Research ArticleOpen accessIn the abstractKey Exchange Protocol in Elliptic Curve Cryptography with No Public PointK. Kaabneh, H. Al-BdourIn recent years some cryptographic algorithms have gained popularity due to properties that make them suitable for use in constrained environment like mobile information appliances, where computing resources and power availability are limited. One of these cryptosystems is Elliptic curve which requires less computational power, memory and communication bandwidth compared to other cryptosystem. This makes the elliptic curve cryptography to … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 7,069 accessesView PDFCite
Case ReportOpen accessIn the abstractWeb-Based Emergency Management Information System for Landslides OccurrencesJordan H. Souza, Carlos A.P. Soares, Gislaine Santos, Wainer S. SilvaLandslides cause significant human and environmental damage, as well as unpredictable damage to structures and buildings. This paper presents the development and application of a web-based system for risk management in landslide-related emergency preparedness. This system allows for easy access to information, even in hard-to-reach regions, by integrating mobile internet devices, like cell phones and tablets, with GPS systems, without … …American Journal of Environmental Sciences, Vol. 13, Issue 1 · 11 Jan 2017 · 7,551 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpatial Representation to Support Visual Impaired PeopleAbbas Mohamad Ali, Shareef Maulod ShareefThe rapid development of Information and Communication Technology (ICT) enhances the government services to its citizen. As a consequence affects the exchange of information between citizen and government. However, some groups can experience some difficulties accessing the government services due to disabilities, such as blind people as well as material and geographical constraints. This paper aims to introduce a novel … …Journal of Computer Science, Vol. 11, Issue 3 · 15 Apr 2015 · 6,198 accessesView PDFCite
Research ArticleOpen accessIn the abstractEXTENDED-RANDOMIZED, EFFICIENT, DISTRIBUTED: A DYNAMIC DETECTION OF CLONE ATTACKS IN STATIC WIRELESS SENSOR NETWORKSC. Geetha, M. RamakrishnanA wireless sensor network is a collection of nodes organized in to a cooperative network. Each node consists of processing capability, multiple types of memory, a power source and actuators and sensors. This wireless sensor network is established in hostile and harsh environments like civil and military applications. This network is prone to various attacks. One of the major attack … …Journal of Computer Science, Vol. 10, Issue 10 · 6 May 2014 · 6,747 accessesView PDFCite
Research ArticleOpen accessIn the abstractENERGY EFFICIENT NETWORK SELECTION USING 802.16G BASED GSM TECHNOLOGYH. Anandakumar, K. UmamaheswariHandover is the mechanism that transfers information from one terminal to another as a user moves through the coverage area of a cellular system. Here the Network selection is the handover decision process between various network environments. This handover decision will be either mobile or network initiated. In 2G GSM handover decision method especially concentrates on Received frequency signals (RFS). … …Journal of Computer Science, Vol. 10, Issue 5 · 31 Dec 2013 · 7,081 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdvanced Energy Efficient Passive Clustering Mobility in Wireless Sensor NetworksAouad Siham, Maach Abdelillah, El Ganami DrissWireless sensor networks have a wide applicability and increase deployment in the near future. In most of those applications, the network is composed of an important number of nodes deployed in an extensive area in which not all nodes are directly connected and based on clustering techniques. The Clustering can considerably reduce transmission overhead during flooding. In fact, by using … …American Journal of Applied Sciences, Vol. 10, Issue 12 · 24 Oct 2013 · 6,762 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Evaluation of Probabilistic Relay in Ad Hoc On-demand Distance Vector and Ad Hoc On-demand Multipath Distance Vector Under Highly Dynamic EnvironmentsRadityo Anggoro, Teruaki Kitasuka, Ryoji Nakamura, Masayoshi AritsugiVehicular Ad hoc Networks (VANETs) are a specific class of Mobile Ad hoc Networks (MANETs). Since vehicles tend to move in a high speed, the network topology is rapidly changed. Thus vehicle’s connectivity problem is one of the interesting issues in VANETs. Ad hoc On-demand Multipath Distance Vector (AOMDV) is an extended version of ad hoc on-demand distance vector (AODV). … …Journal of Computer Science, Vol. 9, Issue 7 · 22 Jun 2013 · 7,054 accessesView PDFCite
Research ArticleOpen accessIn the abstractAgent and Radio Frequency Identification Based Architecture for Supermarket Information SystemHasan Al-SakranIn recent years the acceptance of Radio Frequency Identification (RFID) technology in business environments has been increasing rapidly due to its competitive business value. Adopting a suitable RFID-based information system has become increasingly important for supermarkets. However, most supermarkets still use conventional barcode-based systems to manage their information processes, which are consistently reported as one of the most unenthusiastic aspects … …Journal of Computer Science, Vol. 9, Issue 6 · 1 Jun 2013 · 6,746 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancing Security in E-Health Communications using Multi-Agent SystemRossilawati Sulaiman, Dharmendra Sharma, Wanli Ma, Dat TranProblem statement: In this study, we address the security needs in online communications, specifically in the e-health domain. We focus on how to provide different security strengths to different types of communications in e-health, where each communication transmits different types of information with different levels of sensitivity. Approach: The Multi-Agent System (MAS) approach is used to develop an agent-based system … …Journal of Computer Science, Vol. 8, Issue 5 · 17 Feb 2012 · 6,986 accessesView PDFCite
