  • An Adaptive Load Sharing Algorithm for Heterogeneous Distributed System
    tasks or load of the overloaded node will be sent to the under loaded node that has less processing weight to minimize the response time of the tasks Load balancing is a tool used effectively for balancing the load among the systems Dynamic load balancing takes into account of the current system state for migration of the tasks from heavily loaded nodes to the lightly loaded nodes In this paper we devised an adaptive load sharing algorithm to balance the load by taking into consideration of connectivity among the nodes processing capacity of each node and link capacity References Cited By M M Hayat S Dhakal C T Abdallah I Dynamic time delay models for load balancing Part II Stochastic analysis of the effect of delay uncertainty CNRS NSF Workshop Advances in Control of tirne delay Systems Paris France January 2003 J Ghanem C T Abdallah M M Hayat S Dhakal J D Birdwell J Chiasson and Z Tang Implementation of load balancing algorithms over a local area network and the internet 43rd IEEE Conference on Decision and Control Submitted Bahamas 2004 doi 10 1109 CDC 2004 1429411 L Anand D Ghose and V Mani ELISA An Estimated Load Information Scheduling Algorithm for Distributed Computing Systems Int l J Computers and Math With Applications vol 37 no 8 pp 57 85 Apr 1999 doi 10 1016 S0898 1221 99 00101 7 WEI Wen hong XIANG Fei WANG Wen feng et al Load Balancing Algorithm in Structure P2P Systems J Computer Science 2010 37 4 82 85 Khalifa A S Fergany T A Ammar R A Tolba M F Dynamic online Allocation of Independent tasks onto heterogeneous computing systems to maximize load balancing IEEE International Symposium on Signal Processing and Information Technology ISSPIT 2008 Page s 418 425 doi 10 1109 ISSPIT 2008 4775659 Andras Veres and Miklos Boda The chaotic nature of TCP congestion control In Proceedings of the IEEE Infocom pages 1715 1723 2000 doi 10 1109 INFCOM 2000 832571 J Chiasson J D Birdwell Z Tang and C T Abdallah The effect of time delays in the stability of load balancing algorithms for parallel computations IEEE Conference on Decision and Control Maui Hawaii 2003 doi 10 1109 CDC 2003 1272626 Ming wu and Xian He sun A General Self Adaptive Task Scheduling System for Non Dedicated Heterogeneous Computing In Proceedings of IEEE International Conference on Cluster Computing PP 354 361 Dec 2003 doi 10 1109 CLUSTR 2003 1253334 Z Zeng and B Veeravalli Design and Performance Evaluation of Queue and Rate Adjustment Dynamic Load Balancing Policies for Distributed Networks presented at IEEE Trans Computers 2006 pp 1410 1422 doi 10 1109 TC 2006 180 K Lu R Subrata and A Y Zomaya Towards decentralized load balancing in a computational grid environment in Proceedings of the first International Conference on Grid and Pervasive Computing 2006 Vol 3947 pp 466 477 Springer Verlag Press doi 10 1007 11745693 46 Acker D Kulkarni S 2007 A Dynamic Load Dispersion Algorithm for

  • Channel Aware Mac Protocol for Maximizing Throughput and Fairness
    routing protocol is a challenging task in MANET To overcome this drawback we are extending the previous work by improving the MAC protocol to maximize the Throughput and Fairness In this work we are estimating the channel condition and Contention for a channel aware packet scheduling and the queue length is also calculated for the routing protocol which is aware of the queue length The channel is scheduled based on the channel condition and the routing is carried out by considering the queue length This queue length will provide a measurement of traffic load at the mobile node itself Depending upon this load the node with the lesser load will be selected for the routing this will effectively balance the load and improve the throughput of the ad hoc network References Cited By Fan Wang Ossama Younis and Marwan Krunz Throughput oriented MAC for mobile ad hoc networks A game theoretic approach 2008 Published by Elsevier B V doi 10 1016 j adhoc 2007 12 002 Mariam Kaynia Nihar Jindal and Geir E Øien Improving the Performance of Wireless Ad Hoc Networks Through MAC Layer Design IEEE Transactions on Wireless Communications vol 10 no 1 January 2011 doi 10 1109 TWC 2010 110310 100316 Hongqiang Zhai Jianfeng Wang Xiang Chen and Yuguang Fang Medium Access Control in Mobile Ad Hoc Networks Challenges and Solutions 2006 doi 10 1002 wcm 376 P Priakanth Dr P Thangaraj Energy and Channel Aware MAC Protocol to Achieve Fairness in Multi Hop Mobile Adhoc Networks IJCSNS International Journal of Computer Science and Network Security VOL 8 No 4 April 2008 Zhifei Li Sukumar Nandi and Anil K Gupta Study of IEEE 802 11 Fairness and its Interaction with Routing Mechanism In the Fifth IFIP International Conference on Mobile and Wireless Communications Networks MWCN Singapore Oct
