With rapid growth in popularity and use of Internet in academic institutions, the institutions are struggling to keep up with the demand. They need capability to effectively control, monitor and optimize the available bandwidth to ensure good service at optimum cost. This paper has described implementation of Coovachilli and free radius for management of internet bandwidth in academic institutions. During this research, freeware tools such as Freeradius and CoovaChilli have been used to manage Internet bandwidth on a per-user basis based on user credentials. The mechanisms have been used to control bandwidth of Wireless users. Same can be used for wired connections also. When a user tries to connect, the user is redirected to a captive portal under CoovaChilli. There the user provides login and password. Based on the credentials thus provided, CoovaChilli checks identity with the Freeradius. If authorized, the client is allowed access with the bandwidth as mentioned in the profile of the user in WISPr attributes define in Radreply table of Freeradius. When the user is not authorized, CoovaChilli sends an error message. This paper demonstrates that bandwidth can be effectively monitored, managed and optimized by using cost-effective open-source tools in the existing network scenario of the institution.

Attendance taking and maintaining is a tedious job in the academic institutions where the time of class is restricted. The manual attendance i.e., roll call or paper-based signature systems usually consumes more time and error prone and also possibility of recording proxy attendance is more. Attendance is one of the criteria in considering students’ eligibility for attending the external examinations and also for the promotion to the next semester / year, where these kinds of problems may cause severe effect on the academic institutions. As the strength of students in a class is increasing day by day; monitoring, awarding and maintenance of attendance has becoming a challenge for the academic institutions. As a solution, attendance can be recorded using anyone of the existing biometric techniques like fingerprinting, iris recognition, signature, face recognition etc. Face identification is the best method among all the earlier mentioned methods for implementing in the academic institutions as it does not require human intervention and it is a cost-effective technique. A novel student attendance recording and management system using a MATLAB application, LabVIEW, Camera interface and GSM is proposed in this paper. Students’ faces will be captured with the help of a camera connected to a computer and Eigen values of the captured images will be detected with the help of MATLAB executed by LabVIEW Mathscript node. LabVIEW, a graphical programming environment is adopted for acquiring face, processing and authenticating the student once the match is found. Authenticated student attendance will be updated, and a message will be sent with the help of GSM module interface to myRIO. Proposed system replaces the manual attendance system which improves the performance of existing system.

In the last decade, there is a rapid growth in the use of Internet by the organization for information sharing. As information is very vital to the organizations, it should be preserved and insulated from any unauthorized access or alternation. In last few years, attacks on the computer infrastructures have increased exponentially. Several information security techniques are available now a days like firewalls, anti-virus software and Intrusion prevention systems (IPSs), which are important tools for protecting an organization from intrusions. Now most attacks are impossible to defend with firewalls and anti-virus software alone. Without an IPS, such attacks are difficult to detect and prevent. This chapter presents different definitions of intrusion prevention system with meaningful explanation; compare network IPS with Host IPS, common and the advanced detection methods, common IPS components, coverage of attacks by IPS and criteria to select right IPS. Finally, this chapter concludes with an analysis of the challenges that still remain to be resolved.

Since the early 1980s, Open Source Software (OSS) has gained a strong interest and an increased acceptance in the software industry that has to date initiated a “paradigm shift” (O’Reilly, 2004). The Open Source paradigm has introduced wholly new means of software development and distribution, creating a significant impact on the evolution of numerous business processes. In this chapter we examine the impact of the open source paradigm in the e-Procurement evolution and identify a trend towards Open Source e-Procurement Application Frameworks (AFs) which enable the development of tailored e-Procurement Solutions. Anchored in this notion, we present an Open-Source e-Procurement AF with a two-phase generation procedure. The innovative aspect of the proposed model relates to the combination of the Model Driven Engineering (MDE) approach with the Service-Oriented Architecture (SOA) paradigm for enabling the cost-effective production of e-Procurement Solutions by facilitating integration, interoperability, easy maintenance, and management of possible changes in the European e-Procurement environment. The assessment process of the proposed AF and its resulting e-Procurement Solutions occurs in the context of G2B in the Western-Balkan European region. Our evaluation yields positive results and further enhancing opportunities for the proposed Open Source e-Procurement AF and its resulting e-Procurement Solutions.

