Research ArticleOpen accessIn the abstractAn Analysis of Power Aware Congestion Control Multipath Multicast Protocol for Mobile Ad hoc NetworkDuraiswamy Karuppaswamy, Vijayaragavan ShanmugamProblem statement: In MANETs, wireless link transmission errors, mobility and congestion are major causes for packet loss. Mobility may cause packet loss in different ways. Whereas congestion in a network occurs, whenever the demands exceed the maximum capacity of a communication link especially when multiple hosts try to access a shared media simultaneously. Approach: In this study, we proposed a … …Journal of Computer Science, Vol. 6, Issue 12 · 2 Nov 2010 · 7,044 accessesView PDFCite
Research ArticleOpen accessIn the abstractLink Stability and Node Energy Conscious Local Route-Repair Scheme for Mobile Ad Hoc NetworksAnuradha Banerjee, Paramartha DuttaProblem statement: A mobile ad hoc network is a self-configuring network of mobile nodes connected by wireless links. As the nodes are free to move randomly, topology of the network may change rapidly and unpredictably. As a result, intermediate nodes in the communication routes tend to lose connection with each other during the communication process. In order to repair a … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 6,862 accessesView PDFCite
Research ArticleOpen accessIn the abstractDelay Analysis and System Capacity Control for Mobile WiMAX Relay NetworksAnas F. Bayan, Tat-Chee Wan, Sureswaran RamadassProblem statement: WiMAX relay is an emerging cost effective wireless last mile solution for rural and urban broadband Internet access. Approach: One of the key concerns of WiMAX operators is how many users they can support for an access area where the number of users and the amount of data that can be delivered to the end user depends on … …Journal of Computer Science, Vol. 6, Issue 10 · 5 Aug 2010 · 7,430 accessesView PDFCite
Research ArticleOpen accessIn the abstractHistory Based Contention Window Control in IEEE 802.11 MAC Protocol in Error Prone ChannelAli Balador, Ali Movaghar, Sam JabbehdariProblem statement: IEEE 802.11 Medium Access Control (MAC) protocol is one of the most implemented protocols in this network. The IEEE 802.11 controls the access to the share wireless channel within competing stations. The IEEE 802.11 DCF doubles the Contention Window (CW) size for decreasing the collision within contending stations and to improve the network performances but it is not … …Journal of Computer Science, Vol. 6, Issue 2 · 28 Jul 2010 · 7,667 accessesView PDFCite
Research ArticleOpen accessIn the abstractAutomated Position System Implementation over Vehicular Ad Hoc Networks in 2-Dimension SpaceSoumen Kanrar, Mohammad SirajProblem statement: The real world scenario have changed from the wired connection to wireless connection. Over the years software development has responded to the increasing growth of wireless connectivity in developing network enabled software. The problem arises in the wireless domain due to random packet loss in transport layer and as well as in data link layer for the end … …Journal of Computer Science, Vol. 6, Issue 2 · 28 Feb 2010 · 7,196 accessesView PDFCite
Research ArticleOpen accessIn the abstractLot-Sizing Decisions under Trade Credit Depending on the Ordering Quantity in Fuzzy Annual DemandChui-Yu Chiu, Zhi-Ping Lin, Yi LinProblem statement: In reality, there are of various products such as liquids, volatile, medicines and materials, in which the rate of deterioration is very large. However, little attention has been mentioned what the effects of deterioration occur in most inventory systems. Also, the loss of the deterioration should not be neglected as an important issue. Approach: In this study, we … …American Journal of Applied Sciences, Vol. 6, Issue 12 · 31 Dec 2009 · 6,767 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Evaluation of Stable Weight-Based on Demand Routing Protocol for Mobile Ad Hoc NetworkOon Chong Hsi, Azizol AbdullahProblem statement: A MANET is an autonomous collection of mobile users that communicate over relatively bandwidth constrained wireless links. Since the nodes are mobile, the network topology may change rapidly and unpredictably over time. Approach: A Stable Weight-based On demand Routing Protocol (SWORP) that uses the weight-based route strategy to select a stable route was created by Wang. But SWORP … …Journal of Computer Science, Vol. 5, Issue 10 · 31 Oct 2009 · 6,933 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetecting Hornbeam Trees Phenological Characteristics of Mountain ForestSasan Babaei Kafaki, Asadollah Mataji, Seyed Armin HashemiProblem statement: Phenology is the study of the seasonal occurrence of developmental or life cycle events, such as bud break, flowering, or autumn leaf drop. The proposed study attempted to quantify changes in Carpinus betulus L. phenology of deciduous broad leaf forest between the years 2003-2006. Approach: Phenological studies were fulfilled during four years as from January 2003-December 2006 by … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 7,278 accessesView PDFCite
Research ArticleOpen accessIn the abstractMPLS Based Architecture for Mobility and End-to-End QoS Support in Fourth Generation Mobile NetworksAlejandro Quintero, Eduardo Del FrutosProblem statement: Next-generation mobile networks are evolving towards network architectures relying entirely on IP. Approach: These networks had to be scalable in order to support future IP traffic, namely new multimedia services and real time applications, while providing an effective mobility management mechanism to cope with increasingly mobile users. In addition to global connectivity, next-generation mobile networks will have to … …Journal of Computer Science, Vol. 5, Issue 4 · 30 Apr 2009 · 7,691 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Comparison of Two On-demand Routing Protocols for Ad-hoc Networks based on Random Way Point Mobility ModelGeetha Jayakumar, G. GopinathAd hoc networks are characterized by multihop wireless connectivity, frequently changing network topology and the need for efficient dynamic routing protocols plays an important role. We compare the performance of two prominent on-demand routing protocols for mobile ad hoc networks: Dynamic Source Routing (DSR), Ad Hoc On-demand distance Vector Routing (AODV). A detailed simulation model with MAC and physical layer … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,693 accessesView PDFCite
