Research ArticleOpen accessEvery word in the titleNew Solution for Reducing Doppler Shift in the MB-OFDM System Over High Mobility Multipath Channel for V&I CommunicationSanaa Kabil, Raja Elassali, Fouzia Elbahhar et al.The MB-OFDM has been proposed as a good candidate to ensure Vehicle to Infrastructure communication (V&I). Fast moving vehicles present challenges for the proposed system especially for high mobility (250 km h-1). The main objective in this study is to study and investigate the impact of Doppler shift on the quality of transmitted/received signal in terms of Bit Error Rate … …American Journal of Applied Sciences, Vol. 12, Issue 3 · 29 Apr 2015 · 7,170 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNETWORK MOBILITY SUPPORTED PROXY MOBILE IPV6Ananthi Jebaseeli SamuelRaj, Sundararajan Jayapal, Vijayaraghavan VaradharajanProxy Mobile IPV6 (PMIPV6) is a network-based mobility management protocol, designed to keep track of individual mobile node's movement. So a mobile node can easily roam in PMIPV6 network without changing it's IP address. Network Mobility-Basic Support Protocol (NEMO-BSP), based on MIPV6, is the protocol designed for mobility management of NEMO in MPIV6 network. But NEMO-BSP cannot be directly used … …Journal of Computer Science, Vol. 10, Issue 9 · 26 Apr 2014 · 6,632 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMobility of Heavy Metals in Plants and Soil: A Case Study From A Mining Region in CanadaM. Mehes-Smith, K. K. Nkongolo, R. Narendrula, E. CholewaUnderstanding the dynamic of metals in soil and plantsis essential for ecosystem management and risks assessment of environmental pollution and sustainability.The main objective of the present study is to determine the mobility of Ni, Cu, Fe, Mg and Zn in soil and their translocation in D. cespitosa plants in a mining region in Northern Ontario.The total amount of Cu, Ni, … …American Journal of Environmental Sciences, Vol. 9, Issue 6 · 15 Jan 2014 · 8,677 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIPv6 Network Mobility Route Optimization SurveySamer Sami Hassan, Rosilah HassanProblem statement: This study describes that the Next Generation of Networks (NGN) communication will supports multiple technologies, handles the mobility of end users to move through heterogeneous access networks, with ability to connect to different networks. Where the Internet Engineer Task Force maintain (IETF) the Mobile IPv6 (MIPv6) to handles the mobility of networks (NEMO), to provide wide band and … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 7,243 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePore Water Pressure Contribution to Debris Flow MobilityChiara DeangeliProblem statement: Debris flows are very to extremely rapid flows of saturated granular soils. Two main types of debris flow are generally recognized: Open slope debris flows and channelized debris flows. The former is the results of some form of slope failures, the latter can develop along preexisting stream courses by the mobilization of previously deposited debris blanket. The problem … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 6,588 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMobility Management Technique for Real Time Traffic in 802.11 NetworksGurpal Singh, Ajay Pal Singh Atwal, B.S. SohisA practical mobility management technique aimed at reducing handoff latency to less than 10ms has been proposed and implemented in this paper. Handoff latency has been reduced by decoupling scanning from handoff execution process. This scheme has been implemented in the form of client side application with modifications to open source Madwifi new generation driver. Performance of this mobility management … …Journal of Computer Science, Vol. 3, Issue 6 · 30 Jun 2007 · 6,779 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePerformance Analysis of Call Admission Control in WCDMA Systems with Mobility based Interference Margin ReservationS. Malarkkan, V. C. RavichandranThis study presents performance of call admission control and resource reservation schemes based on the mobility of the users in WCDMA cellular systems. In order to guarantee the handoff dropping probability, the mobility of the user is predicted based on a realistic mobility model. The mobility prediction scheme used in this study is used to estimate the set of candidate … …Journal of Computer Science, Vol. 2, Issue 10 · 31 Oct 2006 · 6,384 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMobility and Handover Technique in Heterogeneous Wireless NetworksRadhwan Abdullah, Zuriati Zukarnain, Farzaneh Masoumiyan, Azizol AbdullahThe management techniques for Mobile IPv6 between different wireless technologies are very important to complete the handover process with the least possible delay. In the fast handover, when a mobile node moves to another network, it needs to do handover operations. These operations have a severe impact on the handover latency. This paper proposes an Enhanced Advanced Duplicate Address Detection … …Journal of Computer Science, Vol. 11, Issue 3 · 31 Mar 2015 · 6,752 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAdvanced 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 · 6,756 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHeavy Metal Mobility in Polluted Soils: Effect of Different TreatmentsMarta Susana Zubillaga, Emiliano Bressan, Raúl Silvio LavadoThe effects of biosolid compost and phytoremediation applied on the leaching of cadmium, copper, lead and zinc, through the different horizons of a superficially polluted soil were determined.
