To overcome problems of IP multicast, overlay multicast in which multicast functionalities are implemented at end hosts has been proposed. However, unlike IP multicast non-leaf nodes in the multicast delivery tree are normal end hosts which can join and leave the tree freely. This causes the multicast tree unstable and disrupted nodes to rejoin the tree. In this paper, we propose that each node when joining the multicast tree sets its leaving time, i.e. how long it will stay in the tree, and sends join request to a number of nodes which are already on the tree. Using the leaving time of nodes, new nodes are joined at the tree such that a child's leaving time is earlier than its parent, i.e. the child will leave the tree earlier than its parent. This makes the tree more stable than joining at random nodes in the tree. Furthermore, we propose a proactive recovery mechanism so that even if a parent leaves the tree and children do not, children can rejoin at predetermined nodes immediately, so that the recovery time of the disrupted nodes is minimum. We have shown by simulation that there is less overhead when joining the multicast tree and the recovery time of the disrupted nodes is much less than the previous works.","PeriodicalId":312802,"journal":{"name":"2009 International Conference on Network-Based Information Systems","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123112924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have to consider how to save the energy consumption anywhere and anytime, including a large set of servers, for example, servers in the Google company. Hence, power and energy consumption has recently become key concerns, especially huge number of servers are deployed in large cluster configurations as in data centers and Web hosting facilities. Even though we emphasize power saving as much as possible, the performance of servers should be ensured. So far, there have been some discussions about enhancing power conservation. However, with the best of our knowledge, a mathematical model about consumed power and server’s performance has not been discussed. Therefore, in this paper, we attempted to minimize the energy consumption with performance constraint of web servers. We know, the response time is the focus of the performance in web servers. Therefore, we first find the trade off value of load for each server based on optimized methods. With the trade off load, the performance of users can be satisfied at the same time the power consumption is minimized. Then, using the trade off load value, we propose a novel load allocation method and then discuss the effectiveness of our load allocation method by comparing with other two methods: random load allocation method and average load allocation method.","PeriodicalId":312802,"journal":{"name":"2009 International Conference on Network-Based Information Systems","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122381998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A WSN is normally constructed from large numbers of low-power, inexpensive sensor devices that are densely embedded in the physical environment, operating together in a wireless network. Being energy constrained, the network environment requires a communication protocol to maximize the lifetime of each node in WSN. Sensor-Medium Access Control (S-MAC) is a contention-based protocol designed specifically for WSN. It’s operational principle is based on a periodic cycle, in which nodes take turns to sleep and wake-up to listen for awhile. The focus of this paper is to investigate and implement border nodes, or gateways in S MAC, using network simulator-2 (ns-2). Border nodes have been previously defined, however, the life cycle of border nodes has not, nor have they been implemented and tested under a simulation package such as ns-2. We introduce the birth and death of border nodes in the implementation of S-MAC. Our simulation results demonstrate that, with border nodes implementation, the network latency is increased at the cost of prolonged network life.","PeriodicalId":312802,"journal":{"name":"2009 International Conference on Network-Based Information Systems","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126376925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
