Typical published results using this tool show node counts on the order of hundreds of nodes. However, realistic sensor and vehicular networks may contain many more nodes than that. One reason for this discrepancy is the computational cost of evaluation via simulation. Currently, cluster computers are becoming preferred over expensive multi-processor supercomputers for improving computational output. We present the design and implementation of a parallelization of JiST, the discrete event simulator core of JiST/SWANS. JiST uses unique dynamic byte-code rewriting to simplify the development of applications and has been shown to perform well running small- or medium-scale wireless network simulations on single processor systems. We propose an optimistic cluster-based architecture and apply it to JiST. Simulation entity memory is distributed evenly across all nodes in the cluster, resulting in linear memory growth. Details of the simulation engine including the complex event execution synchronization are hidden entirely from the application, easing development and debug time. Since JiST is the simulation backend of the SWANS wireless network simulator, this result is the first step in simulating large networks using SWANS in reasonable periods of time. Results presented show the performance of our parallelization of JiST is in line with the performance of other existing parallel discrete event simulators.","PeriodicalId":197677,"journal":{"name":"7th International Symposium on High-capacity Optical Networks and Enabling Technologies","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131836421","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 the IEEE 802.11 MAC protocol when two nodes are communicating with each other, all other nodes in the transmission zone are required to remain idle. With the use of directional antennas, it is possible to have two pairs of nodes located in each other's transmission range to communicate simultaneously; this increases the spatial reuse of the wireless channel. However, directional antennas suffer from deafness and hidden terminal problems and therefore new mechanisms are required for exploitation of the directional antennas in an intelligent manner. In this paper we present a scheme based on switched beam directional antenna with busy tone for controlling the directional antenna beams for maximum spatial reuse and saving in energy consumption. The purpose of the busy tone signal is to inform nodes in the transmission zone about the current transmission which helps solving hidden terminal and deafness problems. We present performance evaluation results which confirm the significant improvement in both throughput and energy consumption. We also study the effect of the number of beams on the throughput and energy consumption.","PeriodicalId":197677,"journal":{"name":"7th International Symposium on High-capacity Optical Networks and Enabling Technologies","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131155627","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}

Multicast nodes must be equipped with light splitters. Light splitters are expensive equipment. Therefore, a limited number of optical nodes will have this splitting capability. A good placement of optical splitters can increase the efficiency of the multicast signaling and routing techniques on the one hand, and reduce the number of splitters on the other hand. This leads to faster multicast trees setting up, lower data transmission delays, and less traffic on the network links; thus saving of optical links capacity for other multicast and unicast transmissions. In order to achieve efficient multicasting in optical network, we propose to take into account network characteristics i.e. link capacity and node degree when placing the optical splitters. The benefits of the smart placement of light splitters will be clearly shown in heterogeneous optical networks, where multicast traffic is not uniformly distributed over the network, and optical links connecting different nodes in the network have different characteristics.","PeriodicalId":197677,"journal":{"name":"7th International Symposium on High-capacity Optical Networks and Enabling Technologies","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121726772","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}
