Network devices have always been considered as configurable black boxes until the emergence of software-defined networking (SDN). SDN enables the networks to be programmed according to the user requirements; furthermore, it allows the network to be easily modified to suit transient demands. However, how do we program the network? SDN-compliant switches offer a low-level interface that makes programming error-prone. The controllers provide application programming interfaces, but still low-level, limited, and inflexible. High-level languages have the potential to be a better alternative to program the network. There exist several SDN programming languages implementing different sets of functionalities, and focusing on solving various issues. In face of all this diversity, no published paper outlines a pragmatic view allowing to compare the SDN languages. This paper presents a systematic survey of up-to-date OpenFlow-based SDN programming languages. Our approach relies on a taxonomy comprising all prominent features found in those languages. A detailed review of the existing works is carried out investigating the foundational parts of the languages with their contributions. Examples are discussed to illustrate the fundamental abstractions. Last, all gathered information is summarized, discussing the main ongoing research efforts and challenges. Future abstractions and features to be incorporated into the next generations of SDN programming languages are also considered.

A Survey on SDN Programming Languages: Toward a Taxonomy

Past government efforts in addressing power challenges in Nigeria have yielded little results despite huge investments made in the energy sector. For meaningful economic growth, the importance of a sustainable power system cannot be overemphasized. However, with worlds advocacy on climate change and carbon footprint emissions reduction, renewable energy alternatives will offer a better solution. In this regard, this paper proposes a power model that will serve as a compliment to the current distribution grid network called Solar Satellite. This can be adapted for powering banks, government institutions, IT DataCenter, etc. We present an in-depth discussion on the design framework of a generic Solar Power System. In particular, a comprehensive outline of the design steps, considerations as well as the implementation strategies is presented. To further facilitate our work, we used Electronics Development Institute as our study testbed. In this regard, MATLAB Simulink tool was used to characterize the initial phase of the proposed system in the context of current-voltage sensor outputs. Also, we presented the optimal Solar Cell block's parameters as well as the I-V characteristics at 25 0 C. This work observes that a hybrid grid system will save downtime scenarios in case of drops in solar irradiation.

A liquid dispenser is a system or a machine which is designed and capable of responding to an instruction or request made by the user in other to dispense a particular liquid. This paper developed a liquid dispenser leveraging microcontroller technology with added features that eliminates manual operation of the dispenser's pumps. This is achieved by the use of cup sensor in the control unit that automatically detects the presence of cups or other container. It also solve the issue of overflow of fluid due to loss of concentration by the introduction of electronic keypad which enables the users to input their desired quantity. The system code implementation was implemented with Assembly language via a notepad editor saved as .asm file. The saved file was compiled with an assembler (MIDI — 51) which generated three files; hex file, obj file and list file. The hex file was used for the simulation of the design in Proteus 7.7 professional and burning of the microcontroller for construction. The outcome at the end of the specified design period was a working prototype that was able to dispense a liquid if the user activates the button from the keypad. The results shows that cup sensor carries out its sensing functionality satisfactorily.

peak current obtained were in the range of 3.1 – 3.6 µA for HbA, 1.7 – 2.2 µA for HbAS, 1.2 – 1.6 µA for HbS and 2.5 – 3.00 µA for HbAC in the fixed range of concentrations of the haemoglobins. These values were used to identify the phenotypes of several haemoglobins successfully. The values of the peak current are sufficiently distinct to allow for rapid determination of these phenotypes. The method is simple and faster than the conventional electrophoretic method and removes the need to use standards once the characteristic values of peak current have been established. The good correlation between peak current and concentration also provides an accurate determination of the concentrations of haemoglobin samples.

There has been a growing spate of Cyber attacks targeted at different corporate enterprises and systems across the globe. The scope of these attacks spans from small scale (grid and control system manipulation, domestic meter cyber hacking etc) to large scale distributed denial of service attacks (DDoSA) in enterprise networks. The effect of hacking on control systems through distributed control systems (DCS) using communication protocols on vulnerable home area networks (HANs) and neighborhood area networks (NANs) is terrifying. To meet the current security requirements, a new security network is proposed called Smart grid convoluted network (SGCN). With SGCN, the basic activities of data processing, monitoring and query requests are implemented outside the grid using Fog computing layer-3 devices (gatekeepers). A cyber monitor agent that leverages a reliable end-to end-communication network to secure the systems components on the grid is employed. Cyber attacks which affects the computational requirements of SG applications is mitigated by using a Fourier predictive cyber monitor (FPCM). The network uses flexible resources with loopback services shared across the network. Serial parallelism and efficient bandwidth provisioning are used by the locally supported Fog nodes within the SG cloud space. For services differentiation, SGCN employed secure communication between its various micro-grids as well as its metering front-ends. With the simulated traffic payload extraction trend (STPET), SGCN promises hard time for hackers and malicious malwares. While the work guarantees security for SGs, reliability is still an open issue due to the complexity of SG architecture. In conclusion, the future of the Cyber security in SGs must employ the concept of Internet of Everything (IoE), Malware predictive analytics and Fog layers on existing SG prototypes for optimal security benefits.

Owing to large scale computing using the cloud, services can be provisioned with reliable QoS performance. Existing Campus Wireless Network Nigerian tertiary instutions have various challenges in terms of performance, ease of integration, and cost effectiveness. In this paper, a distinct classification of functional network models, their attributes and characteristics was highlighted. Research gaps were identified and a proposed autonomic web services architecture that manages both the performance of service users and the interconnection of WiMax-Wifi infrastructure into a service overlay network was discussed. This represents an intelligent Campus Wireless Network Architecture for services convergence. Low scale and medium scale computing networks were also discussed while outlining their issues. For the large scale computing network model, the advantages of the system include: easing of management tasks through the autonomic systems, ability to self-configure, self-optimizeze and self-heal. Efficient resource management, virtualization and WiMax connectivity interfaces are the core features. This research is still on-going but have developed a workable system for both service deployment and migration without overhauling the generic platforms in existing systems. In the long run, Nigerian instutions will benefit from the improved newtork resilience with improvement in overall performance.
