A Survey of IP Address for Next Generation Internet Services

This paper surveys the problem of the astronomical growing demand of Internet Systems participating in the public network which has led to the depletion of allocated Internet Protocol version 4.0 (IPV4) addresses. Already, four out of the Regional Internet Registry (RIR) namely: ARNIC, RIPE, LACNIC and ARPIN have exhausted their allocated IPV4 addresses while the fifth AFRICNIC (Africa’s RIR) is reportedly depleted. We also examine the limitations of IPV4, the features of IPV6 and different modes of operating IPV6 standard. Findings shows that the current population of the world is over 6billion people with a projection of 9billion people by the year 2050 and IPV6 can conveniently accommodate 2128 devices. This paper also proposes the migration from the present Internet Protocol version 4.0(IPV4) to a new Internet Protocol version 6.0(IPV6) addresses. This research work has shown that deploying the IPV6 could only be the possible solution to sustaining Internet Services globally.

Predicting Internet Bandwidth in Educational Institutions using Langrage’S Interpolation

This paper addresses the solution to the problem of Internet Bandwidth optimization and prediction in the institution of higher learning in Nigeria. The operation of the link-load balancer which provides an efficient cost-effective and easy-to-use solution to maximize utilization and availability of internet access is extensively discussed. This enables enterprises to lease for two or three ISP links connecting the internal network to the internet. The paper also proposes the application of the Langrage’s method of interpolation for the predictability of internet bandwidth in the institutions. The analysis provides a unique graphical solution of effective actual bandwidth (Mbps) and the corresponding acceptable number of internet Users (‘000) in the institutions. The prediction allows us to view the actual internet bandwidth and the acceptable number of internet Users as the population of users’ increases. Keywords: Internet Bandwidth, Optimization, Link-Load Balancer, Prediction, Maximized Utilization, Availability of Internet access

Implementation of Closed-circuit Television (CCTV) Using Wireless Internet Protocol (IP) Camera

This paper presents three techniques for configuring, interfacing and networking of a wireless IP-based camera for real-time security surveillance systems design. The three different real-time implementation techniques proposed for configuring, interfacing and networking the IP camera are: 1). accessing the IP-based camera using the WANSCAM or XXCAM vendor software, 2). accessing the IP-based camera via Firefox® web browser , and 3). accessing the IP camera via MATLAB with SIMULINK on an internet ready system. The live streaming video based on the proposed techniques can be adapted for image detection, recognition and tracking for real-time intelligent security surveillance systems design.  The paper also carried out a thorough comparative analysis of the three methods of achieving video streaming resulting from the output of the IP-based cameras. The analysis shows that the WANSCAM or XXCAM software displays the best video animations from the IP-based cameras when compared with the performance of the other methods.

Performance Analysis of NICs and Its Interactivity with Internet Services

This paper analyses the problem of slow data or video streaming on the World Wide Web internet through the network interface cards (NICs). The service of the entire network and internet connectivity largely rest on the installed Network Interface Cards (NICs). The performance of the various NICs such as 10Mbps, 100Mbps, 1,000Mbps and 10,000Mbps were examined using different message data sizes on the network. Also, the paper extensively discusses the performance of 10Gbps Ethernet card such as: data transmission time and throughput. The fact remained that the major backbone of the Internet network is the transmission control protocol (TCP) which is designed for reliable sending of data over the internet. The TCP as the protocol of the NIC is used for browsing web and downloading or uploading files. Additionally, the paper also examines the TCP feedback mechanism that is able to detect loss packets and retransmit them. Also, the TCP is able to dynamically adapt its packet sending rate to the network conditions in order to achieve the highest possible throughput. However, this paper proposes the use of the 10Gbps Ethernet card for the Internet Servers and Workstations for effective and fast internet access in all public networks. Keywords: Ethernet Card, Transmission Control Protocol, Data transmission time, throughput.

Performance Analysis of Grid-tied Sine-wave Inverters in a Hybrid Power System

The inverter performance model provides a new opportunity for accurately monitoring the performance and health of the inverter in real time. Grid-tied inverter monitoring can be accomplished by using a data acquisition system which provides a periodic measurement of dc voltage and power, as well as true ac power. In real time, inverter’s efficiency can be calculated empirically and compared to the inverter efficiency determined using the inverter performance model. Deviations between measured and calculated inverter efficiency would provide direct evidence of inverter malfunction or degradation in performance. It is likely, given experience, that the nature of the deviations would provide the diagnostic information needed to define required inverter maintenance for optimum future performance.
