It is a time-varying Dynamic spectrum management (DSM) is one of the key problems in the design of cognitive radio(CR) networks. It is a time-varying and location-dependent optimization problem, equivalent to the well-known graph-colouring problem in graph theory. This problem is known to be NP-hard and computationally challenging to solve. Accordingly, finding the exact solution for the DSM optimization problem is typically not practical. In this paper, we introduce a novel self-organizing DSM scheme, which solves the DSM problem in a decentralized manner. The use of self-organization to address the DSM problem offers several benefits: decentralization and scalability ofthe network behaviour, computational simplicity, cost-effectiveness and bandwidth conservation. In the paper, we address the underlying principles involved in the design and implementation of the self-organizing DSM as well as a software testbed for demonstrating this novel approach.

Despite the contention issue, Optical Burst Switchingis planned to be deployed in the near future because it offers the required reactivity.Recourse to electrical processing to solve burst contentions has been disregarded because it can dramatically impact the end-to-end delay and the electrical memory requirements. Recently, the CAROBS transmission scheme has been proposed as an adapted response to the drawbacks of translucent architectures: By exploiting both edge and core traffic grooming, CAROBS significantly reduces the contention rate and the duration of the aggregation process. With the additional use of wavelength conversion, loss-less transfer is achieved with similar end-to-end delay and memory requirements as in all-optical OBS networks.The objective in this paper is to attain similar delay and memory performances for loss-less transfers without the support of wavelength converters. We propose a new train assembly process, called CTA, which reduces the time spent in electrical buffers by decreasing the offset times of the trains. The resulting reduction of the buffer occupancy allows the achievement of similar performances as with wavelength conversion, even in congested states, without investing in any specific equipment.","PeriodicalId":208564,"journal":{"name":"2010 8th Annual Communication Networks and Services Research Conference","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132993290","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}
