Determinants of electronic commerce adoption in Malaysian SMEs' furniture industry

This paper aims to identify the determinants towards the adoption of e-commerce adoption particularly in Malaysia’s SMEs furniture industry. The scope of study in SMEs furniture industry can be considered as significant and appropriate in view of its establishments with significant effect to the overall Malaysian economy. The finding of the study indicated that adoption factors such as organizational readiness, external pressure, perceived ease of use and perceived benefit are positively related to ecommerce adoption. The result was found consistent with the outcome from previous studies in similar area. Hence, such generalization from the result of the study particularly in Malaysia SMEs can be considered as appropriate and relevant in view of the present competitive market environment that demands a better way of managing business as compared to the traditional means. Future research should take into considerations on other determinants towards the adoption of e-commerce among SMEs in Malaysia. For examples, top management support, presence of information technology (IT) skills, availability of consultancy, prioritization of e-commerce to the enterprise, perceived risk, enthusiasm of top management and compatibility with the work of the company.

The Use of ICT in Public and Private Institutions of Higher Learning, Malaysia

This study examines the extent of ICT utilization among the members of Faculty A of four public higher learning institutions (IPTA) and seven private higher learning institutions (IPTS) in Northern Malaysia. Its focus is on a) to investigate the extent of ICT resources provided by universities authorities, b) focus on types and extent of ICT usage in daily activities, c) to explore the ICT proficiencies level and d) to investigate the level of ICT integration in teaching activities. A total of 76 responses out of 77 from IPTA and only 105 out of 108 responses of IPTS are usable for further analysis in this study. Findings indicate that in the IPTA, though the facilities provided are not as plenty as in IPTS, the level of usage is quite encouraging. While in the IPTS, the levels of ICT usage among the educators are still not satisfactorily. Results also indicated that usage frequencies are more prone on informative in nature, besides integrating computer technology. Furthermore, the study also indicates that there were considerable differences in the use of ICT by educators in their perceived proficiencies and integrating computer technology. This study could be improved by expanding the total sampling population to all faculties in both universities. Methods of analysis could also be varied beyond the descriptive analysis done. Factors that could hinder the level of ICT usage by the educators could also be studied.

Software-Defined Network Testbed Using ZodiacFX a Hardware Switch for OpenFlow

Software-defined network (SDN) is a new programmable networking designed to perform tasks easier by enabling network administrators to add network control via a centralized control platform and open interfaces. Common network use procedures such as traffic shifts, troubleshooting and various types of device configuration. Thus devices are needed to reconfigure with the network, in order to create a reaction with events. In this paper, we have developed an SDN testbed using Zodiac FX a hardware switch for OpenFlow experiment. This research is utilized Zodiac FX a hardware switch to test the usage and discuss about the SDN controllers. Ryu controller is configured for testbed development. The main contribution of this paper in threefold as follows: first it provides the configuration of Ryu controller, second, it provides the configuration of Zodiac FX switch and lastly it develops a simple SDN testbed for OpenFlow.

Optimizing Congestion Control for Non Safety Messages in VANETs Using Taguchi Method

VANETs are the next uprising technology in automotive industry to promote safety and valuable information to make a better driving experience. This technology allows vehicle to communicate directly to the next vehicle and exchange data. The main purpose of VANETs is to improve traffic safety and to provide efficient traffic management on road via safety and non-safety message. Safety and non-safety messages are disseminated instantly among the vehicles through broadcasting protocol. By broadcasting, message can be delivered to multiple vehicles at the same time within vicinity. When too many vehicles broadcasting in dense traffic, VANETs suffer network congestion due to excessive amount of broadcast messages consume the bandwidth of communication channel. When broadcast storm occurs, message could not be delivered properly due to packet loss in the transmission. To address this issue, congestion control mechanism was proposed to alleviate the congestion in the communication channel during broadcast storm. In this research, the congestion control is applied to Service Channel communication (SCH) for non-safety message. The proposed congestion control was also tested using Taguchi method to optimize packet loss reduction in the network. The experiment was conducted with and without Taguchi method in urban area. The obtained results from the experiment show packet loss was greatly reduced when applying congestion control with Taguchi method. The results have proven that integrating Taguchi method in congestion control mechanism could improve packet loss reduction when broadcast storm take place in high-density traffic.

Experimental Model of Congestion Control Vehicular Ad Hoc Network Using OMNET

Vehicular Ad hoc Networks (VANET) are important Vehicle-to-Infrastructure (V2I) communication systems where vehicles are communicated by broadcasting and delivering transmission scheme and traffic information to each other. Due to both high mobility and high dynamic network topology, congestion control needs to be executed in a distributed way. Optimizing the congestion control in terms of percentage for delay, packet delivery ratio (PDR), and throughput could minimize the traffic packet transmissions. These have not been studied thoroughly so far—but this attribute will be essential for VANET applications and network performance. This paper presents a novel technique for congestion control and packet forwarding through Service Control Channel (SCH) channels in VANET. The Taguchi method has been applied in getting the optimize set of parameter for congestion control in highway scenario. This concept reduces the unnecessary traffic information and reduces the possibility of congestion in network based on performance metrics for delay, PDR, and throughput. The proposed technique performance is measured with the normal VANET scenario in V2I communication in highway driving conditions and the simulation results show that the performance of proposed scheme provides the better performance and improves the network performance with efficient bandwidth utilization.

A Congestion Control Optimal Model Design Perspectives of Non-safety Applications on Vehicular Ad Hoc Networks: A Survey of Requirements, Protocols, and Challenges

The issues of congestion control on non-safety applications in vehicular ad hoc networks (VANETs) have received considerable crucial attention in the field of intelligent transport systems (ITS). The critical challenges of ITS applications are in the events of intermittent connectivity and data collisions. Another challenge is the event-driven effect on both safety and non-safety applications that are critically relied on delay and reliability. So far, the development of protocol stacks for VANETs implies the WAVE protocol other IEEE 802.11p MAC protocol. Based on IEEE 802.11p MAC protocol standard in the 5.9 GHz band (other similar protocols such as C2C-CC for European and CALM from ISO) in which adopt of vehicle manufacturers of Information Communication Technology (ICT) to address the safety systems, emergency (breakdown, SOS), traffic control, environmental, navigational, and tracking. Little attention has been given to non-safety applications, for instance, chat, twitter, SMS, internet services, video-on-the-go, etc. Besides, roadside-vehicle communications (RVC) caters for information concerning repair notifications, remote diagnostics, context information, navigation information, and alerts system. In this survey, we present a framework that proposes a guideline and recommendation for the congestion control mechanism perspectives in VANETs. In particular, researches are centered on the investigation of the mobility model of congestion control algorithms. Finally, this survey contributes to appropriate knowledge and challenges in legacy congestion control of VANETs and toward the future research development.
