AMCM is based on the IEEE 802.11 MAC but provides fine-grain, asynchronous coordination among locally interfering nodes for channel negotiation. By incorporating load-awareness, channel availability awareness and batch transmissions, our window-based approach achieves high channel utilization under varying load, while avoiding the control-window saturation problem as the number of channels increases. For single-hop scenarios, we show that, at low load, AMCM is comparable to IEEE 802.11 MAC, while under high load, AMCM delivers almost Nx improvement gain over IEEE 802.11 MAC protocol, where N is the number of channels. AMCM also outperforms existing multi-channel MAC protocols by 100% and 150% respectively under high load at a lower hardware cost and complexity. In multi-hop scenarios, AMCM achieves performance improvement of 190% and 90% for both dense and sparse network over IEEE 802.11 MAC respectively. In both scenarios, AMCM achieves close to full utilization of all channels with good protocol efficiency.","PeriodicalId":147887,"journal":{"name":"2006 3rd International Conference on Broadband Communications, Networks and Systems","volume":"2012 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116052893","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 camera sensors in such a network need to be properly calibrated by determining their location, orientation, and range. This paper presents Snapshot, an automated calibration protocol that is explicitly designed and optimized for camera sensor networks. Snapshot uses the inherent imaging abilities of the cameras themselves for calibration and can determine the location and orientation of a camera sensor using only four reference points. Our techniques draw upon principles from computer vision, optics, and geometry and are designed to work with low-fidelity, low-power camera sensors that are typical in sensor networks. An experimental evaluation of our prototype implementation shows that Snapshot yields an error of 1-2.5 degrees when determining the camera orientation and 5-10cm when determining the camera location. We show that this is a tolerable error in practice since a Snapshot-calibrated sensor network can track moving objects to within 11cm of their actual locations. Finally, our measurements indicate that Snapshot can calibrate a camera sensor within 20 seconds, enabling it to calibrate a sensor network containing tens of cameras within minutes.","PeriodicalId":147887,"journal":{"name":"2006 3rd International Conference on Broadband Communications, Networks and Systems","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133874071","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}

LOCO MAC novelty lies in its backoff scheme that achieves short time collision resolution among many competing stations, even when they are hidden from each other. In LOCO-MAC the channel access time is calculated as a function of the station load, thus enabling to estimate the load of stations at the receiver side, regardless of the successful reception of transmission request. This load estimation is used to grant channel access to one of the stations whose load is the highest. Station's load is measured and normalized adaptively in terms of queue length and maximum end-to-end packet delay time. An analytical analysis to the throughput reveals that the expected throughput of LOCO MAC is ~80%. A network simulator was used to verify the effectiveness of the protocol under more realistic communication scenarios. Simulations results show that the high throughput is achieved almost regardless of the traffic load and is maintained at bursty traffic load distributions and even at loads that momentarily exceed the channel capacity. In addition, the fact that LOCO- MAC serves the most loaded station promotes fairness among stations, while maintaining high goodput, short queue lengths as well as short packet delays.","PeriodicalId":147887,"journal":{"name":"2006 3rd International Conference on Broadband Communications, Networks and Systems","volume":"39 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133133298","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}

In order to make OBS a viable solution, the wavelength scheduling algorithms need to be able to utilize the available wavelengths efficiently, while being able to operate fast enough to keep up with the burst incoming rate. For example, for a system with 32 wavelengths per link, each operating at 10 Gb/s, we need to process one BHC every 25 ns, in order to support an average burst length of 1 KByte. When implemented in hardware, the running time of the well-known horizon scheduler is O(1) for practical numbers of wavelengths. Unfortunately, horizon scheduling cannot utilize the voids created by previously scheduled bursts, resulting in low bandwidth utilization. To date, Min-SV is the fastest scheduling algorithm that can schedule wavelengths efficiently. However, its complexity is O(log m) and it requires lOlog m memory accesses to schedule a single burst. This means that it can take up to several microseconds for each burst request, which is still too slow to make it a practical solution for OBS deployment. In this paper, we propose an optimal wavelength scheduler using constant time burst resequencing (CTBR), which runs in O(1) time. The proposed CTBR scheduler is able to produce optimal wavelength schedules while having the same processing speed as the horizon scheduler. The algorithm is well-suited to high performance hardware implementation.","PeriodicalId":147887,"journal":{"name":"2006 3rd International Conference on Broadband Communications, Networks and Systems","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123894256","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 e-science applications often have large raw capacity requirements (tens of gigabits/second) and require global reach. The discipline scientists expect this type of performance to be deterministic and repeatable, and available in conjunction with other resources such as sensors, instruments, computational clusters, storage arrays, and the like. The DRAGON project, an NSF funded testbed in the Washington DC metropolitan area, has been developing open source generalized multi-protocol label swapping (GMPLS) based service concepts that provide dedicated and deterministic network resources to the e-science application. Using the GMPLS control plane and DRAGON extensions, an entire \"application specific topology\" can be established in an automated fashion across administrative boundaries, across heterogeneous network technologies, and can be instantiated in seconds rather than weeks or months. This paper describes the technologies being developed by the DRAGON project and some of the ways application specific topologies are being applied to advanced networked applications.","PeriodicalId":147887,"journal":{"name":"2006 3rd International Conference on Broadband Communications, Networks and Systems","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125324656","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}

Instead of upgrading the system performance independently in the metro and access networks, we propose a highly integrated metro-access network - the metro-access ring integrated network (MARIN). With MARIN architecture, the optical access network is integrated into MAN, such that the capacity upgrade in both networks can be achieved simultaneously without interfering the operation of existing MAN system. By interconnecting multiple access ring networks, all-optical path can be formed to route the MAN traffic between any metro hubs connected to MARIN. Fast tunable lasers are used in the central office of each access ring network to form a hybrid TDM/WDM access network architecture, and facilitate resource sharing, desirable network scalability, and routing efficiency of the metro traffic, which is the focus of this paper. wavelength routed optical burst switching (WR-OBS) is employed for route management of metro traffic. In MARIN, each access ring network emulates a distributed optical burst switch, controlled by the local central office. With WR-OBS for bandwidth and route allocation, the simulation results show that using multiple tunable lasers for simultaneous burst transmission and high-speed reconfigurable device at the joint node, the network performance of MARIN can be significantly improved.","PeriodicalId":147887,"journal":{"name":"2006 3rd International Conference on Broadband Communications, Networks and Systems","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127269112","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}