Downstream Analysis

Field laboratories interested in using the MinION often need the internet to perform sample analysis. Thus, the lack of internet connectivity in resource-limited or remote locations renders downstream analysis problematic, resulting in a lack of sample identification in the field. Due to this dependency, field samples are generally transported back to the lab for analysis where internet availability for downstream analysis is available. These logistics problems and the time lost in sample characterization and identification, pose a significant problem for field scientists. To address this limitation, we have developed a stand-alone data analysis packet using open source tools developed by the Nanopore community that does not depend on internet availability. Like Oxford Nanopore Technologies’ (ONT) cloud-based What’s In My Pot (WIMP) software, we developed the offline MinION Detection Software (MINDS) based on the Centrifuge classification engine for rapid species identification. Several online bioinformatics applications have been developed surrounding ONT’s framework for analysis of long reads. We have developed and evaluated an offline real time classification application pipeline using open source tools developed by the Nanopore community that does not depend on internet availability. Our application has been tested on ATCC’s 20 strain even mix whole cell (ATCC MSA-2002) sample. Using the Rapid Sequencing Kit (SQK-RAD004), we were able to identify all 20 organisms at species level. The analysis was performed in 15 min using a Dell Precision 7720 laptop. Our offline downstream bioinformatics application provides a cost-effective option as well as quick turn-around time when analyzing samples in the field, thus enabling researchers to fully utilize ONT’s MinION portability, ease-of-use, and identification capability in remote locations.

Mapping Approach

Coastal areas harbor the most threatened ecosystems on Earth, and cost-effective ways to monitor and protect them are urgently needed, but they represent a challenge for habitat mapping and multi-temporal observations. The availability of open access, remotely sensed data with increasing spatial and spectral resolution is promising in this context. Thus, in a sector of the Mediterranean coast (Lazio region, Italy), we tested the strength of a phenology-based vegetation mapping approach and statistically compared results with previous studies, making use of open source products across all the processing chain. We identified five accurate land cover classes in three hierarchical levels, with good values of agreement with previous studies for the first and the second hierarchical level. The implemented procedure resulted as being effective for mapping a highly fragmented coastal dune system. This is encouraging to take advantage of the earth observation through remote sensing technology in an open source perspective, even at the fine scale of highly fragmented sand dunes landscapes.

Purpose – This paper aims to describe the design and business characteristics of the system pertaining to efficient and viable public services, the technical perspective and also usage results from the productive prototype. When the academic library of our institution turned to consider cost-effective solutions that would combine management and accounting for both printing and photocopying, it was realized that there are no open-source or enterprise platforms that can support such characteristics. Instead of relying on commercial solutions, the construction of a service was planned by means of integrating community-based projects and developing any missing components. Design/methodology/approach – The implementation of the system was based on the identification of appropriate open-source modules and on the development of ones that do not exist but are necessary to realize business procedures for credit reception, control and billing. Thus, the system integrates software for the management of printers and print tasks, for accounting for printing tasks, for user catalogues, for authentication modules and for the control of low level I/O operations. The aforementioned systems were integrated along with the following new modules that were developed to create a complete service. Findings – Our prototype has been operating at our University since May 2011. The system was installed at four sites in reading rooms of the library. Three of them are located in different departments within the University campus, while the fourth is located in the last reading room that has not yet moved within the campus. In two years, more than 28,000 pages were printed and charged. The steady rise in the number of served requests leads us to the conclusion that the system can cope with the heavy use of photocopying machines. Originality/value – The prototype described in this paper is a complete productive platform that is capable to accept money or credit over the counter or by using money receivers and provide billing and management for printing and photocopying. The system does not depend on any vendor technology, offers control, monitoring, receipts and reports and because it relies on open source can minimize the total costs of ownership. Scrutiny of the bibliography and market did not find any systems that could meet the aforementioned characteristics.

Routers in Internet face the problem of congestion due to the increased use of Internet. AQM algorithm is a solution to the problem of congestion control in the Internet routers. As data traffic is bursty in routers, burstiness must be handled without comprising the high link utilization and low queuing delay. Congested link causes many problems such as large delay, unfairness among flows, underutilization of the link and packet drops in burst. There are various existing algorithms that have been evolved over the past few years to solve these problems of congestion in routers. RED based algorithms only use queue length as congestion indicator to indicate congestion. In this paper, we propose an AQM scheme that considers only the advantages of these queue length based and uses the flow information and satisfies the QOS requirements of the network. This proposed scheme aims to provide good service under unresponsive load and shields the responsive flows from unresponsive flows to offer a good QOS to all users.

Telehealth has the potential to be a valuable tool for technical and clinical support of computer controlled prosthetic devices. This pilot study examined the use of Internet-based, desktop video conferencing for remote configuration of the Otto Bock C-Leg. Laboratory tests involved connecting two computers running Microsoft NetMeeting over a local area network (IP protocol). Over 56Kbs−1, DSL/Cable, and 10Mbs−1 LAN speeds, a prosthetist remotely configured a user's C-Leg by using Application Sharing, Live Video, and Live Audio. A similar test between sites in Ottawa and Toronto, Canada was limited by the notebook computer's 28Kbs−1 modem. At the 28Kbs-1 Internet-connection speed, NetMeeting's application sharing feature was not able to update the remote Sliders window fast enough to display peak toe loads and peak knee angles. These results support the use of NetMeeting as an accessible and cost-effective tool for remote C-Leg configuration, provided that sufficient Internet data transfer speed is available.
