They try to address the unique challenges that MANETs present over traditional wired networks. Some of these challenges are: use of unreliable wireless medium for communication; frequent change in topology; lack of a central authority to arbitrate communication in the network. These protocols find a route to a destination, if such a route exists. However in the wireless medium, links are susceptible to frequent failures which can cause partitions in the network. Current routing protocols use a passive delivery approach for packets destined to a host in another partition. Packets destined to a disconnected host are dropped after some route repair attempts. The paper presents a novel protocol, Voila/spl grave/, that delivers messages across disconnected hosts. Voila/spl grave/ uses nodes moving between the source and destination partitions to act as carriers of messages. It uses a novel carrier select algorithm to select carrier nodes in the source partition.","PeriodicalId":366183,"journal":{"name":"29th Annual IEEE International Conference on Local Computer Networks","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131618971","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 use discrete-event simulation to evaluate and prototype RapidIO-based systems with respect to their performance in an environment targeted towards space-based radar applications. This application class makes an ideal test case for a RapidIO feasibility study due to high system throughput requirements and real-time processing constraints. Our results show that a baseline RapidIO system is well suited to space-based radar, providing significant improvements over typical bus-based architectures. Our results also show that extensions to the RapidIO protocol such as cut-through routing and transmitter-controlled flow-control would provide minimal performance improvements for the applications under study.","PeriodicalId":366183,"journal":{"name":"29th Annual IEEE International Conference on Local Computer Networks","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132178394","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}

The direct attached storage (DAS) model is being replaced by storage area networks (SANs). SANs provide the capability to distribute the storage across multiple servers leading to decentralized and externalized storage. Recently, the accessibility of SANs to small companies has been improved by using existing IP networks to distribute storage over long geographical distances, leading to the distributed storage area network (DSAN). Although DSANs have provided additional capabilities to SANs, they have created a new set of problems for enterprise class applications, like Microsoft Exchange Server 2003, with increasing end to end latency (ETEL), due to large physical cable lengths. We present an attempt to analyze the effect of ETEL in DSAN on the performance of Microsoft Exchange Server 2003 by monitoring the Exchange behavior using LoadSim 2003 benchmark.","PeriodicalId":366183,"journal":{"name":"29th Annual IEEE International Conference on Local Computer Networks","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127796692","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 consider these issues in the design of a simple, scalable, energy-efficient location aided routing (SELAR) protocol for WSN. In SELAR, location and energy information of neighboring nodes together with the location information of the sink node are used to perform the routing function. Through simulations, we show that SELAR performs considerably better than flooding in terms of network lifetime, energy distribution, and amount of data delivered.","PeriodicalId":366183,"journal":{"name":"29th Annual IEEE International Conference on Local Computer Networks","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114585362","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}

These networks require that the switches used offer line-rate switching as well as bounded latency and jitter. Gigabit Ethernet offers an interesting replacement to traditional proprietary networks because of its high performance and low cost. We develop a framework for analyzing the abilities of Gigabit Ethernet switches to provide probabilistic guarantees for reliably low latency using quality of service (QoS) controls. From the perspective of control capabilities, management complexity, and implementation success we compare the strengths and weaknesses of three modern Ethernet switches. These switches exhibit a broad range of configuration options and are representative of the different levels of QoS implementation available today. We use the performance metrics of latency, jitter, and packet loss to characterize the success of a service policy. The results from a variety of network, load, and traffic scenarios are presented in terms of these metrics. Through the results, we are able to gain insight into the individual switch implementations of QoS.","PeriodicalId":366183,"journal":{"name":"29th Annual IEEE International Conference on Local Computer Networks","volume":"222 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122086363","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}

Although wireless sensor systems usually have available received signal strength (RSS) readings, this useful information has not been effectively used in the existing localization algorithms. The existing range-free algorithms do not use this information, and the range-aware algorithms require sophisticated range techniques to estimate ranges. In this paper, we introduce and develop a partial-range-aware localization scheme utilizing RSS readings. The scheme can be implemented in a distributed way and can be used in any hop-based range-free algorithms to improve their localization accuracy. Through extensive simulation, the results show that the partial-range-aware algorithm can improve the localization accuracy by reducing position errors up to 50% of the previous range-free localization results.","PeriodicalId":366183,"journal":{"name":"29th Annual IEEE International Conference on Local Computer Networks","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128541886","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}
