability of any service in the presence of errors and system failures. The heterogeneous environment of MCC has given rise to various challenges related to resource allocation and task management. Antifragility is a key to such environments, to let the disorder drive the strength of these systems. This paper is mainly divided into three parts. The first part discusses in detail the available state-of-the-art related to resource management under MCC. Similarly, the second part presents the comprehensive literature review on the task management in MCC. The third part presents the critical analysis and open research issues in MCC which help the researcher to define their research objectives in the field of MCC.

Usability is a vital aspect of the machine interface. When users do not access the features of a machine, the features do not serve the design purpose. When a user confronts a different machine interface from his prior experiences, the learning process takes tremendous time and incurs cognitive stresses to the user. Smart phones, one of the most popular machines recently, share many common features regardless of vendors, but users find it very hard to switch them. It requires different clicks or touches to operate an application in one system and another. This paper focuses on evaluating the elements of smart phone systems, in terms of learnability and usability, such as Users, Tasks, Content, Context, Experience and Perception of users through survey. Then we conduct the task analysis for participants to evaluate the usability among users over the sampled smart phones of 3 latest brands. Our result shows that usability is a serious threat to the effectiveness of smart phones since 47% of the youth do not use smart phones at all, 31.5% of the users have accessibility threat for accessing its features and 45.5% of the users have usability threat. Overall just 23% of the users have fully adopted the features of smart phones.

Delivery of multimedia content over network has always been given vital importance since its inception. Different models for content delivery have been proposed with respect to multiple factors like bandwidth, quality of content, importance, and delivery method, etc. In this paper, we propose a Hyper Text Transfer Protocol-based rate adaptive transcoding and streaming technique that maintains its multimedia streaming quality, especially when network grows congested and fragile during Disaster Management and Recovery operations. The proposed solution provides users high-quality audio and video contents even when network resources are limited and fragile. We developed a real-time test bed that can deliver high-quality streaming videos by transcoding the original video in real time to a scalable codec, which allows streaming adaptation according to network dynamics. We also performed validation tests to ensure multimedia delivery in cloud computing, functionality on our hosted website for live communication between transmitter and receiver. From our experiments, we observed that the rate adaptive transcoding and streaming can efficiently deliver information services such as live multimedia in emergency and disasters under very low bandwidth environments.

Making machines for visually impaired persons is very challenging because they do not receive any useful information through SIGHT. The perception of background activities can be a good supportive mechanism for visually impaired users. In this work we focus on ATMs and propose a new ATM design, i.e., skill specific spoken dialogues based ATM (3s ATM). The personalized ATM design fulfills the requirements of visually impaired people while provisioning services for normal users also. Our proposed ATM is designed to assimilate into conventional ATMs and enable the effective interaction of visually impaired users with the machine. We first analyze the conventional ATM system through heuristics index to simulate its standardized design. For peer evaluation, visually impaired participants carry out the task analysis for simulated systems, i.e., both conventional ATM and 3s ATM. We found that 3s ATM design achieves 47% higher learnablility and 76% better usability than conventional ATMs. Thus we can achieve the machine compliance by overlooking the barriers and needs of the visually impaired persons in design stage.

Discrete math has countless applications in computer science. This paper also identifies another application in computer networks by developing the possible sequences of interaction among nodes from different platforms. The mobile nodes scattered across the network need to communicate and exchange messages either directly or through servers. The more dynamic the mobile nodes, the more diffusion or high turnover of nodes leaving and entering different servers or platforms and hence, higher the overhead. This paper proposed an algorithm that indicates and predicts the overhead in different scenarios of grouping of nodes under different servers. On the basis of this prediction and information about the geographical distribution, the nodes can foresee and arrange for resources or the requisites for establishing communication sessions among nodes of different servers.

With the increasing demand for over the top media content, understanding user perception and Quality of Experience (QoE) estimation have become a major business necessity for service providers. Online video broadcasting is a multifaceted procedure and calculation of performance for the components that build up a streaming platform requires an overall understanding of the Content Delivery Network as a service (CDNaaS) concept. Therefore, to evaluate delivery quality and predicting user perception while considering NFV (Network Function Virtualization) and limited cloud resources, a relationship between these concepts is required. In this paper, a generalized mathematical model to calculate the success rate of different tiers of online video delivery system is presented. Furthermore, an algorithm that indicates the correct moment to switch between CDNs is provided to improve throughput efficiency while maintaining QoE and keeping the cloud hosting costs as lowest possible.

Twenty‐first century global job market competition requires Science, Technology, Engineering, and Mathematics (STEM) university curricula to support both state‐of‐the‐art technical and soft skills learning to improve graduate employment. This necessitates the transformation of the current teaching and learning methodology powered by a social and collaborative platform to provide a social co‐learning environment. This social co‐learning will provide students with opportunities for self‐enrichment while supporting their technical skills and hands‐on needs. The platform must also provide the required lab infrastructure for hands‐on experimentation. This paper proposes the design and implementation of a cloud based platform called Edu‐Cloud. The Edu‐Cloud has been designed to provide automated resource provisioning and perform on‐the‐fly deployment of scalable virtual network functions to stream multimedia content closer to the global learners. This would help to meet the specific learning needs of a group of global interconnected students with similar learning skills and abilities. The benchmarking performance results show that the proposed framework works efficiently while reducing primary network traffic by deploying resources closer to the users and support scalability for a global deployment scenario.
