In this paper, we propose a new architecture of an OSF based on tunable fiber Bragg gratings (FBGs). The main feature of the architecture is its ability to be used for both packet and circuit switching networks. Furthermore, the use of FBG endows the proposed design with simplicity, low insertion loss and low cost. In addition, the new architecture fits the operations of equally and unequally spaced channels and provides wavelength modularity. Finally, contention resolution is suggested using a multi-wavelength converter.","PeriodicalId":340950,"journal":{"name":"2009 First International Conference on Emerging Network Intelligence","volume":"1015 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123118029","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}

This paper presents a study about different pheromone evaluation models and how they react to possible changes in traffic rate. Observing how the pheromone value on a link changes, it could be possible to identify certain patterns which can indicate the path status. For this study, the behavior of the Ant System evaluation model was compared with a Temporal Active Pheromone model (a biological approach) and a Progressive Pheromone Reduction model with and without a maximum pheromone limit.","PeriodicalId":340950,"journal":{"name":"2009 First International Conference on Emerging Network Intelligence","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122708074","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 propose, simulate and analyze one relay network, and show that network coding along with redundancy can be used as a very efficient error recovery mechanism that greatly improves network reliability at very low computational and hardware cost. Thus, network coding can be an interesting method for reliability improvement in medical systems such as Wireless Body Area Networks (WBAN). A network coding scheme is proposed and simulated, and the optimal method according to that scheme is analyzed. Practical and fast decoding algorithm is presented. We then simulate the proposed network and the optimal method and compare it with the regular redundant network. Simulations show great improvement compared to regular redundant transfer, for very small computational cost. Finally, we simulate and show that the proposed network is still functional and operational even in case where one relay point is off.","PeriodicalId":340950,"journal":{"name":"2009 First International Conference on Emerging Network Intelligence","volume":"205 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131236679","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 this paper, a resource discovery service that tackles the issues identified in a decentralized and distributed DHT-based caching architecture for media content distribution is presented. In the proposed approach, complex queries on dynamic peer resources can be performed. This discovery service is layered over an underlying DHT overlay network which connects all the peers, based on the combination of a spanningtree built bottom-up by mapping DHT peers to their parents, and routing indices which allow peers to efficiently lookup other peers, matching some resource constraints. Measures from simulation as well as from a real implementation are analyzed.","PeriodicalId":340950,"journal":{"name":"2009 First International Conference on Emerging Network Intelligence","volume":"1989 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125493312","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}

To ensure application security, the routing protocols are assumed to be trusted. Correct forwarding of packets requires the prior exchange of information among routers, using the appropriate routing protocol. Valid construction of the routes requires that the exchanged information be received from a legitimate neighbor, and that it not be altered en route, i.e., the inter-router communication has to be secure. This requires, in turn, an architecture for managing the necessary security associations and keying material within an administrative region. After reviewing current work and existing security tools, a proposal is made for a novel architecture to manage the router updates. The operations within this architecture are detailed, and its advantages are explained.","PeriodicalId":340950,"journal":{"name":"2009 First International Conference on Emerging Network Intelligence","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114777489","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}

Therefore, EPON has been considered as an attractive solution for the next generation broadband access network. In this paper, we present an enhanced Dynamic Bandwidth Allocation (eDBA) algorithm for EPON network. Our mechanism allocates effectively and fairly the transmission bandwidth to ONUs. Some other algorithms, such as the Dynamic Bandwidth Allocation (DBA), introduce an idle period during the time that the Optical Line Terminal (OLT) is executing the bandwidth assignment procedure. During this idle time, no data are sent by any ONU node to OLT. In order to exploit this wasted bandwidth, the proposed algorithm calculates a vector of complementary bandwidth amounts to assign to the ONUs during the idle time. Finally, we simulate a multiservice-based EPON network configured with the eDBA mechanism. Obtained results are compared to the ones obtained with two other algorithms: Dynamic Bandwidth Allocation (DBA) and the Interleaved Polling with Adaptive Cycle Time (IPACT). We show that eDBA can significantly improve the network performance in term of packet access delay and packet loss rate as compared with other algorithms.","PeriodicalId":340950,"journal":{"name":"2009 First International Conference on Emerging Network Intelligence","volume":"157 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131817361","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}
