“…It was built using library standards and protocols that allow Koha to interact well with other existing workflows from different systems. Koha works using OPAC, and it is compliant with XHTML, CSS and JavaScript, making its platform-independent [22]. Koha is the enterprise resource planning system used for automating and integrating information management practices in an organization.…”

Most public and private libraries are inclined to adopt using Koha ILS around the globe. However, several Arab schools could not implement the Koha ILS application to automate their school libraries for ease of use. Deploying technology in managing libraries can solve several identified issues in public and private schools. This provides efficiency, ease and improves the performance of library services. Therefore, this paper is based on qualitative research that implements an efficient open-source application known as Koha ILS in two Arab schools, namely Baseerah International School (BIS) and International Modern Arab School (IMAS), Kuala Lumpur, Malaysia. In our analysis, we consider analyzing the proposed Koha ILS by providing backend accessibility so as library consumers can make a further enhancement to upgrade the application. The proposed Koha presents several positive impacts such as an efficient cataloging system, remote management of library consumer records such as books or room reservations and customizable searching interface for efficient usage. The application also presents multiple operating system support for a user’s flexibility. In our results, an analysis was made by comparing the two schools based on gender, position/ranks available in the school library, and IT gadgets. Toward this end, some limitations were noted and recommended as a future research direction.

“…The authors propose a new RV selection algorithm which selects the RV resulting in the longest lifetime of the route between SV and AP. In [4], a multi metric relay selection algorithm is proposed which is based on the received signal strength (RSS), route life time (RLT) and available relay capacity. The performance of a relay selection scheme for cooperative vehicular networks with the decodeand-forward (DF) protocol is analyzed in [5], and the "best" vehicle which satisfies an index of merit is selected as relay.…”

Vehicular Ad hoc Network (VANET) has recently received considerable attention both from academia and industry. In VANET, both safety related application and user application are expected to be supported through the communication between vehicles and access points (AP), To deal with the problem of short connectivity duration and low throughput of user service in VANET due to the mobility of vehicles and the limited coverage of APs, relay vehicles (RVs) can be applied in VANET. However, in the case that multiple candidate RVs are available, the problem of selecting the optimal RVs has to be considered. In this paper, utility based relay vehicle selection algorithm is proposed which jointly considers multiple metrics from multiple protocol layers, including characteristics of physical layer, the link status, bandwidth and delay characteristics of relays and user service requirement, and utility functions are applied to outrank the candidate relays for both delay sensitive service and throughput sensitive service, respectively. Simulation results demonstrate that comparing to previous algorithms, the proposed algorithm offers better performance in terms of average throughput, the transmission delay and packet loss could also be reduced.

“…In a heterogeneous vehicular environment, vehicle users have the opportunity to use different types of the radio access technologies (RATs) with varying capability and load at different locations. The development of intelligent transportation system (ITS) makes the onboard unit (OBU) devices have multiple interfaces which can connect to multiple networks simultaneously [1], [2]. Though, the operating environment of these networks may change rapidly especially in a high dynamic network environment.…”

It cannot be denied that, the inescapable diffusion of smartphones, tablets and other vehicular network applications with diverse networking and multimedia capabilities, and the associated blooming of all kinds of data-hungry multimedia services that passengers normally used while traveling exert a big challenge to cellular infrastructure operators. Wireless fidelity (Wi-Fi) as well as fourth generation long term evolution advanced (4G LTE-A) network are widely available today, Wi-Fi could be used by the vehicle users to relieve 4G LTE-A networks. Though, using IEE802.11 Wi-Fi AP to offload 4G LTE-A network for moving vehicle is a challenging task since it only covers short distance and not well deployed to cover all the roads. Several studies have proposed the offloading techniques based on predicted available APs for making offload decision. However, most of the proposed prediction mechanisms are only based on historical connection pattern. This work proposed a prediction model which utilized historical connection pattern, vehicular movement, and driver profile to predict the next available AP. The proposed model is compared with the existing models to evaluate its practicability.
