Traditional routing protocols may not suffice for real time communications which require QoS support from the network. Though there has been considerable research in this area, most of the routing protocols take into account a single QoS constraint. In this paper, we propose an adaptive distributed routing protocol for MANETs which provides a QoS aware path from a given source to destination. The novelty of the protocol lies in taking multiple QoS constraints into consideration. Admission control and bandwidth reservation schemes are incorporated in the protocol to satisfy the QoS constraints of the applications. Relevant information is stored at the intermediate nodes to achieve the required QoS. The protocol has been simulated on top of IEEE 802.11 MAC, in ns-2 network simulator, to show it's correctness and efficiency.","PeriodicalId":161120,"journal":{"name":"9th International Conference on Information Technology (ICIT'06)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127457083","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 discuss an exact expression for the expected value of route failure time when lifetimes of individual paths are independent and identically distributed random variables. When the lifetimes are not independent, we discuss an upper bound on route failure time. In order to validate the model, we simulate exponentially distributed random variables. The values of route failure time obtained from simulations are close to those obtained analytically.","PeriodicalId":161120,"journal":{"name":"9th International Conference on Information Technology (ICIT'06)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126031860","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 all the applications, outliers need to be detected to enhance the accuracy of the classifiers. Several different techniques, such as statistical, distance-based and deviation-based outlier detection exist to detect outliers. Many of these techniques use filter method. A wrapper method using the concept of instance typicality may also be used to detect outliers. This paper deals with a new wrapper method that builds an initial model using neural networks and treats values at the output of neurons in the output layer as the typicality scores. Instances with lowest output values are treated as potential outliers. In addition, the method is also useful to build compact and accurate classifiers by selecting a few most typical instances resulting in significant reduction in storage space. The method is generic and thus can also be used for instance selection with any kind of classifiers. Resultant compact models are useful for imputation of missing values.","PeriodicalId":161120,"journal":{"name":"9th International Conference on Information Technology (ICIT'06)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114480841","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 proposal is to realize the system, which checks the security aspects for authorizing the access and reveling the data to the user belonging to partner organization.

Secondly, it introduces the reversible logic implementation of the proposed carry look-ahead BCD subtracter.

Raga is a representation of the possible swaras that can occur in a given Carnatic song. This paper first deals with the segmentation of Carnatic vocal music and then attempts to find the pitch associated with each segment. We propose a two level segmentation algorithm to yield the probable swara segments. For each segment, pitch information is extracted to find the frequency of that particular segment. The fundamental frequency associated with the music signal conveys the overall pitch of the singer, which in turn corresponds to the middle octave swara 'Sa'. The frequencies associated with the segments are identified and the exact tagging of swara is performed to find the 7-swara combinations in the given music signal.","PeriodicalId":161120,"journal":{"name":"9th International Conference on Information Technology (ICIT'06)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124054367","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}
