Idealized Slotted ALOHA protocol is the most deploy variation in Mobile Ad Hoc Networks (MANETs) environment for example in digital cellular systems such as GSM, RFID and underwater wireless sensor network. In this research paper, the analysis and studies were made with simulation tools to get an illustration of how the Idealized Slotted ALOHA protocol works and to get mathematical results in graphical form in term of throughput and average time delay. These results are then used to compare with the performances of non-persistent CSMA protocol, another MAC protocol that happened to fell under the same category as ALOHA protocols to prove that Idealized Slotted ALOHA protocol outperforms non-persistent CSMA protocol. However, the throughput of Idealized Slotted ALOHA protocol is improvable with the right approaches. In this research paper, the approaches that are used to improve the performance made primarily are by amending the Idealized Slotted ALOHA protocol with capture effect and by increasing the CNR possibility values.","PeriodicalId":439852,"journal":{"name":"2014 4th World Congress on Information and Communication Technologies (WICT 2014)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116203273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The rapid evolution of mobile technology has triggered the need for conventional web-based e-Government systems to move towards another era known as Mobile Government (m-Government) systems. Although the functionality remains the same, the use of mobile devices in m-Government systems has caused the interface design of such systems to be dissimilar from the conventional web-based e-Government systems. Mobile devices in some ways have limited capacity in terms retrieving and displaying information, which makes their interface design to be quite tricky. This study aims to review the existing interface design frameworks in order to identify and collate the essential design elements that should be considered in designing the interface for m-Government systems. The study analysed qualitatively four m-Government interface design frameworks, namely 7Cs Design Elements, A Functional Design Approach for Mobile Government Website, Adaptive Mobile Government Framework and Framework of information Quality of Mobile Interface e-Government. By using content analysis, the study identified eight design elements from such frameworks. The study also highlighted the limitations of the current frameworks that could be explored further by future studies in interface design for m-Government systems.","PeriodicalId":439852,"journal":{"name":"2014 4th World Congress on Information and Communication Technologies (WICT 2014)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122057489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studies conducted in this area found that cost is the main reason why people would rather use the IMM compared to Short Message Service (SMS). However, in WhatsApp, photos send through the IMM will be located in local storage and eventually the local storage will run out of space. In this research our objective is to come out with a new framework of IMM application. It also introduces a way on how to save documents that sent via this application. The framework will benefit from the use of cloud storage service to store the new files created. In order to send files to the recipients, they need to be accessed via the cloud storage. Once sent, the files will be stored in the recipients' cloud storage. There will be an interface that allows communication between smart phone and cloud storage. As a result, the smart phone space will be saved and this new improvised framework is expected to be the basis of reference for optimizing the smart phone resource overhead.","PeriodicalId":439852,"journal":{"name":"2014 4th World Congress on Information and Communication Technologies (WICT 2014)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123998325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unfortunately, the strategy cause's other significant risks that could interrupt the ICT outsourcing venture's success. Information Security Risk (ISR) was considered among the critical significant risk in ICT Outsourcing project. Therefore the objective of this study is to explore the information security Vulnerabilities Risks Factor (VRF) critical level for ICT Outsourcing project characteristics through exploratory analysis approach. About 300 government agencies and private companies from various industries in Malaysia involved in the survey. However, 36% response was analyzed as a sample for the study population. Thus, Vulnerability Risks Factor (VRF) critical level was analyzed and discussed for each common ICT Outsourcing project characteristics implemented in Malaysia. The results of the analysis discovered the evidence of those ICT outsourcing project characteristics, risks exploited through Vulnerabilities Risks Factor (VRF). Several highly critical ICT outsourcing project characteristics were project team size between 10 to 99 members (33.6%), medium size project (28.2%) and outsource the ICT project to more than one service provider. The findings could be used as an indicator for organizations to prepare more effective information security management plan for ICT Outsourcing project. Eventually, the organization could give more priority to the specific ICT Outsourcing project characteristic where the Vulnerability Risks Factor (VRF) level is critical.","PeriodicalId":439852,"journal":{"name":"2014 4th World Congress on Information and Communication Technologies (WICT 2014)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128958903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
