In order to overcome this disadvantage, a new search strategy named TTL-Search based on the local caching and the scope of searching requests is proposed in this paper. According to this strategy, the searching process is divided into two stages, and each stage adopts different forwarding strategies. Analysis and experimental results show that, TTL-Search can overcome blindness of flooding search, and also can reduce redundancy overhead caused by query to some extend. So it can improve query success rate, and can be efficiently applied in the unstructured P2P network searching.","PeriodicalId":255246,"journal":{"name":"2010 Second International Conference on Communication Software and Networks","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134007272","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 proposed a method to adjustment index correlation based on Orthogonalization. The advantages of this method for evaluation damage degree of network have been demonstrated from two simulation experiments. One is damage degree comparisons in difference basic topologies. Another is worm propagation in campus topology. The results show that network suffered by distinct damage with the same packet creation rate and traffic generate model in different basic topologies. The worm propagation experiment has demonstrated that the method can reflected the dynamic process of network availability damage accurately and integrally.","PeriodicalId":255246,"journal":{"name":"2010 Second International Conference on Communication Software and Networks","volume":"57 42","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134225561","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}

SCFDMA uses DFT spreading prior to OFDMA modulation to map the signal from each user to a subset of the available subcarriers i.e., single carrier modulation. The efficiency of a power amplifier is determined by the peak to average power ratio (PAPR) of the modulated signal. In this paper, we analyze the PAPR in 3GPP LTE systems using root raised cosine based filter. Simulation results show that the SCFDMA subcarrier mapping has a significantly lower PAPR compared to OFDMA. Also comparing the three forms of SCFDMA subcarrier mapping, results show that interleave FDMA (IFDMA) subcarrier mapping with proposed root raised cosine filter reduced PAPR significantly than localized FDMA (LFDMA) and distributed (DFDMA) mapping. This improves its radio frequency (RF) power amplifier efficiency and also the mean power output from a battery driven mobile terminal.","PeriodicalId":255246,"journal":{"name":"2010 Second International Conference on Communication Software and Networks","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115120683","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 scalability, and function coverage of these six software packages are assessed and compared. Some randomly generated datasets are used to evaluate the performance of these software packages with regard to input/output (I/O), basic graph algorithms, statistical metrics computation, graph generation, community detection, and visualization. A metric regarding both numbers of the nodes and the edges of complex networks, which is called Maximum Expected Network Processing Ability (MENPA), is proposed to measure the scalability of software packages. Empirical results show that these six software packages are complementary rather than competitive and the difference on the scalability among these six software packages may be attributed to the varieties in both of the programming languages and the network representations.","PeriodicalId":255246,"journal":{"name":"2010 Second International Conference on Communication Software and Networks","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129809724","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}

Though all query nodes in a large group are running the same application, they might join various multicast groups depending on their interests. However, despite the significant importance of message delivery order guarantees, little work on gossip-based protocols exists supporting multicast groups and satisfying these constraints in a scalable way. In this paper, we present an efficient and scalable causal order guaranteeing multicast protocol to use only local views supporting multi-groups. In the proposed protocol, multicast groups are defined by interests associated with the processes and join/leave messages are disseminated by gossip communication based on local views. So, group memberships are dynamically changing by their own members in multicast groups with high probabilistic reliability. Also, group ID order lists are delivered to possibly overlapping multicast groups to ensure causal order delivery. Therefore, these features of the protocol might result in its very low view management cost compared with the cost incurred by maintaining hierarchical member list for delegate groups in the previous protocols.","PeriodicalId":255246,"journal":{"name":"2010 Second International Conference on Communication Software and Networks","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128881091","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}
