Research ArticleOpen accessIn the abstractSecondary User Sensing Time Optimization in Sensing-Transmission Scheduling for Dynamic Spectrum Access in Cognitive RadioInderdeep Kaur Aulakh, Renu VigThe constraint of limited frequency spectrum for wireless communication is very daunting. The radio spectrum licensed to permanent users is wasted at times when not used continuously. Cognitive radio technology involves a change in regulation of radio spectrum. In cognitive radio networks a secondary user network is designed for efficiently using gaps in spectrum and not causing at the same … …Journal of Computer Science, Vol. 11, Issue 8 · 5 Nov 2015 · 7,343 accessesView PDFCite
Research ArticleOpen accessIn the abstractMulticast Node Communication Using Virtual Queue with Process SchedulingS. Sumalatha, G. Sreenivasulu, G. Uday Kiran BhargavaMulticast technique is used to transmit node data from one source node to many destination nodes simultaneously and establish a communication in the network. In multicasting communication, node network packet collision occurrence is a frequent problem in real time network system. The node packet collision avoidance using virtual queue with process scheduling is discussed in this study and proposed central … …Journal of Computer Science, Vol. 11, Issue 2 · 28 Jan 2015 · 6,176 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficient Scheduling of Packets in Wireless Sensor Networks Using Priority Based Scheduling ApproachB. Booba, T.V. GopalThe packet scheduling is essential and plays an important role to sense the element nodes with resource constraints in Wireless Networks. The packet scheduling scheme also scale the energy consumption and end-to-end information transmission delay in time period and non-real-time information packets during wireless transmission. The proposed Priority based Packet Scheduling (PPS) technique has a tendency to overcome the issues … …Journal of Computer Science, Vol. 11, Issue 1 · 9 Aug 2014 · 7,091 accessesView PDFCite
Research ArticleOpen accessIn the abstractIMPLEMENTATION OF CENTRAL QUEUE BASED REALTIME SCHEDULER FOR MULTIPLE SOURCE DATA STREAMINGV. Kaviha, V. Kannan, S. RaviReal-time data packet sources are required to remain robust against different security threats. This study proposes a real-time secure scheduling strategy for data transmission to enhance the communication throughput and reduce the overheads. The proposed system combines real-time scheduling with security service enhancement, error detection and realtime scheduler based on EDF algorithm using uc/os-II real time operating system, implemented on … …Journal of Computer Science, Vol. 10, Issue 9 · 22 Apr 2014 · 6,381 accessesView PDFCite
Research ArticleOpen accessIn the abstractA COMBINED LOW LATENCY AND WEIGHTED FAIR QUEUING BASED SCHEDULING OF AN INPUT-QUEUED SWITCHK. Bommanna Raja, D. RaghupathikumarInput queuing has become dominant and popular building blocks for high speed crossbar switches with many ports and fast line rates because they require minimum speed-up of memory bandwidth. Input Queued switches with finite Virtual Output Queues guarantees QoS performance in terms of throughput and average delay. A switch performs two functions Queuing and Scheduling. Queue Management algorithm manages the … …Journal of Computer Science, Vol. 10, Issue 8 · 25 Mar 2014 · 7,226 accessesView PDFCite
Research ArticleOpen accessIn the abstractCOMPARISON FOR WIMAX SCHEDULING ALGORITHMS AND PROPOSAL QUALITY OF SERVICE IMPROVEMENT IN WIMAX NETWORKSR. Nandhini, N. DevarajanThe objective of the broadband wireless technologies is to ensure the end to end Quality of Service (QoS) for service classes. Wimax is a revolution in wireless networks which could support real time multimedia services. In order to provide QoS support and efficient usage of system resources an intelligent scheduling algorithm is needed. The design of detailed scheduling algorithm is … …American Journal of Applied Sciences, Vol. 11, Issue 1 · 19 Nov 2013 · 7,394 accessesView PDFCite
Research ArticleOpen accessIn the abstractDYNAMIC PLANNING BASED SCHEDULING APPROACH FOR WIRELESS SENSOR NETWORKSM. Senthil Kumaran, R. RangarajanEnergy efficiency is an important issue in wireless sensor networks. A sensor node has a microprocessor and a small amount of memory for signal processing and task scheduling. Dynamic Planning is a method is used in this approach it combines the flexibility of dynamic scheduling with the predictability offered by schedulabilty check.

Research ArticleOpen accessIn the abstractPriority Based Congestion Detection and Avoidance in Wireless Sensor NetworksR. Beulah Jayakumari, V. Jawahar SenthilkumarThe primary objective of event driven wireless sensor networks is to route the detected or monitored data at the earliest to the base station depending on their degree of priority since the data generated in a sensor network has different importance. In order to avoid indiscriminate dropping of data during congestion we propose a novel congestion protocol named priority based … …Journal of Computer Science, Vol. 9, Issue 3 · 26 Apr 2013 · 6,732 accessesView PDFCite
Research ArticleOpen accessIn the abstractCluster Based Time Division Multiple Access Scheduling Scheme for Zigbee Wireless Sensor NetworksB. Meenakshi, P. AnandhakumarIn IEEE 802.15.4 ZigBee Wireless Sensor Networks, an efficient scheduling mechanism is required for reliable data transmission. Further, concurrent transmission of huge data through CSMA/CA incurs more packet collision rate. This complicated condition has to be eliminated to improve the system throughput. In this study, we propose to deploy cluster based TDMA scheduling mechanism for IEEE 802.15.4 ZigBee Wireless Sensor … …Journal of Computer Science, Vol. 8, Issue 12 · 26 Nov 2012 · 6,682 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Forager Bee's Intelligence Inspired Dynamic Queue Scheduling for the Internet TrafficY. Suresh, S. Arumugam, M. A. BhagyaveniProblem statement: In the present evolution of large scale internet communication, per flow control scheme faces scalability issue due to tremendous number of flows. The aggregation based approaches such as differentiated architecture relieve the storage of state of flows in core router.
