Reliable transport protocols use the retransmission timeout management mechanism (RTO-MM) when a bad state of the wireless channel occurs, which temporarily blocks the transmission of data. In this paper, we suggest a new policy of timeout applied to the Stream Control Transmission Protocol (SCTP) called persistent timeout policy. This policy is based on the use of the channel status provided by the 802.11 link layer, through the cross-layer mechanism. The principle of this timeout is that when a bad state of the wireless channel blocks the sending of data, SCTP continuously observes the evolution of this state to detect the next favorable change before sending its segments. We evaluate the following two timeout policies (persistent and traditional RTO-MM) of SCTP in an ad hoc network, and also in comparison with the Transmission Control Protocol (TCP). Section I of this paper presents an overview of the SCTP protocol. Section II presents the principle of the persistent timeout policy. Section III presents the simulation results that are used to compare the two timeout policies of the two reliable transport protocols SCTP and TCP.","PeriodicalId":102045,"journal":{"name":"2012 Next Generation Networks and Services (NGNS)","volume":"153 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133982963","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}

Nevertheless, these protocols have not been designed for mobile members and roaming sources, and has not been tested in wireless and mobile environment since they were developed for multicast parties whose members and sources are topologically stationary. Studying and solving multicast issues in the stationary multicast infrastructure has been largely studied in the literature. However, fewer efforts have been spent in the specific problems of mobile members and sources. The main problematic of the multicast IP protocols in a Mobile IP environment is the frequent change of membership and members location, especially, the scenario of handover where a mobile source moves from attachment point in one sub-network to another one in another sub-network is challenging. A multicast source is identified by its Home Address HA. Since IP mobility implies acquisition of a new topologically Care-of-Address CoA at each handoff resulting in a change of identity of the multicast source, however, the established multicast routing states are always based on the home address of the mobile source. The key idea of this work is to make the handover of multicast sources transparent and avoid the reconstruction of the entire multicast-based tree, by using an architecture based in PIM-SM multicast distribution trees to hide the mobility of a mobile multicast source from the main multicast delivery tree. Simulation results show that good performance is achieved in terms of handoff latency, end-to-end delay, tree construction delay and others metrics.","PeriodicalId":102045,"journal":{"name":"2012 Next Generation Networks and Services (NGNS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130012073","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 area has been widely studied and solutions typically use data not freely available. A labeled available network traffic flow dataset, Kyoto2006+, has been recently created. Most existing works using Kyoto2006+ for network anomaly detection, apply various clustering approaches. Clustering approaches typically require thresholds for minimum size or distance, or the number of clusters. Results could be sensitive to the selection of such thresholds. This paper leverages existing spectral analysis and statistical analysis techniques for network anomaly detection. One well known spectral analysis technique is Haar Wavelet filtering analysis. It measures the amount and magnitude of abrupt changes in data. Another popular approach is a statistical analysis technique called Principal Component Analysis (PCA). PCA describes data in a new dimension to unlock otherwise hidden characteristics. Both approaches have strengths and limitations. In response, this paper proposes a Hybrid PCA-Haar Wavelet Analysis; a modified PCA which incorporates time shifting to account for changes over time is considered. In addition, the hybrid approach uses PCA to describe the data and Haar Wavelet filtering for analysis. Based on prototyping and measurement, an investigation of the Hybrid PCA-Haar Wavelet Analysis technique is performed using the Kyoto2006+ dataset. We present experimental results to demonstrate the accuracy and precision of the hybrid approach as compared to the two algorithms individually. Furthermore, tests to examine the impact of various parameters used in the algorithm are discussed.","PeriodicalId":102045,"journal":{"name":"2012 Next Generation Networks and Services (NGNS)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116515793","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}
