While most existing data gathering routing protocols addressed the issue of energy efficiency, few of them, however, have considered the quality of the implied data aggregation process. In this work, an information model for sensed data is first formulated. A new metric for evaluating data aggregation process, data aggregation quality (DAQ), is formally derived. DAQ does not assume any prior knowledge on values or on statistical distributions of sensing data, and may be applied to most data gathering protocols. Next, two new protocols are proposed: the enhanced LEACH and the clustered PEGASIS, enhanced from two major existing protocols: the cluster-based LEACH and the chain-based PEGASIS. By carefully accounting for listening energy, energy efficiency of all four protocols is evaluated. In addition, DAQ is applied to evaluate their data aggregation process. It is found that, while chain-based protocols are more energy efficient than cluster-based protocols, they however suffer from poor data aggregation quality. DAQ may be readily applied to most of continuous data gathering protocols; it is therefore significant to future development of sensor network protocols.","PeriodicalId":305639,"journal":{"name":"First International Conference on Broadband Networks","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127704357","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}

Lumetta","doi":"10.1109/BROADNETS.2004.22","DOIUrl":"https://doi.org/10.1109/BROADNETS.2004.22","url":null,"abstract":"Survivability becomes increasingly critical in managing high-speed networks as data traffic continues to grow in both size and importance. In addition, the impact of failures is exacerbated by the higher data rates available in optical networks. It is therefore imperative to address network survivability in an efficient manner in order to design and operate reliable networks. Transparent optical networks (TONs) provide several advantages over optically opaque networks for supporting the growing communication demands, but suffer from several drawbacks that reduce the efficacy of most applicable capacity-efficient survivability techniques. In this paper, we introduce a novel protection algorithm (for single link and node failures) called streams. The streams algorithm is similar to 1:1 dedicated path protection in terms of implementation and operation overhead, and has identical recovery speeds while requiring less capacity. We compare the streams algorithm with dedicated and shared path protection in terms of capacity requirements, path lengths, and recovery time. We also extend the flooding based mesh restoration algorithm (FBMR) in order to provide a fair comparison in online routing scenarios, and report the relative tradeoffs between the different algorithms. Our results show that dynamically routed streams offer attractive tradeoffs in terms of capacity, path length, recovery speed, data loss and implementation complexity.","PeriodicalId":305639,"journal":{"name":"First International Conference on Broadband Networks","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133108226","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}

Most of the traditional restoration architectures are based on single-failure assumption which is unrealistic. Multiple link failure models, in the form of shared-risk link groups (SRLG's) and shared risk node groups (SRNG's) are becoming critical in survivable optical network design. We classify both these form of failures under a common heading of shared-risk resource groups (SRRG) failures. In our research, we propose graph transformation techniques for tolerating multiple failures arising out of shared resource group (SRRG) failures. Diverse routing in such multi-failure scenario essentially necessitates finding out two paths between a source and a destination that are SRRG disjoint. The generalized diverse routing problem has been proved to be NP-complete. The proposed transformation techniques however provide a polynomial time solution for certain restrictive failure sets. We study how restorability can be achieved for dependent or shared risk link failures and multiple node failures and prove the validity of our approach for different network scenarios.","PeriodicalId":305639,"journal":{"name":"First International Conference on Broadband Networks","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123966144","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}

Our main motivation is based on the observation that 802.11 DCF decreases the contention window to the initial value after each success transmission, which essentially assumes that each successful transmission is an indication that the system is under low traffic loading. GDCF takes a more conservative measure by halving the contention window size after c consecutive successful transmissions. This \"gentle\" decrease can reduce the collision probability, especially when the number of competing nodes is large. We compute the optimal value for c, and the numerical results from both analysis and simulation demonstrate that GDCF significantly improve the performance of 802.11 DCF including throughput, fairness, and energy efficiency. In addition, GDCF is flexible for supporting priority access by selecting different values of c for different traffic types; it is very easy to implement it, as it does not requires any changes in control message structure and access procedures in DCF.","PeriodicalId":305639,"journal":{"name":"First International Conference on Broadband Networks","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116065051","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}
