The current state of implementation and the introduction of transition is not focused on the implementation of mobility scenario communications protocol IPv4 over IPv6 protocol-based networks. The growing trend toward mobile access drives the development of mobility management in a dual-stack network environment. Implementation of IP mobility allows mobile users to roam from one network to another without causing significant network interruption. However, the existing implementation of dual-stack mobility does not provide an efficient platform for handling handover scenarios that leads to sub-optimal mobility experience. This study presents the implementation of the Distributed Mobility Management Proxy Mobile IPv6 (DMM PMIPv6) protocol on a dual-stack platform. This protocol was developed based on the concept of network in which the pointer is placed near the user's mobility or mobile node. The distributed control plane and the data infrastructure between entities are located on the edge of the access network which basically reduce the burden on the signalling process thus improving the handover performance. Therefore this study was initiated on existing protocol architecture for the implementation of mobility in the dual-stack scenario. This study proposes a dual-stack implementation of mobility based on DMM PMIPv6 protocol through IPv4 Home Address Mobility Support scenario that allows the mobile node capable of dual-stack and IPv4-based to communicate in IPv6-based network, in order to provide a better performance in terms of handover compared to the previous research implementations. DMM PMIPv6 Dual-Stack protocol testbed was implemented to investigate the handover performance. The results show that the mechanism provides better handover performance compared to the previous studies using PMIPv6 Dual-Stack implementation, thus able to provide a seamless connection to the user.","PeriodicalId":130300,"journal":{"name":"Asia-Pacific Journal of Information Technology & Multimedia","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130426069","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}

{"title":"Framework for the Implementation of E-Government System Based on Cloud Computing for Malaysian Public Sector","authors":"Nurul Elliza Jasmin, M. Hasan","doi":"10.17576/APJITM-2018-0701-01","DOIUrl":"https://doi.org/10.17576/APJITM-2018-0701-01","url":null,"abstract":"The implementation of e-government system requires the use of new technologies, methods and effective approaches. However, the development and maintenance of e-government system also requires a large allocation, not only related to the cost of hardware and software but also increase system cost, training, infrastructure needs and expansion of e-government system. In addition, the governance aspects of the implementation of e-Government in adapting the use of new technologies is given less attention. At the same time, cloud computing technology offers comprehensive utilization of resources through the Internet. Preliminary analysis shows that the concept of cloud computing is important for each government to facilitate the work, increase productivity and lead to cost savings. Therefore, this research aims to analyze and identify the key factors that contribute to the successful implementation of e-government system based on cloud computing. Literature reviews of previous studies have been conducted to obtain theoretical data, and interview techniques were used to obtain empirical data and there were seven related officers involved. In order to validate the proposed framework, expert review analysis was used. The framework combines three main factors; environment, process and product. Attributes in environment factors consist of people, law, organization and infrastructure which comprised of three deployment model of cloud computing; Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). Meanwhile, each process factor plays an important role and it consists of four stages; Plan, Do, Check and Act (PDCA) cycle to ensure the implementation of the system is continuously and thus producing a quality system. This framework can indirectly serve as a guide to government agencies as an action plan for implementing the e-government system based on cloud computing.","PeriodicalId":130300,"journal":{"name":"Asia-Pacific Journal of Information Technology & Multimedia","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123724481","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}
